Transport of glucose into the cell with the help of insulin is an example of:
Correct answer: B. Facilitated diffusion
- A. Osmosis
- B. Facilitated diffusion
- C. Active transport
- D. Endocytosis
Explanation
Glucose is transported by transporter proteins which act as channels or transporters that facilitate the movement of glucose across the cell membrane. Facilitated diffusion is a passive transport mechanism that does not require the expenditure of energy. It relies on the concentration gradient and the presence of specific transport proteins to move molecules across the cell membrane.
