In cellular respiration, energy is trapped in the form of ATP, which is used for cellular work, and acts as a “currency” for energy transfers within a cell. Which everyday item functions in a way similar to ATP?

• An electric motor because it produces electrical energy from a fuel source

• A rechargeable battery because it can store energy and then release it.

• An electric motor because the charge difference spins the ATP, which allows it to do cellular work.

• A pump, because it moves molecules from onside of a membrane to another.

Which one of the following describes the process of aerobic cellular respiration?

• A process of energy conversion that captures light energy and transforms it into chemical energy.

• A process of energy transfer that converts water into water vapor.

• A process of energy conversion that releases energy from food in the presence of oxygen, forming new compounds.

• A process that uses nitrogen molecules from the air to make nitrogenous compounds in living things.
