Question

Carrier protein helped in a
(a) active absorption of ions
(b) passive ions absorption
(c) water absorption
(d) vaporization

Answer 1

Carrier protein helped in a passive ions absorption.

Option (b)

Explanation:

• Carrier proteins are the special proteins that help in the transport of ions or other solutes across the cell membrane.
• They bind the solutes on one end of the cell and delivers it to the other end of the cell through the cell membrane.
• The whole process is passive which means that there is no usage of energy in this transfer, and they work according to the electrochemical gradient.
• They generally transport the ions but they also transport organic molecules.
• The carrier proteins are highly selective and only binds with specific receptors.
