Passive absorption of minerals depends on
A
temperature
B
temperature and metabolic inhibitor
C
metabolic inhibitor
D
humidity.
Answer
temperature
Explanation
Solution
Rate of salt absorption increases when temperature increases but to a certain limit as salt absorption is inhibited at higher temperature because certain enzymes are not active at higher temperature and carriers are not synthesised. These carriers are required for active transport of salts from outer space in inner space. Rate of diffusion of ions and molecules increases at enhanced temperature due to their increased kinetic activity. Thus passive salt absorption will increase.
