Answer:
D. Citric Acid Cycle.
Step-by-step explanation:
The Krebs Cycle is also known as the Citric Acid Cycle. This cycle is a crucial part of cellular respiration, a series of chemical reactions that occur in the mitochondria of cells to generate energy in the form of adenosine triphosphate (ATP). The cycle involves a sequence of enzymatic reactions that convert acetyl-CoA, derived from carbohydrates, fats, and proteins, into energy-rich molecules like ATP, NADH, and FADH2.
The name "Citric Acid Cycle" is derived from the fact that the cycle begins with the reaction of acetyl-CoA and oxaloacetate to form citric acid (also known as citrate). The cycle then proceeds through several intermediate compounds, ultimately leading to the regeneration of oxaloacetate, which can enter the cycle again to continue the process.
The alternative options (A, B, and C) do not accurately represent the Krebs Cycle or its functions. The cycle is not related to the mitotic or meiotic cycles involved in cell division, nor is it part of the replicative cycle associated with DNA replication. Instead, the correct name for this metabolic pathway is the Citric Acid Cycle due to the presence of citric acid as an intermediate compound.
