Chemical Energy & ATP — Interactive
ATP (adenosine triphosphate) stores chemical energy in its phosphate bonds. When the terminal phosphate is removed (ATP → ADP + Pi), energy is released to power cellular work such as active transport, protein synthesis, and muscle contraction. Cells regenerate ATP mainly from the chemical energy in food during cellular respiration. In plants, light-dependent reactions of photosynthesis also produce ATP.
Q1 ATP → ADP + Pi releases energy when the γ phosphate is removed. Choose the term for this reaction:
Q2 Where is most ATP generated during cellular respiration?
Q3 (Multi‑select) Which processes use ATP? (Select all that apply.)
Q4 In photosynthesis, ATP is produced during the light‑dependent reactions and then used to power the Calvin cycle. What is the immediate source of energy that drives ATP synthase in chloroplasts?
Q5 Match processes to Produces ATP vs Uses ATP.
