I believe the answer is D. don't take my word for it though I may be wrong
Answer:
The citric acid cycle is fundamental to produce the energy needed for aerobic cell metabolism, thereby mutations in the enzymes involved in this metabolic pathway would be lethal to the individual
Explanation:
In aerobic organisms, the citric acid cycle (also known as the Krebs cycle), is a key metabolic pathway used to remove electrons and uses them in the electron transport chain in order to generate adenosine triphosphate (ATP), the energy currency of the cell. The citric acid cycle depends on eight enzymes that oxidize acetyl-CoA into two molecules each of carbon dioxide (CO2) and water (H2O). Thus, the citric acid cycle is a series of chemical reactions that are key to breakdown carbohydrates, fats and proteins into CO2 and H2O in order to produce energy (ATP).
Brain is the organ that is most sensitive to the absence of glucose in the blood. The glucose is needed by the neurons in the brain to carry out their functions. The neurons when deprived of glucose, start to slow down and die out of exhaustion. The lack of glucose can cause symptoms of hypoglycemia, wherein a person starts to experience hallucinations and suffers from excruciating pain in the joints of the bones.
