(PLEASE HELP will give first correct answer brainliest!!) Which option correctly describes glucose catabolism?

1. Glucose is broken down in glycolysis, yielding two ATP molecules; after the Krebs cycle, 34 molecules of ATP are formed in ETS reactions.

2. Glucose is broken down in glycolysis, yielding pyruvic acid; after the Krebs cycle, two molecules of ATP are formed in ETS reactions.

3. Glucose is broken down in glycolysis, yielding two ATP; after the Krebs cycle, NADH and FADH2 are formed, yielding NAD+ and FAD in ETS reactions.

4. Glucose is broken down in glycolysis, yielding pyruvic acid; after the Krebs cycle, NADH and FADH2 are formed, yielding 34 ADP in ETS reactions.
