Answer:
(D) a protein
Explanation:
The plasma membrane has proteins that are macromolecules responsible for the movement of large molecules in and out of the cell. If these proteins are damaged, this movement will be stopped.
In addition to acting preferentially on the transport mechanisms, organizing true tunnels that allow substances to pass into and out of the cell, these proteins function as membrane receptors, charged with receiving signals from substances that carry some message to the cell, favor the Adhesion of adjacent cells in a tissue, moreover, serve as the anchor point for the cytoskeleton.
Answer: Option B
Explanation:
The glucose is the basic unit of energy. It is absorbed by the cells of the body. The glucose that is taken inside the body by the means of food is utilized to gain energy.
The glucose that is absorbed from the food moves to interstitial spaces before going inside the cell.
100% of the glucose is transferred from the interstitial spaces of the cell to the inside of the cell.
This is because more amount of the glucose is still outside the cell as it is absorbed completely.
