Food molecules of chemical energy is released and partially captured in the form of ATP in the process in cellular respiration. Glucose is most commonly used as an example to examine the reaction of Cellular respiration but other fuels that can be use are fats, proteins and carbohydrates. The formula for cellular respiration is glucose + oxygen --> carbon dioxide + water + energy and the chemical equation for it is C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP. Cellular respiration can be split in to three metabolic processes: glycolysis, the Krebs cycle, and oxidative phosphorylation. Each of these occurs in a specific region of the cell.

Different concentrations of glucose or different temperatures of the glucose solution could also be used as the independent variable in order to establish the most efficient concentration or temperature. It could also be relevant to measure the thermal energy produced from yeast aerobic respiration by constantly bubbling oxygen gas through a glucose solution. Similar calculations could be carried out to compare the theoretical and practical energy produced. Conclusion The hypothesis was accepted: the temperature of the yeast solution containing glucose did rise in temperature due to the fermentation of glucose by the yeast.
The two processes take place in different parts of the cell; photosynthesis takes place in chloroplasts while cellular respiration occurs in the mitochondria (Prentice Hall). Cellular respiration allows organisms to convert food into usable energy through glycolysis, the Krebs Cycle, and the electron transport chain. The net ATP production from a single glucose molecule through cellular respiration is 36 ATP molecules, with two ATP molecules from glycolysis, two ATP molecules from the Krebs Cycle, and 32 ATP molecules from the electron transport chain. Because cellular respiration plays an important role in helping an organism function properly, an organism would die without this process (Dr. Fankhauser).
Fermentation is when bacteria or other microorganisms chemically breakdown a substance while giving off heat. Fermentation is used by making many food products, an drink products such as beer, and also fuel. Fermentation and Cellular Respiration are alike in many ways such as organisms make energy by breaking down glucose into energy. They are different because Fermentation makes ATP, while chemical respiration using nutrients to create energy and turns it into adenosine triphosphate. (Carter J.S.
Cellular respiration is the oxygen-requiring reactions, occurring in the mitochondrion, that breaks down the end products of glycolysis into carbon dioxide (CO2) and water (H2O), while capturing large amounts of energy as adenosine triphosphate (ATP). Most cells can metabolize a variety of organic molecules to produce ATP. Virtually, all cells metabolize glucose for energy, at least part of the time. Secondly, glucose metabolism is less complex than the metabolism of most other organic molecules. The formula for complete glucose metabolism is the opposite of photosynthesis.
The citric acid cycle receives the acetyl CoA, and begins its system. This system occurs inside the mitochondrion matrix in eukaryotes and in the cytoplasm in prokaryotes. The inputs that start the CAC are water, acetyl, and oxidized electron carriers. For every acetyl group the cycle goes over, there are usually two carbons in the form of carbon dioxide removed, and four pairs of hydrogen atoms are used to reduce carrier molecules. The two-carbon acetyl group combines with the four-carbon oxalacetate and in turn form a six-carbon citrate.
Photosynthesis “is an endergonic suite of reactions that reduce carbon dioxide to glucose or other sugars” (Freeman et al. 2014). Cellular respiration provides plants and many other organisms with energy. Many organic molecules react with oxygen converting it into carbon dioxide, water and energy usually in the form of adenosine triphosphate. The process of oxidizing glucose occurs in two different stages in respiration.
(HallyHosting, n.d) The next stage of glycolysis occurs in thecytoplasm of the mitochondria. This is called the link reaction, also known as oxidative carboxylation. Oxygen is required in this stage so is an aerobic respiration and completes the conversion of pyruvate. The 2 pyruvic acid molecules, or also known as pyruvate, enter into the mitochondria, where the hydrogen and carbon dioxide become removed from them creating t... ... middle of paper ... ...oup to be added to ADP. This then forms ATP.
The acetyl CoA is then joined with oxaloacetic acid to produce a 6-carbon citric acid. The Krebs cycle can also be referred to as the citric acid cycle. Once the cycle starts moving through each successive step, atoms of the citric acid are rearranged to produce intermediate molecules called keto acids. Through this cycle each of the two pyruvic acids each create 1 ATP 3 NADH and 1 FADH2. After this process the real ATP maker in the three-step process of cellular respiration can occur, the electron transport

Photosynthesis requires that chlorophyll is present to process light and at the same time is dependent on light therefore would not occur without one or both. It is obvious that they are both reliant on the other, without photosynthesis to produce the oxygen chemotrophs breathe in order to metabolize glucose for energy. Works Cited 1.
