Answer:
The fact that it reveals is that:
Epinephrine binds to the receptor tyrosine kinase on the cell membrane and does not act on glycogen phosphorylase.
Explanation:
In cellular respiration, epinephrine is a neurotransmitter and a plasma membrane hormone receptor. It is not a lipid-derived hormone, but rather an amino acid-derived hormone. As a result, they are unable to pass through the plasma membrane of cells. They bind to receptors on the outer surface of the plasma membrane through plasma membrane hormone receptors (receptor's tyrosine kinase of the cell membrane) because they are lipid insoluble hormones.
Unlike steroid hormones, lipid insoluble hormones (epinephrine) do not directly influence glycogen phosphorylase or the target cell because they cannot enter the cell and operate directly on DNA. The activation of a signaling pathway occurs when these hormones attach to a cell surface receptor; this activates intracellular activity and performs the hormone's specific effects. Nothing crosses through the cell membrane in this fashion; the hormone that binds at the cell's surface stays at the cell's surface, while the intracellular component stays within the cell.
Answer:
Plant produces food material in the process of photosynthesis in the leaves. The food that is produced in the form of glucose (sugar) is transported from the leaves to other parts of the plants such as roots, stem and seeds with the help of water. When the glucose reaches to the storage part it is stored in the form of starch.
For example, in carrot and potato food is stored in roots while in sugar cane the food is stored in the stem.

Whereas an onion epidermal cell has a cell wall, a human cheek cell does not. Instead, a semi-permeable membrane surrounds the cytoplasm of the cheek cell. While there are chloroplasts present in onion cells, they are absent in cheek cells. </span>
