Chapter 9 Study Guide 1. Explain the difference between aerobic respiration and fermentation. Fermentation is partial degradation of sugars that occurs without oxygen. Aerobic respiration consumes organic molecules and oxygen and yields ATP. 2. Diagram for photosynthesis and respiration 3. What are redox reactions? What is the difference between reduction and oxidation reactions? Redox reactions are chemical reactions that transfer between reactants. In oxidation‚ a substance loses

Aerobic Respiration Do you know indulging in physical movements is associated with a chemical reaction? The process requires energy‚ which is yielded by aerobic respiration. Over here‚ respiration helps breaks down glucose (an energy source) into water‚ carbon dioxide and energy in form of ATP (adenosine triphosphate). The balanced cellular respiration equation is represented as: C6H12O6 + 6O2 → 6CO2+ 6H2O + Energy (36 ATPs) Anaerobic Respiration Due to overexercising

other half would not have anything to combine with to complete the DNA required to create a new cell. This would mean that reproduction of a new cell would not occur and the whole process would not be possible. Part 2: Photosynthesis and Cellular Respiration Matrix Complete the matrix. Use the following questions to aid in completion: • What is the purpose of this pathway? • Reactants: What does this reaction need to proceed? • Products: What is produced because of the

through cellular respiration. Cellular respiration involves four stages: glycolysis‚ the grooming phase‚ the citric acid cycle‚ and oxidative phosphorylation. The final two stages listed occur in the mitochondria. Part II 2. What are the consequences of a proton gradient and how could a gradient be used in the mitochondrion? List all the possibilities that come to mind. Protons have a strong positive charge. The electron transport chain that is part of the process of cellular respiration powers carrier

another. Electron aids in the gradual‚ stepwise release of the energy from oxidation‚ rather than rapid combustion. ATP power the activities that requires work --- one of the most which is movement. Explain the purpose of oxygen in respiration Without oxygen‚ cellular respiration could not occur because oxygen serves as the final electron acceptor in the electron transport system. The electron transport system would therefore not be available. Describe the structure of mitochondria A mitochondrion contains

and can be utilised by the body to stay alive. Oxygen is used to produce ATP for energy “the principle energy transferring molecule in living systems”(Anatomy and Physiology‚ Seeley‚ Stephens‚ Tate). Oxygen is essential to produce ATP. Internal respiration refers to the intracellular metabolic processes carried out within the mitochondria‚ which use O2 and produce CO2 during the derivation of energy from nutrient molecules. It involves the exchange of gases within the body. Blood vessels serve as

Introduction: Cytochrome c oxidase plays a vital role in cellular respiration by accepting e- from cytochrome c and transferring them to an acceptor oxygen molecule in the final step of electron transfer chain. Carbon monoxide and cyanide are few of the inhibitor of this enzyme. 4 Fe2+ -cyt c + 8H+ + O2 4 Fe3+ -cyt c + 2H2O + 4H+ [out] Cytochrome c oxidase locates to the inner membrane which separates the mitochondrial matrix from the intermembrane space.

Organisms are alive because of chemistry - Why we breathe oxygen‚ how we make energy‚ elimination of waste products‚ cellular respiration‚ etc. All of these are based on how living organisms use chemistry to live. Biological organisms have chemical compositions. Carbon is found in all living organisms. After that‚ because there are many chemical processes occuring in various
