Which molecule is commonly known as the energy currency of the cell?
A
DNA (Deoxyribonucleic Acid)
B
RNA (Ribonucleic Acid)
C
NADH (Nicotinamide Adenine Dinucleotide)
D
ATP (Adenosine Triphosphate)
Verified step by step guidance1
Identify the role of each molecule listed in the options: DNA, RNA, NADH, and ATP.
Understand that DNA and RNA are nucleic acids involved in genetic information storage and transfer, not directly in energy transfer.
Recognize that NADH is a coenzyme involved in redox reactions and electron transport, contributing to energy production but not directly serving as the primary energy currency.
Learn that ATP (Adenosine Triphosphate) is the molecule that stores and transfers energy within cells, often referred to as the 'energy currency' of the cell.
Conclude that ATP is the correct answer because it directly provides energy for cellular processes through the hydrolysis of its phosphate bonds.
