Lab Report On Cellular Respiration

This includes cells in our bodies as well as cells found in foods like yeast. ATP is a specific molecule that provides energy in a form that cells can use for cellular processes. Cellular respiration is a process that cells use to transfer energy from the organic molecules in food to be released into ATP energy and carbon dioxide. The release of energy from organic molecules and precisely glucose is an example of cellular respiration. Energy is essential for growth, repair, and movement in living organisms. Cellular respiration allows the cells to use the energy from each glucose molecule more efficiently in order to make as many ATP molecules as possible and produce high levels of carbon dioxide. Carbon dioxide is a colorless gas that is crucial to all living organisms on this planet. Carbon dioxide production can be directly related to the energy production from fermentation. It is these complex cellular processes that will be further examined in this research

Muscle cells rely on cellular respiration for energy. During normal physical activity the cells are supplied with oxygen to convert glucose to ATP, CO2 and water. During prolonged intense physical activity the muscles are not supplied with enough oxygen to produce ATP for energy. Therefor the muscles rely on cellular fermentation to break down glucose. This method yields less ATP and builds up lactic acid which makes muscles burn. In this lab students will use prolonged repetitions of squeezing a clothespin to analyze the effects of cellular fermentation on the muscles ability to do work.

All living organisms such as prokaryotic and eukaryotic cells require energy to carry out a large number of activities to help them survive daily. Cellular respiration is a process that provides cells with energy to full fill these requirements for survival. Cellular respiration is an exergonic reaction that extracts chemical energy stores in the covalent bonds of organic nutrients such as sugars,fats. and amino acids, and transfers it into bonds of ATP. ATP provides energy that drives nearly all biochemical reactions in cells and synthesis of macromolecules.

Respiration is when enzymes in cells cause protein synthesis and photosynthesis to happen. Respiration is a crucial part of life because all living organism would have to respire to live. When respiring animals and human let in oxygen from plants and then let out a waste product which is carbon dioxide.

Cellular respiration is the process of converting biochemical energy obtained from nutrients into energy in the form of adenosine triphosphate (ATP) to fuel cellular activity (). The equation for this process is as follows:

Cellular respiration is the process in which glucose is broken down into energy (ATP). There are 3 main steps to do this, glycolysis, the Krebs cycle (also called the citric acid cycle), and electron transport. Cellular respiration can also be summed up into this equation, C6H12O6 + 6O2 → 6CO2 + 6H2O + Chemical Energy (in ATP). The total amount of ATP produced by cellular respiration is 36.

The relationship between breathing and cellular respiration is that they are both forms of respiration since they both take in oxygen and expel carbon dioxide.

To begin, cellular respiration, also referred to as the aerobic harvesting of food molecules by cells, provides energy for life. Cellular respiration happens within the mitochondria of a cell. Within the mitochondria, O2 is consumed as glucose and then broken down into CO2 and H2O. Then, the cell captures energy released in ATP. Energy is lost as heat while the CO2 and H2O released by cellular respiration is then converted to glucose and O2 by photosynthesis. Cellular respiration can produce up to 38 ATP molecules for each glucose molecule.

Cellular Respiration is the combination of metabolic cells and processes that occur within the organisms cells. This process coverts biochemical energy into ATP and results in the removal of waste products. There are four main steps of Cellular Respiration. Glycolysis, Transport Reaction, Citric Acid Cycle and Oxidative Phosphorylation. These processes and or steps involved in cellular respiration are known as catabolic reactions. These reactions are important because they are what cause the larger molecules to break down into smaller molecules releasing energy that is necessary in order to carry out the rest of the process.

Cellular respiration comprises of a series of metabolic reactions that are vital to life. In cellular respiration, the energy from sugars (glucose) are released and are stored in a more readily available form, called adenine triphosphate (ATP). ATP is used as an energy source, in particular to drive reactions that occur inside the cell. Hence, without cellular respiration, organisms would find it difficult to perform simple tasks vital for survival.

Cellular respiration is the oxidation of organic compounds that occurs within cells, producing energy for cellular processes. Cellular respiration is very significant because without it humans and other animals couldn't generate energy for basic functions. “Sir Hans Adolf Krebs received the Nobel prize for medicine in 1953 for his discovery of the Krebs cycle in 1937”(Share). Long before Krebs discovered the Krebs cycle (which is one of three stages of cellular respiration), cellular respiration was taking place. Cellular respiration is an exothermic redox reaction which releases heat (energy). The energy produced

The first step of cellular respiration is glycolysis which occurs in the cytoplasm. During glycolysis, glucose is broken down into two molecules of pyruvic acid and four molecules of ATP. Next, the Krebs cycle occurs in the mitochondria. Enzymes control all reactions which occur in the Krebs cycle; during this step carbon compounds are rearranged and electrons are gathered in preparation for the electron transport chain. The electron transport chain occurs in the membrane of the mitochondria and is the last step of cellular respiration. It uses energy from the electrons being passed along a protein chain to create 32 ATP (and H2O which is a byproduct). This lab explores the effect of exercise on the rate of cellular respiration. To record the effects, bromothymol blue was utilized. Bromothymol blue is a solution which allows for detection of cellular respiration by changing color from blue to yellow when coming in contact with

Cellular respiration is a process that occurs in mitochondria, the powerhouse of the cell. It allows for cells to produce energy, more specifically ATP, in order for them to survive. Cellular respiration is defined as “a catabolic pathway for the production of adenosine triphosphate” (Bailey). It involves “both aerobic and anaerobic respiration” but usually is referred to as “aerobic respiration” (Notes). During this process, food molecules such as glucose react with oxygen to form carbon dioxide, water, and ATP. The chemical energy that is stored in food molecules are extracted and then used to generate ATP.

Cellular respiration are sets of metabolic reactions and processes that are taking place inside the cells that converts bio-chemical energies from food/nutrients into adenosine triphosphate ATP and after that release waste products. Energies are the forms of equally shared electron as reactant, and the products which form equally shared covalent bond, and during this process the potential energy was lost. So the respiration is the main way for a cell to gain useful energy to fuel its cellular activities. Most of the reactions occur in series of biological steps, a lot of these are redox reaction of themselves. We can define fermentation as a metabolic process that changes glucose into acids, gases and alcohol. There are two types of fermentation 's. These are alcohol fermentation and lactic acid fermentation. These fermentations occur in yeast and bacteria, as well as in the muscle cells, after excessive use of muscle cells, cells are starved for oxygen, this is where lactic acid buildup in the muscle cells. The process of fermentation normally happens without oxygen, and it does not go through the electron transport chain, this is the difference between fermentation and cellular respiration.

Cellular respiration is the catabolic pathways of aerobic and anaerobic respiration, which break down organic molecules and use an electron transport chain for the production of ATP (Reece et al Chapter 9). Basically what that means is that we all need energy to function so the energy we get, we get it from the food we consume. The way that we harvest the energy is through cellular respiration. There are two main types of cellular respiration, an anaerobic respiration and an aerobic respiration. For gas change to happen that one final electron act as an acceptor in cellular respiration, and it processes the oxygen that was taken in and that is how aerobic respiration takes place. As for anaerobic respiration, it is a catabolic pathway that accepts the electrons at the end of the electron transport chain (Reece et al Chapter 9). So because of there have to be an exchange between oxygen and carbon dioxide with the environment and the cells, the total cellular respiration rate which is the same as the metabolic rate, this can happen estimating the measure of gas exchange from the individual (Marshall et al 1). Gas exchange can be used to estimate metabolic rates, this can happen using a respirometer. A respirometer measure the oxygen that get taken in by the organism. The metabolic rate is the overall sum of the energy that an animal have. There are a few things that can affect the metabolic rate, one being the mass. The
