Give me some examples about ways our body uses ATP?

The body uses ATP to power every cellular process in your body.

Can you think of some examples of ways that your body uses energy?
Those would all answer this question.

Post some here and I'll try to let you know if they are right.

Some hints: ATP is used by many enzymes (e.g. DNA polymerases, topoisomerases), molecular motors, membrane channels. It is even used for transmitting signals.

ATP is needed for active transport ;)
