2. They are complex molecules made from smaller molecules.

Explanation:

each biomolecule is made up of monomers or building blocks .

answer: c

explanation:

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
