The following substrate is completely oxidized to CO2 by a cellular homogenate containing all necessary enzymes and coenzymes . It is assumed that the glycolysis, the citric acid cycle and oxidative phosphorylation are fully active and that the glycerol-3-phosphate shuttle is functional. What is the net gain of ATP molecules after the complete degradation of one Glyceraldehyde 3-phosphate molecule

The correct answer is - 19 ATP.

Explanation:

One molecule of dihydroxyacetone phosphate fully oxidizes and generate 19 molecules of ATP by the following stochiometry

Direct ATP- 2

ATP from NADH ( 5X3)= 15

ATP from GTP 1

ATP from FADH2 1 or 1.5

Total 19 or 19.5

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
