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.
Answer:
Biogenesis = <u>Life from life</u> : Spontaneous Generation = <u>Life from non-living things</u>
Explanation:
As an accurate statement of the difference between spontaneous generation and biogenesis:
Spontaneous generation that sometimes refers to "abiogenesis" is an idea that life comes from non-living things/components. Whereas biogenesis is a contemporary concept that life can only arise from another living thing.
Cell division, a baby of mice born from adult males and females, etc. are some examples of biogenesis. In contrast, there is no example of spontaneous generation. It remains a theoretical concept.
