Question

When does saturation occur?

(a) When molecules are moved by the use of vesicles

(b) When the energy from a high-energy bond is required to move molecules

(c) When a group of carrier proteins is operating at its maximum rate

(d) When a carrier molecule has the ability to transport only one molecule or a group of closely related molecules

I have been asked this question in examination.

I'd like to ask this question from Solute Transport across Membranes in chapter Lipids, Biological Membranes and Transport of Biochemistry

Answer 1

Right choice is (c) When a group of carrier proteins is operating at its maximum rate

Explanation: When a group of carrier proteins is operating at its maximum rate saturation occurs.
