Question

1. which of the following are types of active transport? select two correct answers. facilitated diffusion endocytosis sodium - potassium pump simple diffusion osmosis

Explanation:

Active transport requires energy to move substances against their concentration gradient. Endocytosis is a process where cells engulf substances by forming vesicles, and the sodium - potassium pump uses ATP to move sodium and potassium ions across the cell membrane. Facilitated diffusion, simple diffusion, and osmosis are passive transport processes that do not require energy input.

Answer:

B. endocytosis, C. sodium - potassium pump
