<h3><u>Answer;</u></h3>
D. Form part of the cell membrane
<h3><u>Explanation;</u></h3>
- Fats are among the three major nutrients in food, other being proteins and carbohydrates.
- The body uses fat as a source of fuels, and fat is the major storage form of energy in the body.
- Fat has other function such as insulation and protection of vital organs such as the heart and the lungs.
- Fats also acts as chemical messengers helping proteins carry out their functions. Fats are also major components of the cell membrane which regulates materials in and out of the cell.
It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.
<h3>Why the discovery of cyclins and cdks was enabled?</h3>
The discovery of cyclins and cdks was enabled by studying frog eggs that divided synchronously after fertilization; extracts from the embryos were thus representative of the cell-cycle stage at which the extract was made.
Researchers have devised means to synchronize asynchronous populations of cultured cells. for example, serum starvation deprives cells of mitogens and blocks cells in the g0/g1 phase of the cell cycle.
Therefore, It is often useful for scientists to study a population of cells that are all at the same stage of the cell cycle.
