Question

Which of the following statements is true about transport?

a. Active transport does not require energy, passive transport does.
b. Examples of passive transport are exocytosis, endocytosis, and sodium-potassium pumps.
c. Active transport requires energy and goes up the concentration gradient.

Answer 1

Active transport requires energy to move substances across the plasma membrane.

Step-by-step explanation:

Active transport requires energy to move substances across the plasma membrane, often because the substances are moving from an area of lower concentration to an area of higher concentration or because of their large size. Two examples of active transport are the sodium-potassium pump and vesicle transport.

Answer 2

I'm pretty sure the answer is C. Sorry if I'm wrong!
