Big Picture-
Overall, what are the reactants (what is needed) for cell respiration?
What are the products (what is produced)?
Why is photosynthesis and cell respiration considered opposite processes?
What is the source of energy in Photosynthesis? What is the energy created in cell respiration?
What organelle does photosynthesis occurs? What organelle does cell respiration occurs?
Glycolysis-
In the formation of pyruvate, it has to be oxidized. What is the reducing agent?
How many ATP’s are formed?
Identify the main difference between glucose and pyruvate.
Krebs Cycle-
Explain why the Krebs Cycle is a cycle.
Link reaction that takes place before the Krebs Cycle description:
What enzyme is required?
What is the end product?
What leaves the pyruvate molecule? In what form?
What is needed for the Krebs Cycle to begin?
Relationship to Glycolysis-
How many times does the Krebs Cycle take place per glucose molecule? Explain why?
Carbon characterization:
How many carbons are lost?
How many carbons does the molecule in the end of the Krebs Cycle have? In the beginning?
With the loss of carbon, what is formed?
Electron carrier identification:
Oxidation occurs throughout the Krebs Cycle. What are the types of electron carriers?
Where do the electron carriers carry the electrons to?
ATP production:
How many ATP molecules are produced per cycle of the Krebs Cycle?
How many per glucose?
Electron Transport Chain
Use the link below to answer the questions:
1. What type of transport causes the movement of hydrogen molecules across the membrane? Explain why?
2. ATP synthase is an enzyme that catalyzes the formation of ATP. What is the substrate? Explain the reactants and products of the reaction.
3. How do the electrons get transported down the membrane?
4. What is the purpose of NADH and FADH2? Where do they come from?
5. What is the purpose of oxygen? What molecule does it turn into after it is used?
