In order for the body to function properly, it requires energy which mainly comes from carbohydrates and fats we would take in as food. Carbohydrates are broken down into glucose which is soluble in blood. It is transported by the blood cells all around the body where it reacts with oxygen and will produce carbon dioxide (CO2), water (H2O) and energy.
C6H12O6 +6O2 ------------6CO2 +6H2O +Energy
Glucose + Oxygen Carbon Dioxide + Water + Energy
Carbon dioxide and water are formed during respiration(the burning of food in the cells) and are transferred through the different organs of the body. The energy released in respiration fulfils the energy needs of the body.
The process that takes place in presence of oxygen is called aerobic respiration. During this, molecules are broken down in order to get hold of bio-chemical energy and has oxygen. Molecules used by cells in aerobic respiration are glucose, amino acids and fatty acids.
Glucose + Oxygen → Energy + Carbon Dioxide + Water
Arobic respiration is an energy making process. Up to 38 molecules of ATP are produced for every utilised molecule of glucose during the process of aerobic respiration. The process of aerobic respiration breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules.
The term anaerobic means without air, meaning it takes place without oxygen. Anaerobic respiration is the process of oxidation of molecules in the absence of oxygen. This produces energy
In cellular respiration, glucose and oxygen are taken into the cells, then they are converted to carbon dioxide, water and ATP energy and some other energy. Some of the ATP energy is used in photosynthesis; a large amount of
There are two types of cellular respiration, aerobic and anaerobic. Aerobic respiration occurs when there is oxygen present and in the mitochondria (in eukaryotic cells) and the cytoplasm (in prokaryotic cells). Aerobic respiration requires oxygen; it proceeds through the Krebs cycle. The Krebs cycle is a cycle of producing carbon dioxide and water as waste products, and converting ADP to thirty-four ATPs. Anaerobic respiration is known as a process called fermentation. It occurs in the cytoplasm and molecules do not enter the mitochondria for further breakdown. This process helps to produce alcohol in yeast and plants, and lactate in animals. Only two ATPs are produced through this process. In yeast fermentation is used to make beer, wine, and whiskey.
Cellular respiration is the chemical process in which organic molecules, such as sugars, are broken down in the cell to produce utilizable energy in the form of ATP. ATP is the chemical used by all of the energy-consuming metabolic activities of the cell. In order to extract energy from these organic molecules, cellular respiration involves a network of metabolic pathways dedicated to this task.
The most important waste product produced during cellular respiration in cells is carbon dioxide. Each molecule of glucose produces six molecules of carbon dioxide during aerobic respiration. Carbon dioxide diffuses across the cell membrane into the bloodstream, where it's carried back to the lungs to be released during exhalation. Unlike carbon dioxide, water isn't a waste that requires any specialist disposal since cells and the bloodstream are made up of predominantly water.
Cellular respiration is a redox reaction that combines glucose & oxygen to produce carbon dioxide, water, and energy.
There is a small amount of carbon dioxide and more oxygen in the body because of gases exchange this is where oxygen form the lungs is transferred in to the blood and carried to the heart and when carbon dioxide is carried in to the lungs forms the blood and is exacted outwards by breathing. Mitochondria also need oxygen to create carbon dioxide for the body so the gas exchange can happen again. Outside the body there is a smaller amount of oxygen but it is still higher than CO2.
Your body requires energy in order to be able to perform tasks. Energy comes in many different forms. They are chemical, light, sound, heat and mechanical. You can get energy from different food substances i.e. glucose, fatty acids, sugars and amino acids. To be able to get the energy from these food substances energy needs to be released with oxygen. This is known as aerobic respiration. The role that energy plays in our body is the process of moving molecules in and out of our cells while breaking down the larger molecules and building new molecules. The cardiovascular system transports oxygenated blood around the body and to the cells. It will then collect the deoxygenated blood which is ready for the excretion from the cells. The cardiovascular system will deliver the nutrients oxygen and glucose via the blood stream. Oxygen is need for aerobic respiration to occur. The cardiovascular system will pump oxygen and nutrients carrying blood throughout the body. The glucose molecules that are carried by the blood are transported into the cells. Along with the oxygen that is diffused into the cells they are used in respiration to produce ATP. The respiratory system is responsible for bringing in oxygen as well as using it to burn the nutrients that we need for energy. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream
Aerobic respiration happens only when oxygen is presented in the cell. Aerobic respiration starts with pyruvate crossing into the mitochondria. When it passes through, a Coenzyme A will attach to it producing Acetyl CoA, CO2, and NADH. Acetyl CoA will enter into the Krebs cycle. In the Krebs cycle Acetyl CoA will bound with Oxaloacetic Acid (OAA), a four carbon molecule, producing the six carbon molecule, Citric Acid. Citric Acid will reorganize into Isocitrate. This will lose a CO2 and make a NADH turning itself into alpha ketoglutarate, a five carbon molecule. Alpha ketoglutarate will turn into an unstable four carbon molecule, which attaches to CoA making succinyl CoA. During that process a CO2 and NADH is made. An ATP is made when CoA leaves and creates Succinate. This molecule is turned into Fumarate, creating two FADH2 in the process. Then Fumarate is turned into Malate then into OAA making two NADH. Only two ATP is produced in Krebs cycle but the resulting NADHs and FADH2s are passed through an electron transport chain and ATP synthase. When the molecules passes through that cycle a total of 28 ATP molecules are produced. In all aerobic respiration produces 32 ATP and waste products of H2O and
Our body produces energy called ATP. ATP is the renewable energy source for our cells that consists of 3 phosphates, a sugar and an adenine ring. ATP can be produced in two ways, through aerobic respiration or anaerobic respiration. Aerobic respiration occurs when there is oxygen, and anaerobic occurs when oxygen is not available. Also there are normally 3 phases in respiration, glycolysis, krebs cycle, and the electron transport chain. During glycolysis the glucose splits into two
Like Photosynthesis, cellular respiration is also a redox reaction where glucose loses electrons and hydrogen atoms to produce carbon dioxide causing the glucose to become oxidized. At the same time, oxygen gains electrons and hydrogen atoms, reducing it to water.
Cellular respiration is a process that happens in all living eukaryotic cells. What cellular respiration does is turn food often carbohydrates into energy for our bodies. Cellular respiration starts with a carbohydrates sugar called glucose. What it does is alter and break down the six carbon molecule glucose and altering it creating two three carbon molecules called pyruvic acids in an anaerobic process called glycolosis (Cellular respiration). What this process does is create two ATP molecules which are basically molecules which provide energy to run all cellular processes in our bodies (king). However, from here in the process can turn aerobic, meaning using oxygen if present or anaerobic meaning when oxygen is not present in a
All living organisms need the energy to perform the basic life functions. Cells use a process called cellular respiration to obtain the energy needed. In cellular respiration, cells convert energy molecules like starch or glucose into a cellular energy called Adenosine triphosphate(ATP). There are two types of cellular respiration which include: Aerobic and Anaerobic respiration. In aerobic respiration, cells will break down glucose to release a maximum amount of ATP this takes place in the presence of oxygen. Aerobic also produces carbon dioxide and water as waste products and it takes place in the mitochondria. on the other hand, anaerobic respiration, a metabolic process, also produces energy and uses glucose, but it releases less energy and does not require the
Cellular respiration releases energy as organic molecules are oxidized. ATP or Adenosine triphosphate is where this energy is stored. Cells need ATP to metabolize and use it to transport, reproduce, and various other important activities. Through a process called glycolysis, glucose breaks down to pyruvate as glucose is oxidized. In ATP, energy released from glucose is stored. Cells can perform glycolysis with or without the presence of oxygen. With oxygen, cells go through the Krebs cycle, in which the cells can oxidize pyruvate to carbon dioxide. The organisms that use this aerobic respiration after glycolysis are called aerobes.
In order for cells to grow, divide, and stay active, they must have sufficient energy. This energy comes from the oxidation of organic molecules such as glucose in respiration. Respiration is a series of oxidation taking place in all living cells releasing energy from organic compounds such as glucose. All respiration involves oxidation reactions and therefore all cells must have a constant supply of oxygen. In order for this to happen the exchange of gases between respiring cells and the environment are required. Gas exchange is a process by which oxygen gets into cells and carbon dioxide is released. Respiration creates the constant demand for oxygen and a release of carbon dioxide.
Mitochondrial respiration (aerobic metabolism) occurs in the mitochondria of the cells when the oxygen supply is sufficient to meet the oxygen demands (Smith, 2002).
