Metabolism: Fueling Cell Growth

True / False Questions

1)The change in free energy of a reaction varies.

 

2. Both glycolysis and the pentose phosphate pathway oxidize glucose to pyruvate.

 

3. Enzymes are changed by the reaction as they raise the activation energy.
4. Competitive inhibition usually involves both substrate and inhibitor competing for binding at the allosteric site.

 

 

5. The production of ATP via the electron transport system, in either eukaryotes or prokaryotes, requires the use of a membrane.

 

6. The TCA cycle must "turn twice" in order to complete the oxidation of one glucose molecule.

 

7. The terminal electron acceptor in aerobic respiration is water, which is broken down to hydrogen and oxygen.

 

8. In fermentation, the only ATP produced was during glycolysis and the fermentation reactions usually result in resetting the NADH to NAD.

 

9. H₂S and NH₃ may be used by some prokaryotes as energy sources.

 

10. The Calvin cycle produces 6 ATP for every 6 turns of the cycle.
