who knows

explanation:

i am positive it is c. condensing but i may be wrong

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

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.
