Chapter 4 Test Review

What is the name of the process that breaks glucose down into the pyruvate that is used in cellular respiration?

• fermentation
• electron transport
• glycolysis
• chemosynthesis

The aerobic stages of cellular respiration takes place in the

• cell membrane
• mitochondria
• cytoplasm
• grana

Which process is best represented by the chemical equation C6H12O6 + 6O2 → 6CO2 + 6H2O +ATP

• cellular respiration
• photosynthesis
• glycolysis
• fermentation

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 the source of energy used in chemosynthesis?

• sunlight
• heat
• chemicals
• amino acids

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 create glucose

The function of the light-dependent reactions is to

• build sugars.
• capture and transfer energy.
• release carbon dioxide.
• form water molecules.

In the light-independent reactions of photosynthesis,

• CO2 enters the Calvin cycle and sugars are made.
• H2O is broken down and oxygen is released.
• NADPH is produced and transferred to photosystem I.
• electrons are energized and used to pump H+ ions.

Which of the following statements best describes cellular respiration?

• Sunlight and carbon dioxide are used to make ATP.
• ATP and oxygen are used to make sugars and starches.
• Carbon-based molecules from food and oxygen are used to make ATP.
• ATP and carbon dioxide are used to make ADP and water.

Which of the following are end products of glycolysis?

• two three-carbon molecules, ATP, and NAD+
• carbon dioxide, water, and ATP
• NAD+, oxygen, and two ATP molecules
• pyruvate, 2 ATP
