Explanation:

Reptiles referred to as cold blooded uses the environment to regulate their body temperature. That's an excellent reason why they like crawling on the ground to get warmth in a cold environment.

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.
