Active transport requires the input of energy into a system so as to move solutes against their electrochemical and concentration gradients. WHich of the following is not one of the common ways to perform active transport?

A. NA+-Coupled

B. APT-driven

C. K+-coupled

D. light-driven

K+-coupled.

Explanation:

The transport of the solutes may occur along the concentration gradient or against the concentration gradient. Two main types of transport that occur in living organism are active process and passive process.

The passive transport do not require the energy for its transport whereas the active transport require energy. The K + coupled transport do not require any energy molecule for its transport and easily transfer by the leaky channel. Hence, the K+-coupled transport is not the common active transport.

Thus, the correct answer is option (C).
