Cellular Respiration

The third step in aerobic cellular respiration is the electron transport chain. NADH and FADH2 initiate the electron transport chain and transport electrons down a chain of reactions. NADH or FADH2 will work with electrons and oxygen to convert ADP to ATP. During this process, NADH loses its hydrogen and creates a hydrogen concentration gradient across the inner mitochondrial membrane. This hydrogen concentration gradient produces more ATP and NADH is now NAD+. At the end of this process, water and ATP is

To be able to carry on metabolic processes in the cell, cells need energy. The cells can obtain their energy in different ways but the most efficient way of harvesting stored food in the cell is through cellular respiration. Cellular respiration is a catabolic pathway, which breaks down large molecules to smaller molecules, produces an energy rich molecule known as ATP (Adenosine Triphosphate) and a waste product that is released as CO2.

Cellular respiration and effects of pollutants and carbohydrates on its rate is determined . its purpose is to determine the importance of cellular respiration on the process of life. Respiration is process that take place in cell to convert the biochemical energy to ATP.

First glucose is broken down in the process called glycolysis, then the pyruvate molecules are moved to the mitochondria, when this is happening the pyruvate molecules are converted into 2-carbon molecules these molecules then enter the Kreb Cycle. Moving on the energy created will now enter the electron transport chain, this energy will then produce ATP. The reactants are glucose and oxygen and the products are ATP, water, and carbon dioxide. During the Cellular Respiration glucose is being oxidized, along with carbon. On the other hand Oxygen, NAD+ and FADH are being reduced in Cellular Respiration.

When it comes to Biology, there are so many things that you can learn about. My favorite is learning more and more about how the body works and all the interesting facts that come along with it. I am going to be writing about Cellular Respiration.

Some knowledge that is needed before performing this lab are as follows: First of all, cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules. This process includes glycolysis, the Krebs cycle, and the Electron Transport Chain. Glycolysis is a process that takes place in te cytosol and it oxidizes glucose into two pyruvate. Glycolysis also makes ATP and NADH. The Krebs Cycle occurs in the mitochondria and this process takes the pyruvate and breaks it down into carbon dioxide. But it also produces 3 CO2, 1 ATP, 1 FADH2, and 4 NADH. The electron transport chain takes place in the inner mitochondrial

Cellular respiration is a group of reactions that occur when a cell turns the energy from food and nutrient sources into ATP, releasing the rest of the

Cells are the basic units of life and their processes are vital to the functioning of all organism. The reactions of photosynthesis and cellular respiration are complimentary and are also the most important pathways on the Earth. Photosynthesis is a process that converts carbon dioxide into organic compounds in presence of sunlight. Cellular respiration is the set of metabolic reactions that take in cells of living organisms that convert nutrients like sugar into energy , which is known as ATP (adenosine triphosphate), and waste products. The two processes are closely related and likewise, they share many similarities and differences

ATP stands for adenosine triphosphate. It is a coenzyme that cells use to store energy. Also ATP is present in all cell's cytoplasm and nucleus as well because it’s vital for proper life functions in plants and animals.

Cellular respiration is a sequence of three metabolic stages. Stage one is glycolysis and occurs in the cytoplasm. Stages two and three occur in the mitochondria and are respectively called the Krebs cycle and the electron transport chain. Both autotrophs and heterotrophs use these metabolic stages to produce the energy required to grow, reproduce and undertake maintenance, in the form of ATP (Flinders University , 2018). A step in the Krebs cycle can see an enzyme catalysed conversion of succinate to fumarate where an electron is transferred from one complex to another, a redox reaction (Knox, et al., n.d.). Substrate concentration is a variable used to increase the rate of a reaction. It is a limiting factor however, up until a certain point,

This is known as the light dependent reaction of photosynthesis. The goal of photophosphorylation is to take the energy from sunlight and convert it into chemical energy for the Calvin cycle. The Calvin cycle then takes this chemical energy and uses it to make glucose. Photophosphorylation begins when a photon (packet of light) is absorbed by a pigment (light absorbing molecule), which is attached to a protein along the thylakoid membrane of the chloroplast. The energy from the photon creates resonance (electron passing from one pigment to the next), which eventually reaches a special reaction center. The reactions center is a protein that houses a special pair of chlorophyll molecules capable of releasing electrons. When the chlorophyll molecules get excited, they release two electrons. These two electrons then move along the membrane through a series of specialized protein releasing energy as they go. This action creates an H+ gradient inside the lumen of the chloroplast. Eventually the electrons reach the end of the chain and attach onto electron carriers. The H+ flow across the ATP Synthase protein where they meet up with ADP (andesine diphosphate) and Pi (phosphate group) to from ATP. The chemical energy created can then be used in the Calvin

To understand this experiment, it is important to have a basic comprehension of what cellular respiration is, how it functions, and the different variables that can affect it. All organisms need some form of energy, taken from outside sources, to function and to facilitate growth and development. Mitochondria within cells are able to harvest the chemical energy stored in food molecules, such as glucose, amino acids, and fatty acids,  and break it down through chemical oxidation in cellular respiration. Cellular respiration is an ATP, adenosine triphosphate,  synthesizing process that also produces carbon dioxide and water as waste (Cellular, 2016). The reactions that take place in respiration are catabolic which means they break down complex molecules into simpler molecules while releasing energy. The energy released in this process is central to the production of ATP. ATP is a macromolecule consisting of a ribose, a nitrogenous base, and a chain of three phosphates. ATP is used to transport energy throughout the cell and releases the stored energy by breaking the bond on the outermost phosphate group (Bergman, 2015).

Pulmonary (external) respiration or ventilation involves the intake of oxygen, and the elimination of carbon dioxide from the body. While oxygen is an essential element to the in the production of energy, and the first thing that comes to mind when the topic is about breathing, it is the carbon dioxide that plays the most important role when it comes to the regulation of ventilation (Pearson 12). Contrary to what most people believe, carbon dioxide is more than just a waste product of the body’s metabolic process called aerobic (internal) cellular respiration. Blood levels of CO2 play a vital role in controlling rates of breathing that that has a corresponding effect on the blood’s pH levels. Blood’s pH imbalance or irregularities and troublesome

Cellular respiration is when cells break down simple food molecules like glucose and release the energy they contain. This is a 2 stage. The first stage starts in the in cytoplasm when glucose molecules are broken down. The second stage starts in the mitochondria which is when small molecules of glucose molecules are broken down. The chemical reactions require oxygen and lots of energy released. Heterotrophic is when animals can't make their own food. We are heterotrophic because we can not make food by our self. Respiration is when we take in oxygen. When we breath we let out carbon dioxide. Chemical energy is when the chemical goes through a chemical reaction which turns into a chemical substances.
