Question

The model illustrates a process by which a substance is taken up by a cell. Which statements describe the process? Select the correct answer. a. The cell wall shown in the model is changed into a cell membrane. b. The process shown in the model requires energy from the cell. c. The cell membrane in the model remains intact throughout the process. d. The model shows the process of facilitated diffusion.

Answer 1

Answer:

The process shown in the model requires energy from the cell.

Explanation:

Active transport refers to the movement of materials across the cell membrane against concentration gradient.

The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
