Chemical Energy and ATP

Which of the following statements is true for ALL cells?

• they use solar energy

• they use photosynthesis

• they use chemical energy

• they use chemosynthesis

Which phrase BEST DESCRIBES the function of ATP?

• store energy

• carry energy

• absorb energy

• convert energy

Making ATP requires energy. Where does the energy to make ATP come from?

• the conversion of ATP to ADP

• the use of chemicals from the environment to build sugars

• the addition of a phosphate group to ATP

• the breakdown of carbon-based molecules like carbs, lipids, or proteins

Energy is released from an ATP molecule for cellular processes when it:

• has a phosphate group removed

• stores an extra phosphate group

• converts a phosphate group to ADP

• produces a sugar molecule

Which of the following is a source of energy used in chemosynthesis?

• sunlight

• heat from hydrothermal vents

• chemical compounds

• amino acids
