ATP vs. ADP

Which molecule supplies the energy for cellular functions?

• ATP

• DNA

• oxygen

• water

Which of the following is produced (along with ATP) when sugar is digested in an animal cell?

• carbon dioxide

• chlorophyll

• oxygen

• sunlight

Photosynthesis includes processes that require light and processes that do not. Which statement best explains why adenosine triphosphate (ATP) is used in both processes?

• ATP is a building block of sugars (a monomer of sugars) and stores energy in plant cells.

• ATP collects chemical energy from plant cells and produces light energy to build sugars.

• ATP stores energy that plant cells absorb from light and releases the energy when it is needed to produce sugars.

• ATP is an enzyme that increases the rate at which sugars are made and reduces the amount of energy that plant cells need.

What is the function of ATP in living things?

• provides energy for cells

• provides structure in the nucleus

• provides structure for the cytoplasm

• cells have very little use for ir.

Which structures shown in the Figure make up the ADP molecule?

• A and B
