ATP and Energy Transfer Concepts

What is ATP often called in cells?

• A building block

• The energy currency

• A waste product

• A type of sugar

What happens to energy when ATP changes into ADP and a phosphate group?

• Energy is absorbed

• Energy is released

• Energy stays the same

• Energy is created

Why doesn't ATP break down all the time by itself, even though it's a natural process?

• It needs to be very cold

• It needs to overcome a small energy hill

• It needs to be mixed with sugar

• It needs to be in the dark

What do special helpers called ATPases do to help ATP break down?

• They make the reaction need more energy

• They slow down the reaction

• They lower the energy needed for the reaction

• They build new ATP molecules
