What early process will occur w/ or w/o O2?
What happens during the above process?
What determines which pathway pyruvate will take?
Krebâs Cycle:
1. Summarize the 8 stages of the Krebs cycle including what carbon molecule is produced at each step, when CO2is released, when NADH and FADH2get produced, and when ATP is produced.
2. Why is it important to end up with the molecule that starts the process? What is that molecule?
3. How many turns of the cycle are there per glucose molecule?
4. What is the major goal of the Krebs Cycle? What must be generated during this cycle to allow the ETC to occur?
