1. Why are anabolic reactions that require energy always linked with the hydrolysis of a high energy compound like ATP? 2. Why is the conversion of NAD+ to NADH and H+ a reduction?

1. Overall, what do glycolysis, the Krebs cycle, and electron transport do? (Know starting materials and products.) Explain very briefly how energy stored in glucose is converted into energy stored in ATP. Where are oxygen, carbon dioxide, glucose, water, and ATP involved, and how do they relate to each other? Where is the most number of ATP produced? 2. Account for the 6 Carbons in glucose. In other words where does the 6 carbons in glucose end up 3. When is fermentation used instead of cellular respiration? How does this apply to humans? Know the industrial uses of fermentation 4. What is ATP synthase do? Where is it located? 5. How are oxygen and carbon dioxide related to the function of the mitochondria? Why do we REALLY need to breathe? (Hint: where does CO2 come from? Where is O2 used?) 6. Know how cyanide stops cellular respiration

5. Which of the following pathways will use coenzyme A during aerobic cellular respiration? electron transport system pyruvate oxidation glycolysis Krebs cycle

1. Name the metabolic process 2. Name the stage of metabolism this gas is involved in 3. Describe exactly how is it involved 4. The redox of the reaction 1) Why do humans breath in O2? Why do humans breath out CO2? Why do plants take in CO2? Why do plants take in H2O? Why do plants give off O2?
