Energy required for active transport because it moves solutes against their concentration gradient.Group of answer choicesTrueFalse

Final Answer

True

Explanation

Active transport indeed requires energy because it is the process of moving solutes against their concentration gradient, which means that substances are being transported from areas of lower concentration to areas of higher concentration. This is contrary to passive transport mechanisms, where solutes move along their concentration gradient without the input of energy.

The energy for active transport typically comes from ATP (adenosine triphosphate) hydrolysis. There are various types of active transport, including primary active transport, which directly uses ATP to pump molecules, and secondary active transport, which uses the energy generated from the movement of one substance down its concentration gradient to move another substance against its gradient. Therefore, the statement is indeed true, as energy expenditure is a hallmark of active transport processes in biological systems.
