SI #13

What is the primary function of the electron transport chain in the light-dependent reactions of photosynthesis?

• Synthesize glucose.

• Produce oxygen.

• Generate ATP and NADPH.

• Fix carbon dioxide.

The electrons excited by sunlight in PSII are passed on to:

• Oxygen.

• NADPH.

• The electron transport chain.

• Chloroplasts.

Which statement best describes the relationship between photosynthesis and cellular respiration in plants?

• Photosynthesis produces glucose and oxygen, both of which are used in cellular respiration.

• Photosynthesis occurs only in animals, while cellular respiration happens in plants.

• Photosynthesis and cellular respiration both produce oxygen as a main product.

• Cellular respiration produces light, which is utilized by photosynthesis.

The main product of photosynthesis that is utilized in cellular respiration is:

• NADPH.

• Water.

• Oxygen.

• Glucose.

Which of the following is NOT an input for the Calvin Cycle?

• ATP.

• NADPH.

• Oxygen.

• CO2.

What is a major output of the Calvin Cycle?

• ATP.

• Glucose.

• Oxygen.

• Water.

Which molecule produced in the light reactions of photosynthesis is essential for the Calvin Cycle?

• Glucose.

• Water.

• NADPH.

• O2.

The ATP and NADPH produced during the light-dependent reactions are used in the Calvin Cycle to:

• Excite electrons.

• Capture light energy.

• Fix carbon dioxide into organic molecules.

• Split water molecules.

What happens to an animal cell when placed in a hypotonic solution?

• It swells.

• It shrinks.

• It remains unchanged in size.

• It undergoes mitosis.

In which type of solution does water move out of the cell, causing the cell to crenate?

• Hypotonic

• Isotonic

• Hypertonic

• Osmotic
