Photosynthesis and Cellular Respiration Quiz

What is the primary function of chloroplasts in photosynthesis?

• Store and release oxygen

• Produce and store water

• Regulate the flow of nutrients

• Capture light energy and convert it into chemical energy

Answer explanation

Chloroplasts capture light energy and convert it into chemical energy, which is the primary function in photosynthesis.

Which of the following is a product of the Calvin cycle?

• glucose

• carbon dioxide

• water

• oxygen

Answer explanation

Glucose is a product of the Calvin cycle, where carbon dioxide is converted into glucose through a series of reactions.

Where does the Krebs cycle take place in the cell?

• Endoplasmic reticulum

• Nucleus

• Cell membrane

• Mitochondria

Answer explanation

The Krebs cycle takes place in the mitochondria. It is a key process in cellular respiration, where energy is generated from the breakdown of glucose.

What is the main function of mitochondria in cellular respiration?

• Store water

• Regulate body temperature

• Produce ATP

• Produce glucose

Answer explanation

The main function of mitochondria in cellular respiration is to produce ATP, which is the correct choice.

Which part of the chloroplast is responsible for the light-dependent reactions of photosynthesis?

• Thylakoid membrane

• Stroma

• Cell wall

• Nucleus

Answer explanation

The thylakoid membrane is responsible for the light-dependent reactions of photosynthesis. It contains the necessary pigments and proteins for capturing and converting light energy into chemical energy.

Which molecule is the primary source of energy for the electron transport chain?

• Water

• Glucose

• Carbon dioxide

• ATP

Answer explanation

ATP is the primary source of energy for the electron transport chain. It is a high-energy molecule that powers cellular processes.

What is the function of the inner membrane of the mitochondria?

• Cell division

• Protein synthesis

• Photosynthesis

• ATP synthesis and electron transport chain

Answer explanation

The inner membrane of the mitochondria is responsible for ATP synthesis and the electron transport chain, which generate energy for the cell.

What is the overall equation for photosynthesis?

• 6CO2 + 6H2O → C6H12O6 + 6O2

• 6CO2 + 6H2O + ATP → C6H12O6 + 6O2

• 2CO2 + 2H2O + light energy → C6H12O6 + 2O2

• 6CO2 + 6H2O → C6H12O6 + 6O2

Answer explanation

The overall equation for photosynthesis is 6CO2 + 6H2O → C6H12O6 + 6O2. This equation represents the conversion of carbon dioxide and water into glucose and oxygen through the process of photosynthesis.

Which molecule is produced directly from the Krebs cycle?

• Glucose

• Water

• ATP

• Carbon dioxide

Answer explanation

ATP is directly produced from the Krebs cycle. It is a high-energy molecule used for cellular processes.

What is the overall equation for cellular respiration?

• Glucose + Oxygen -> Carbon Dioxide + Water + ATP

• Oxygen + Water -> Glucose + Carbon Dioxide + ATP

• ATP + Carbon Dioxide -> Glucose + Oxygen + Water

• Glucose + Carbon Dioxide -> Oxygen + Water + ATP

Answer explanation

The overall equation for cellular respiration is Glucose + Oxygen -> Carbon Dioxide + Water + ATP. This equation represents the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP, which is the energy currency of the cell.
