Question

Assertion (A): Active transport is uphill transport.

Reason (R): Active transport uses energy to pump molecules against the concentration gradient.

• A. Both A & R are true and R explains A
• B. Both A & R are true and R doesn't explain A
• C. A is true and R is false
• D. Both A & R are false

Answer 1

The correct option is A

Both A & R are true and R explains A

Active transport uses energy to pump molecules against concentration gradient i.e from the region of lower concentration to higher concentration and hence the transport is referred as uphill transport.
