Multiple Choice
Which molecule is the primary energy currency of all cells?
A
ATP (Adenosine Triphosphate)
B
NADH (Nicotinamide Adenine Dinucleotide)
C
FADH2 (Flavin Adenine Dinucleotide)
D
GTP (Guanosine Triphosphate)
Verified step by step guidance
1
Identify the role of each molecule listed in the options: ATP, NADH, FADH2, and GTP.
Understand that the primary energy currency of cells is the molecule that directly provides energy for most cellular processes.
Recognize that ATP (Adenosine Triphosphate) is known for its role in storing and transferring energy in cells.
Consider the functions of NADH and FADH2, which are primarily involved in electron transport and energy production in the form of ATP during cellular respiration.
Note that GTP (Guanosine Triphosphate) is similar to ATP but is less commonly used as the primary energy currency in cells.
