Cellular Respiration Guided Reading For Beau

AP Biology Name Nathan Sandidge Cellular Respiration Guided Reading Assignment Define the two catabolic pathways: a. Fermentation Fermentation is cells release some excess energy in anaerobic conditions. b. Cellular respiration Cellular respiration is when the pyruvic acids are broken down into just CO2, and energy is released. Converts energy found from light photons into usable energy to then convert NADP+ to NADPH and finally into ATP. 2. Use the following terms correctly in a sentence: redox reactions, oxidation, reduction, reducing agent and oxidizing agent.

3. Why is being “reduced” equivalent to having a greater potential energy?

4. In cellular respiration, what is being oxidized and what is being reduced? 5. Why are electron transport chains an advantage to living systems? 6. What are the three stages of aerobic cellular respiration? 7. What is substrate-level phosphorylation?
