Photosynthesis and Cellular Respiration Quiz

Photosynthesis: ________ + 6 H2O + Light Energy (LE) → ________ + 6 O2

Photosynthesis: ________ + Water + Light Energy (LE) → ________ + Oxygen

Cellular respiration: ________ + 6 O2 → ________ + 6 CO2 + ________ (Adenosine Triphosphate)

Cellular respiration: ________ + Oxygen → ________ + Carbon Dioxide + ________ (cellular energy)

Both cellular respiration and photosynthesis are examples of:

• A. Reversible reactions

• B. Processes that happen in animals

• C. Biochemical pathways

• D. All of the above

Answer explanation

Both cellular respiration and photosynthesis are biochemical pathways.

The inputs for the light dependent reactions are:

• A. NADPH and ATP

• B. Water and Sunlight

• C. Sunlight and ATP

• D. NADPH and Water

Answer explanation

The inputs for the light dependent reactions are water and sunlight, as they are required for the process of photosynthesis.

The inputs for the light-independent reactions (Calvin Cycle) are:

• A. NADPH and ATP

• B. Water and Sunlight

• C. Sunlight and ATP

• D. NADPH and Water

Answer explanation

The inputs for the Calvin Cycle are NADPH and ATP, which are used in the light-independent reactions.

In photosynthesis ________ energy is converted into ________ energy.

• A. Chemical/Light

• B. Light/Chemical

• C. Light/Light

• D. Chemical/Chemical

Answer explanation

In photosynthesis, light energy is converted into chemical energy. The correct answer is B. Light/Chemical.

The outputs of light independent reactions(Calvin) are:

• A. Glucose and Oxygen

• B. ATP and NADPH

• C. Water and Oxygen

• D. ATP and Water

Answer explanation

The outputs of light independent reactions (Calvin) are ATP and NADPH, as they are used in the synthesis of glucose during photosynthesis.

The outputs of the light dependent reactions are:

• A. ATP, NADPH, and Oxygen

• B. Water, ATP, and Oxygen

• C. Carbon Dioxide, Water, and ATP

• D. Water, Carbon Dioxide, and Oxygen

Answer explanation

The outputs of the light dependent reactions are ATP, NADPH, and Oxygen. These products are essential for the subsequent steps of photosynthesis.
