ATP Energy Utilization in Biology

Steps:

• Identify processes 1, 2, and 3 from the question context (e.g., common ones like active transport, protein synthesis, DNA replication).
• Recall ATP as the energy currency hydrolyzed to ADP + Pi for endergonic reactions.
• Evaluate each process: active transport (1) requires ATP directly; muscle contraction (2) uses ATP for cross-bridge cycling; passive diffusion (3) needs no ATP.
• Select options including only ATP-dependent processes.

Not enough information: Processes 1, 2, and 3 are not specified.

Final answer: Not enough information.
