Question

Mineral absorption is mainly an active process'. Justify.
​

Answer 1

Answer:

• Active absorption is the absorption of minerals against the concentration gradient.

• This process requires the expenditure of metabolic energy.

• Higher rate of respiration increases salt accumulation inside the cell.

• Respiratory inhibitors reduce the rate of mineral absorption.

• If oxygen content in the medium is less, then the rate of mineral absorption decreases.

• This explains that mineral absorption is mainly an active process.

Answer 2

Active Mineral Absorption. Active mineral absorption is an active process and thus it requires the expenditure of metabolic energy (ATP). Active mineral absorption can occur both along and against the concentration gradient by osmosis or through special carrier proteins in the plasma membrane.
