In the context of activated carriers, which molecule is considered the primary energy currency of the cell?
A
ATP (adenosine triphosphate)
B
FADH
C
NADH
D
GTP (guanosine triphosphate)
Verified step by step guidance1
Understand the concept of activated carriers: these are molecules that store and transfer energy within the cell to drive various biochemical reactions.
Recall that the primary energy currency of the cell is a molecule that can release energy quickly and efficiently when its high-energy phosphate bonds are broken.
Identify ATP (adenosine triphosphate) as the molecule with three phosphate groups, where the bonds between these phosphates store significant energy.
Recognize that when ATP is hydrolyzed (loses a phosphate group), it releases energy that can be used to power cellular processes.
Compare ATP with other molecules listed (FADH2, NADH, GTP) and note that while they are important activated carriers, ATP is the main molecule universally used as the primary energy currency in cells.
