Which of these statements about osmosis and active transport is NOT correct? A) Both endocytosis and active transport require cell energy.

B) Osmosis requires cell energy while active transport does not.

C) Neither faciliated diffusion nor osmosis requires cell energy.

D) Diffusion of gases and other small molecules requires no energy on part of the cell.

Answers

Answer:

The correct answer would be option B.

Osmosis refers to the passive movement of water down the concentration gradient across a semi-permeable membrane. Thus, it does not require cell energy.

In contrast, active transport requires cell energy as it transports substances across the cell membrane against the concentration gradient, that is, from the region of low concentration to the region of high concentration.

It usually gets energy by ATP hydrolysis.

Examples may include sodium-potassium pump, GLUT transporters in intestinal cells et cetera.
B)bcz osmosis donot require energy but active transport does require energy
