Answer: D. some components of the cycle are used as building blocks for certain anabolic pathways.
Explanation:
The citric acid cycle or Kreb's cycle is the part of the cellular respiration. It is a sequence of chemical reaction which is used by all the aerobic organisms so as to store energy by the process of acetyl CoA oxidation derived by the process of fats, proteins and carbohydrates into forms like carbon dioxide and adenosine triphosphate (ATP).
The acetyl CoA is used in the process of synthesis of fatty acids. The citrate is used for the synthesis of cholestrol. The oxaloacetate and alpha ketogluterate are used for the synthesis of aminoacids. Succinyl CoA is used for the synthesis of poryphrins and fatty acids.
The Krebs cycle is the process that is responsible for producing CO2 and releasing usable energy for the cell, therefore some components of the cycle are used as building blocks for certain anabolic pathways.
What is Krebs cycle?
It is a metabolic pathway that has the objective of providing the cell with an important source of energy in the form of ATP (adenosine triphosphate).
Characteristics of Krebs cycle
- Glycolysis and the Krebs cycle are considered the axis metabolic pathways, they participate in the degradation of almost all the components of the cell.
- It provides the reducing power and building materials, in addition to ATP, for all biosynthetic sequences in the cell and energy for other activities.
Therefore, we can conclude that the Krebs cycle is part of cellular respiration in all aerobic cells, performs the oxidation of carbohydrates, fatty acids and amino acids, some components of the cycle are used as building blocks for certain anabolic pathways.
