Which of the following best describes the power or driving force for active transport?
A) ATP
B) Pressure
C) DNA
D) H+

Question

Quizplus · Accepted Answer

Active transport requires energy input to move molecules against their concentration gradient. The most common form of energy used in active transport is ATP (adenosine triphosphate). ATP is hydrolyzed to ADP and Pi, releasing energy that is used by transport proteins to pump molecules across the cell membrane. Choices B, C, and D do not provide energy for active transport. Pressure may play a role in some types of transport, but it alone is not the driving force for active transport. DNA is the genetic material of the cell and does not play a direct role in active transport. H+ ions are involved in some types of transport, but they do not provide the energy for active transport.
