Detailed explanation-1: -Expert-Verified Answer. Enzyme synthesis cannot be a function performed by a membrane protein. Explanation: Membrane protein is found on the lipid bilayer that surrounds the cell.
Detailed explanation-2: -Answer and Explanation: The correct answer is E) store cellular nutrients. Cell membrane proteins cannot store cellular nutrients as they are far too small and located in an inconvenient location to actually distribute these nutrients throughout the cell.
Detailed explanation-3: -Membrane proteins serve a range of important functions that helps cells to communicate, maintain their shape, carry out changes triggered by chemical messengers, and transport and share material.
Detailed explanation-4: -The formation of proteins is not a function of the cell membrane.
Detailed explanation-5: -Membrane proteins can serve a variety of key functions: Junctions – Serve to connect and join two cells together. Enzymes – Fixing to membranes localises metabolic pathways. Transport – Responsible for facilitated diffusion and active transport.
