3. which molecule of energy is not required during passive transport?\natp\nh₂o\nco₂
Answer
Brief Explanations:
Passive transport is a type of membrane - transport that does not require energy input. ATP (adenosine triphosphate) is the energy - currency molecule of the cell. Passive transport occurs along a concentration gradient and does not need the energy provided by ATP. Water ($H_2O$) and carbon - dioxide ($CO_2$) can move across membranes by passive transport methods like diffusion, but they are not energy - providing molecules.
Answer:
A. ATP
