Understanding the Calvin Cycle

What is the primary role of chloroplasts in the Calvin Cycle?

• To generate oxygen

• To absorb sunlight

• To fix CO2 and produce carbohydrates

• To break down glucose

Which enzyme is responsible for carbon fixation in the Calvin Cycle?

• NADPH oxidase

• ATP synthase

• Rubisco

• Hexokinase

What are the energy molecules used in the Calvin Cycle to transform three-carbon molecules?

• GTP and FADH2

• ATP and NADPH

• ADP and NADH

• AMP and NADP+

During which phase of the Calvin Cycle is RuBP regenerated?

• RuBP regeneration

• G3P harvest

• Energy investment

• Carbon fixation

Why is Rubisco considered the most abundant protein on Earth?

• It is used in cellular respiration

• It is found in all animals

• It plays a crucial role in photosynthesis

• It is a component of DNA
