Question

In case, respiration is inhibited by some inhibitor, the nonosmotic active absorption of water will

• A. Decrease
• B. Increase
• C. Remain same
• D. None of the above

Answer 1

Answer: (A)

Decrease

Osmosis is transport of solvent or water across semi permeable membrane along the concentration gradient. Osmosis is a type of passive transport and does not involves energy input. Active transport occurs against the concentration gradient and requires input of energy. The energy comes from respiratory activity in the cell. If respiration is inhibited, active transport will decrease.
