Cellular Respiration and Photosynthesis

Which of the following statements is true for all cells?

• They use solar energy.

• They use photosynthesis

• They use chemical energy.

• They use chemosynthesis

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.

Where does the chemical energy to produce 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 glucose, into smaller molecules

Which of the following statements best describes the process of photosynthesis?

• Plants use oxygen to make simple sugars.

• Chlorophyll builds sugars in the thylakoid membrane.

• Light breaks down water molecules and releases carbon dioxide.

• Chloroplasts absorb sunlight and produces glucose.

The main light-absorbing molecules found in plant leaves are called

• chloroplasts

• thylakoids

• chlorophyll.

• grana.

The function of the light-dependent reactions is to

• build sugars

• capture and transfer energy.

• release carbon dioxide.

• form water molecules.

Which of the following types of organisms uses cellular respiration for their cellular energy needs?

• eukaryotes

• plants only

• animals only

• prokaryotes

Which process breaks down sugars to make ATP when oxygen is present?

• anaerobic respiration

• cellular respiration

• glycolysis

• photosynthesis

The part of cellular respiration in which glucose is broken down is called

• photosynthesis

• aerobic respiration

• electron transport.

• glycolysis.

The light-independent reactions of photosynthesis need

• carbon dioxide.

• oxygen.

• sunlight

• cellulose.
