Biological Proccesses - Molecular Biology

3 important questions on Biological Proccesses - Molecular Biology

How many ATP can be generated by each carrier molecule?

1 NADH yields 3 ATP via oxid. phos. in the ETC
1 FADH2 yields 2 ATP via oxid. phos. in the ETC
1GTP yields 1 ATP via substrate level phos.

What order are alternative energy sources used up?

Other carohydrates, fats, proteins

These substances are first converted to glucose intermediates, and degraded in the glycolytic pathway/ Krebs cycle

Are enzyme catalyzed reactions reversible?

Usually yes

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
  • Never study anything twice again
  • Get the grades you hope for
  • 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
