The Active Manager Paradox: High-Conviction Overweight Positions | CFA Institute Enterprising Investor

a
It requires energy
b
It moves substances down the concentration gradient
c
it does not ruse ATP
d
it moves material from high to low concentration

Answer 1

The correct statement about active transport is:

a. It requires energy.

Active transport is a process in which substances are moved against their concentration gradient (from an area of lower concentration to an area of higher concentration) and requires energy, typically in the form of ATP.

The other options are false:

• b. It moves substances down the concentration gradient - This is characteristic of passive transport, not active transport.
• c. it does not use ATP - Active transport requires energy, often derived from ATP.
• d. it moves material from high to low concentration - Active transport moves material from low to high concentration.
