Question

which of the following is another function of membrane proteins? a dna replication and synthesis b providing a source of energy to the cell c store energy for the cell for long - term use d moving molecules in and out of the cell

Explanation:

Membrane proteins are involved in transport functions such as facilitating the movement of molecules across the cell - membrane. DNA replication and synthesis is mainly related to enzymes and nucleic - acid related proteins, not membrane proteins. Providing energy to the cell is typically done by molecules like ATP and energy - storing molecules such as glycogen or fats, not membrane proteins. Storing energy for long - term use is the function of molecules like fats, not membrane proteins.

Answer:

D. Moving molecules in and out of the cell
