WORTH 30 POINTS!!!!

FOR THIS QUESTION YOU MUST INCLUDE THE FOLLOWING:

- Claim/ statement

- Evidence (data observations from science facts or diagram models)

- Reasoning (connect the evidence to the claim and diss use the relationship between the two)

There is a small amount of NAD+ made by a cell. If oxygen is not present, pyruvate becomes the final electron acceptor thus allowing for the recycling of NAD+.

QUESTION: EXPLAIN how using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.

Answer 1

Answer: Claim: Using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+.

Evidence: In the absence of oxygen, pyruvate accepts electrons from NADH to become lactate or ethanol. This reaction regenerates NAD+, which can then be used in glycolysis to produce more ATP.

Reasoning: During glycolysis, NAD+ is converted to NADH when it accepts electrons from glucose. Without the recycling of NAD+, glycolysis would stop due to a lack of available NAD+. However, in the absence of oxygen, pyruvate can accept electrons from NADH and regenerate NAD+. This allows for the continuation of glycolysis, which is necessary for the production of ATP. Therefore, using pyruvate as the final electron acceptor in an anaerobic process allows for the recycling of NAD+ and the continuation of ATP production through glycolysis.
