In the presence of oxygen, the three-carbon compound pyruvate can be catabolized in the citric acid cycle. first, however, the pyruvate (1) loses a carbon, which is given off as a molecule of co₂, (2) is oxidized to form a two-carbon compound called acetate, and (3) is bonded to coenzyme a. which of the following sets of products result from these reactions?
a) acetyl coa, o₂, and atp.
b) acetyl coa, fadh₂, and co₂.
c) acetyl coa, fad, h₂, and co₂.
d) acetyl coa, nadh, h⁺, and co₂.
e) acetyl coa, nad⁺, atp, and co₂.

The best answer to the question: Which of the following sets of products result from these reactions, would be, D: acetyl CoA, NADH, H+ , and CO2.

Explanation:

The process of metabolism is a pretty complex series of steps whose proper functioning will depend entirely on the presence of different enzymes, coenzymes (which help enzymes in the transfer of electrons from one molecule to another) and other substances. In cells, especially in human cells, the process is usually in a one way direction and the purpose of the process is dual: break down molecules to acquire the energy stored in them (catabolism) and the building of new molecules (anabolism) through the use of the produced energy of catabolic pathways. This process is almost constant and it initiates with glycolisis, especially when we are talking about the metabolism of glucose. From glycolisis, we will receive two products: pyruvate and 2NADH. Then we start the second step, which is the citric acid cycle. From this one, at the end of all the chemical reactions, we will obtain: acetyl CoA due to the work of coenzyme A and coenzyme NAD over pyruvate, NADH as coenzyme NAD receives a hydrogen atom and then a free H+ as well as CO2.

well the answer is 2!
