How many nadh molecules are created from the pyruvate molecules that enter the Krebs cycle?

Three molecules of NADH is produced from every molecule of pyruvate that enters the Krebs cycle.

Explanation: Pyruvate produced from glycolysis is broken down to Acetyl CoA which then enters the Krebs cycle. In Krebs cycle, each molecule of acetyl CoA yields one molecule of GTP (ATP), one molecule of FADH2 and three molecules of NADH. The main purpose of Krebs cycle is to generate NADH needed in the cells. Krebs cycle is a series of eight enzyme catalyzed reactions which oxidizes the Acetyl CoA produced from pyruvate. The NADH molecules are produced by dehydrogenase enzymes:

1). Isocitrate dehydrogenase which converts isocitrate to alpha ketoglutarate.

2). Alpha ketoglutarate dehydrogenase which converts alpha ketoglutarate to succinyl CoA.

3). Malate dehydrogenase which converts malate to oxaloacete.

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)
