Why do cells need to generate ATP?
A
To store and transfer energy for cellular processes
B
To facilitate the transport of oxygen
C
To synthesize DNA and RNA
D
To provide structural support to the cell
Verified step by step guidance1
Understand that ATP (adenosine triphosphate) is the primary energy currency of the cell, used to store and transfer energy for various cellular processes.
Recognize that cells require energy to perform essential functions such as muscle contraction, nerve impulse propagation, and chemical synthesis.
Identify that ATP is involved in active transport mechanisms, where it provides the energy needed to move molecules across cell membranes against their concentration gradient.
Acknowledge that ATP is crucial for the synthesis of macromolecules, including DNA and RNA, by providing the necessary energy for the formation of chemical bonds.
Note that while ATP is vital for energy transfer, it does not directly provide structural support to the cell; this role is fulfilled by other cellular components like the cytoskeleton.
