Question

What is one way a protein receptor affects the functioning of a cell?

Protein receptors help the cell obtain necessary materials by leaving the cell and binding to molecules; the receptors then carry the attached molecules back through the cell membrane into the cell.

Protein receptors bind to other cells in the body to form a temporary connection; pieces of DNA can pass through this connection, allowing genetic information to be shared between cells.

Protein receptors help the cell perform osmosis by actively transporting water molecules; this is necessary because water molecules cannot easily diffuse through the hydrophobic region of the cell membrane's lipid bilayer.

Protein receptors help the cell perform endocytosis by binding to proteins and molecules outside the cell; this triggers a response that causes the cell membrane to take substances into the cell.

Answer 1

The correct way a protein receptor affects the functioning of a cell is:

Protein receptors help the cell perform endocytosis by binding to proteins and molecules outside the cell; this triggers a response that causes the cell membrane to take substances into the cell.

This mechanism is important as it allows the cell to internalize various substances, including nutrients and signaling molecules, thereby contributing to cellular communication and metabolism.
