2010-2023 Chapter 8 - Photosynthesis

Organisms that cannot make their own food and must obtain energy from the foods they eat are called

• autotrophs.
• thylakoids.
• heterotrophs.
• plants.

What are the three parts of an ATP molecule?

• adenine, thylakoids, stroma
• adenine, ribose, phosphate groups
• stroma, grana, chlorophyll
• NADH, NADPH, and FADH2

Energy is released from ATP when

• a phosphate group is added.
• ATP is exposed to sunlight.
• adenine bonds to ribose.
• a phosphate group is removed.

Which of the following is NOT a true statement about ATP?

• ATP consists of ribose, adenine, and phosphate.
• ADP forms when ATP releases energy.
• ATP provides energy for the mechanical functions of cells.
• Used ATP is discarded by the cell as waste.

Look at the figure above. All of the following are parts of an ADP molecule EXCEPT

• structure A.

• structure C.

• structure B.

• structure D.

Which structures shown in the figure above make up an ATP molecule?

• A and B

• A, B, C, and D

• A, B, and C

• C and D

In figure above, between which parts of the molecule must the bonds be broken to form an ADP molecule?

• A and B

• C and D

• B and C

• all of the above

Photosynthesis uses sunlight to convert water and carbon dioxide into

• oxygen.
• high-energy sugars and starches.
• ATP and oxygen.
• oxygen and high-energy sugars and starches.

Which of the following is(are) used in the overall reactions for photosynthesis?

• carbon dioxide
• light
• water
• All are used.

In the overall equation for photosynthesis, six molecules of carbon dioxide result in six molecules of

• glucose.
• oxygen.
• water.
• ATP.
