Question

Place the following in the correct order as they occur in CELL RESPIRATION.

Answer 1

1. Electrons and h+ ions pop off and are picked up by NADH.
2. 1 C is stripped from 3-C PGA and makes Co2.
3. Coenzyme A attaches to 2-C molecule making Acetyl Co-A.
4. Resulting 3 C molecule is stabilized BEFORE entering the mitochondria.
5. Acetyl Co-A enters mitochondria and drops off 2-C molecules.
6. In cytosol, 6-C glucose and 2 ATP split into two 3-C molecules (glycolysis).
7. 2-C molecule combines with 4-C molecule and breaks into two 3-C molecules
8. Krebs cycle spins twice; each time stripping 1 carbon to make Co2 as a by-product.
9. With each cycle of Krebs, electrons and H+ ions pop off, are picked up by NADH and FADH2 and taken to ETC
10. 4 molecules of ATP are generated.
