Exploring the Process of Photosynthesis

The video explains how plants perform photosynthesis to produce food and oxygen. It covers the role of carbon dioxide and chloroplasts, detailing the light reactions and the Calvin Cycle. The light reactions convert light energy into chemical energy, producing ATP and NADPH. The Calvin Cycle uses these products to synthesize sugar. The video concludes with the production of glucose and oxygen, highlighting their importance for plant metabolism and human consumption.

What is the primary function of photosynthesis in plants?

• To release carbon dioxide into the atmosphere

• To convert carbon dioxide and water into sugar and oxygen

• To produce water and minerals

• To absorb nutrients from the soil

What are thylakoids primarily responsible for in the chloroplast?

• Storing chlorophyll

• Producing carbon dioxide

• Absorbing water from the soil

• Converting light energy to chemical energy

Which molecule acts as an electron carrier in photosynthesis?

• Glucose

• Rubisco

• NADPH

• ATP

What role does ATP synthase play in photosynthesis?

• It produces ATP using a hydrogen ion gradient

• It helps in the electron transport chain

• It captures light energy

• It synthesizes glucose from carbon dioxide

What is the byproduct of water molecules splitting in photosynthesis?

• Carbon dioxide

• ATP

• Glucose

• Oxygen

What is the role of NADPH in the light reactions of photosynthesis?

• It acts as a primary light absorber

• It is used to create a gradient for ATP synthase

• It carries electrons to the Calvin cycle

• It splits water molecules

What is the main product of the Calvin cycle?

• Water

• ATP

• Oxygen

• G3P sugar

Where does the Calvin cycle take place within the chloroplast?

• In the thylakoid membranes

• In the chlorophyll

• In the stroma

• On the outer membrane

Which of the following is not a direct product of the Calvin cycle?

How do plants utilize the sugars produced during photosynthesis?

• To create water molecules

• To absorb more light energy

• To produce more chlorophyll

• To generate ATP through cellular respiration
