Based on Concept 8.3, what is the primary role of ATP in cellular work?

  • A: To directly synthesize organic molecules from CO2.
  • B: To act as an enzyme in metabolic reactions.
  • C: To power cellular work by coupling exergonic reactions to endergonic reactions.
  • D: To serve as a structural component of the cell membrane.

Explanation

Concept 8.3 is titled 'ATP powers cellular work by coupling exergonic reactions to endergonic reactions'. This precisely describes ATP's primary function as an energy coupler.
