Question

What would be the most possible anomaly when oxaloacetic acid is being continuously removed from the cell as soon as it is formed?

A There will be no formation of NADH+H+ in the cell B Krebs cycle will not occur in the cell C There will be the formation of only 20 ATP from the Krebs cycle D Oxidative phosphorylation will not occur in mitochondria

Answer 1

Answer:

A colorless crystalline dicarboxylic acid that is formed by oxidation of malic acid in the Krebs cycle and by transamination from aspartic acid. It is important in the metabolism of carbohydrates and in the synthesis of amino acids.

Answer 2

Answer:

B) Krebs cycle will not occur in the cell is the correct answer.

Explanation:

What is Kreb's cycle:

• The tricarboxylic acid (TCA) cycle, commonly known as the Kreb's or citric acid cycle, is the primary source of energy for cells and is an essential component of aerobic respiration.
• The Kreb's cycle is a multistep cyclic pathway that begins when oxaloacetic acid binds to acetyl co enzyme-A.
• Citric acid (6C) is the cycle's first product.
• Half of the intermediates that the cycle relies on are also the starting points for pathways that lead to key chemicals such fatty acids, amino acids, and porphyrins. If any of these intermediates are misdirected in this way, the cycle's integrity is destroyed, and the cycle ceases to function.

What happens when oxaloacetic acid is removed:

• So if oxaloacetic acid will be entirely eliminated from the cell as it is generated, it will not be available in cell.
• Kreb's cycle will not occur in such a case.
