Question

Primary and secondary active transports, both.

• A. Generate ATP
• B. Use ATP
• C. Can move solutes against their concentration gradients
• D. Include passive movement of glucose molecule

Answer 1

The correct option is C Can move solutes against their concentration gradients

Active transport is the movement of molecules across a cell membrane from a region of their lower concentration to a region of their higher concentration in the direction against the concentration gradient. The only difference being, in primary active transport, the energy is derived directly from the breakdown of ATP. In the secondary active transport, the energy is derived secondarily from the energy that has been stored in the form of ionic concentration differences between the two sides of a membrane.

Thus, the correct answer is option (C).
