Which are highly specialized membrane proteins that modify the cell's response to its environment?

a. transport proteins
b. enzymes
c. receptors
d. peroxisomes

Option A and C.

Transport and receptor protein.

Explanation:

Membrane protein are pathway protein that control the flow of materials and information across the cell.

These proteins modify the cell response to the environment. Examples of membrane proteins are receptor and transport protein.

Receptor are protein that receive signal in the cell.

Transport protein are responsible for movement of ions,molecules or materials across the cell and its environment. These two proteins are responsible for modifying cell response to it's environment.
