Final answer:
The statement is false. While glucose is a primary source of energy for the body, the main source of energy is ATP (adenosine triphosphate). (option B is the correct answer).
Step-by-step explanation:
Glucose is converted into ATP through cellular respiration, a process that occurs in the mitochondria of cells. During cellular respiration, glucose undergoes a series of chemical reactions, ultimately producing ATP. ATP is the molecule that carries energy within cells and provides the necessary fuel for various cellular activities.
Therefore, while glucose is an essential precursor for ATP production, it is not the direct main source of energy; rather, ATP serves as the immediate energy currency for cellular functions.
Understanding the hierarchy of energy molecules in cellular processes is crucial. While glucose is a vital component, ATP serves as the primary energy carrier within cells, making the statement false. This distinction is essential for a comprehensive understanding of cellular energy metabolism.
