Question

Which is not true of active transport

• A. It is chemical process
• B. Energy is obtained from ATP
• C. Occurs through carrier molecules
• D. Not modified by enzymes.

Answer 1

The correct option is A It is chemical process

In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, against the concentration gradient. Active transport requires cellular energy to achieve this movement. During the process of active transport, a protein pump makes use of stored energy in the form of ATP, to move molecules. So it is not a chemical process.

Hence the correct answer is option A.
