The energy released by ATP hydrolysis (top) drives an endergonic reaction (right). This is called
- A
Independent reactions — each step proceeds without sharing energy intermediates
- B
Catalysis — an enzyme lowers activation energy so a single reaction can proceed
- Ccheck_circle
Energy coupling — exergonic ATP hydrolysis pays for endergonic reactions
- D
Diffusion — molecules move down a concentration gradient without any energy input
Explanation
Cells link favorable (ATP → ADP + Pᵢ) reactions with unfavorable ones to make the overall ΔG negative.
