Answer
The examples of active transport are exocytosis and endocytosis.
Explanation
## Step 1: Understand the concept of active transport. Active transport is a process that involves the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration. This process requires energy, usually in the form of ATP (adenosine triphosphate).## Step 2: Identify the options that are examples of active transport. Active transport includes processes such as exocytosis, endocytosis, and the sodium-potassium pump. ## Step 3: Explain each process. Exocytosis is a process where cells transport molecules out of the cell by expelling them in an energy-dependent process. Endocytosis is a process where cells absorb molecules by engulfing them, which also requires energy. Facilitated diffusion, simple diffusion, and osmosis are examples of passive transport, not active transport, because they do not require energy.
