Photosynthesis and Respiration Quiz

What is the primary function of photosynthesis in plants?

• To produce oxygen

• To convert light energy into chemical energy

• To absorb carbon dioxide

• To release water

DOK Level 1: Recall

Which molecule is produced as a result of glycolysis?

• ATP

• Glucose

• Pyruvate

• NADPH

Tags

DOK Level 1: Recall

Explain how the light reaction and dark reaction are interconnected in photosynthesis.

• The light reaction produces ATP and NADPH, which are used in the dark reaction to synthesize glucose.

• The dark reaction produces ATP and NADPH, which are used in the light reaction to synthesize glucose.

• The light reaction and dark reaction occur simultaneously and independently.

• The dark reaction occurs only at night, while the light reaction occurs during the day.

During cellular respiration, what is the role of the electron transport chain?

• To break down glucose into pyruvate

• To produce ATP through oxidative phosphorylation

• To convert pyruvate into acetyl-CoA

• To fix carbon dioxide into organic molecules

DOK Level 1: Recall

Describe the role of ATP in cellular respiration.

• ATP is a waste product of cellular respiration.

• ATP provides energy for cellular processes by releasing a phosphate group.

• ATP is used to store oxygen in cells.

• ATP is converted into glucose during cellular respiration.

How does the Krebs cycle contribute to the production of ATP in cellular respiration?

• It directly produces large amounts of ATP.

• It generates electron carriers that are used in the electron transport chain to produce ATP.

• It converts glucose into pyruvate, which is then used to produce ATP.

• It stores energy in the form of glucose.

DOK Level 2: Skill/Concept

What is the main purpose of NADPH in photosynthesis?

• To transport oxygen

• To provide energy for the Calvin cycle

• To absorb light energy

• To release carbon dioxide

Tags

DOK Level 1: Recall

Compare the processes of photosynthesis and cellular respiration in terms of energy flow.

• Both processes store energy in the form of glucose.

• Photosynthesis stores energy in glucose, while cellular respiration releases energy from glucose.

• Both processes release energy from glucose.

• Photosynthesis releases energy, while cellular respiration stores energy.

DOK Level 2: Skill/Concept

Which of the following best describes the role of glucose in cellular respiration?

• Glucose is a waste product of cellular respiration.

• Glucose is broken down to release energy stored in its chemical bonds.

• Glucose is used to transport oxygen in the cell.

• Glucose is converted into ATP directly.

DOK Level 1: Recall

Analyze the impact of light intensity on the rate of photosynthesis.

• Increasing light intensity decreases the rate of photosynthesis.

• Increasing light intensity increases the rate of photosynthesis up to a certain point, after which it plateaus.

• Light intensity has no effect on the rate of photosynthesis.

• Decreasing light intensity increases the rate of photosynthesis.
