What energy-carrying molecule is produced during cellular respiration for cellular use?

Explanation:
In cellular respiration, the energy released from glucose is stored in ATP, the molecule cells use for immediate work. NADH and FADH2 act as electron carriers, delivering energy to the mitochondrial electron transport chain. There, the flow of electrons powers ATP synthase to convert ADP and inorganic phosphate into ATP. This ATP is then available to power processes like muscle contraction, active transport, and biosynthesis. While NADH and FADH2 are essential for capturing and delivering energy, they are not used directly as the cell’s energy currency; ATP is. GTP appears in a few steps, but ATP is the primary energy-carrying molecule produced for cellular use.
