Answer:
E. All of the above
Explanation:
The cell cycle refers to the orderly series of events that make new daughter cells by dividing the existing cells. The cell cycle is required to produce new cells during growth and development, to replace the old and damaged cells, and to repair the tissue by adding the new cells. If the existing cells do not enter the cell cycle, new cells would not be formed to be added to the tissues of the organisms.
However, the cell cycle is regulated at several checkpoints to ensure that a cell enters the process only when the new cells are required by the body and the process is stopped once the required number of new cells are formed. Any deviation from the regulation of the cell cycle may make the cells to enter the uncontrolled cell division. It may even lead to cancer where the cells divide without any control and produce malignant tumors.
Here one of the answer Red Cedar Tree
Answer: To
compensate for low concentrations of carbohydrates, the body hydrolyzes TAGs to
free fatty acids and glycerol, the latter of which is provided in ample supply
to feed the -citric acid cycle.
<span>When the body is
under starvation condition, low concentration of carbohydrates occurs, then the
body hydrolyzes triacylglycerols to fatty
acids and ketone bodies. Moreover, the acetyl CoA cannot be transformed into pyruvate so fatty
acids cannot be converted into glucose. The other potential source of glucose
is amino acids but this process is inherently inefficient and weakens
the body so protein must be preserve.</span>
