How do regulatory proteins of the cell cycle maintain homeostasis? the regulatory proteins control the cycle by signaling the cell to either or delay the next phase of the cycle. it seems that the proteins act as transporters in the homeostasis process.

The regulatory proteins control the cycle by signaling the cell to either or delay the next phase of the cycle.

Explanation:

Cell cycle regulatory proteins help maintain homeostasis because they control the cycle by signaling the cell to or delay the next phase of the cycle. Thus these proteins prevent the imbalance of molecules in the body and as we know homeostasis seeks to maintain balance in the body.

The cell cycle can stop at certain points and only advance if certain conditions are met, such as the presence of an adequate amount of nutrients, when the cell reaches certain dimensions, or when the cell needs to delay or stop a certain phase of a metabolic process. The regulation of the cell cycle is done through the regulatory proteins.

endocrine glands secrete hormones into the blood stream near them; the hormones then travel in our bloodstream until it reaches its destination, called a target cell, in distance parts of the body. in the target tissue, hormones lock onto the target’s plasma membrane, called the receptor site.
