Understanding Photosynthesis: From Basics to the Calvin Cycle

What are the essential components required by plants to perform photosynthesis?

• Nitrogen, Oxygen, and Sunlight

• Water, Carbon Dioxide, and Sunlight

• Water, Oxygen, and Carbon

• Hydrogen, Chlorophyll, and Carbon Dioxide

What is the primary function of chlorophyll in photosynthesis?

• To release oxygen

• To absorb photons

• To produce glucose

• To absorb water

Which complex initiates the light-dependent reactions in photosynthesis?

• Photosystem II

• ATP Synthase

• Cytochrome Complex

• Photosystem I

What is the main purpose of the electron transport chain in photosynthesis?

• To create a concentration gradient

• To transport electrons and produce ATP

• To split water molecules

• To convert NADP+ to NADPH

What role does ATP Synthase play in the chloroplast?

• Fixes carbon dioxide into sugars

• Splits water molecules

• Transports electrons

• Generates ATP from ADP

During the Calvin Cycle, what molecule acts as the initial and final acceptor of carbon dioxide?

• NADPH

• Glyceraldehyde 3-Phosphate

• 3-Phosphoglycerate

• Ribulose Bisphosphate

What is the primary function of NADPH in the Calvin Cycle?

• To transport glucose

• To act as an electron donor

• To absorb light

• To provide energy

Which enzyme is responsible for fixing carbon dioxide in the Calvin Cycle?

• Photosystem I

• RuBisCo

• ATP Synthase
