Question

The movement of ions against the concentration gradient will be:

• A. Active transport
• B. Osmosis
• C. Diffusion
• D. All

Answer 1

Answer: (A)

Active transport

Answer 2

The movement of ions against the concentration gradient is typically accomplished through Active transport. Active transport processes use energy (usually ATP) to pump ions or molecules across a cell membrane against their concentration gradient, from areas of lower concentration to areas of higher concentration. This process is essential for maintaining ion gradients and performing various physiological functions.

So, the correct option is (A): Active transport
