Photosynthesis Processes and Functions

The video covers the top ten questions on photosynthesis, explaining where it occurs in plant cells, the stages involved, and the roles of key molecules like ATP and NADP. It details the light-dependent stage, photolysis of water, and the factors necessary for photosynthesis. The video also discusses the products of the light stage and the enzyme control in the dark stage, emphasizing the importance of light stage products for the dark stage reactions.

Where does photosynthesis occur within the plant cell?

• Mitochondria

• Chloroplast

• Ribosome

• Nucleus

What is the primary purpose of the light-dependent stage in photosynthesis?

• To produce glucose

• To absorb carbon dioxide

• To release oxygen

• To trap sunlight energy

Which of the following is NOT a product of photolysis of water?

• Oxygen

• Glucose

• Protons

• Electrons

Which of these is NOT a factor necessary for photosynthesis?

• Light

• Water

• Nitrogen

• Chlorophyll

What is the role of NADP in photosynthesis?

• It carries electrons and protons

• It absorbs sunlight

• It releases oxygen

• It stores energy

How does ATP contribute to the photosynthesis process?

• It absorbs sunlight

• It provides energy for the dark stage

• It releases oxygen

• It combines with carbon dioxide

What happens to ATP when it releases energy?

• It becomes ADP

• It becomes oxygen

• It becomes glucose

• It becomes NADP

Are the reactions of the light stage enzyme-controlled?

• Yes, they are enzyme-controlled

• No, they occur too quickly

• Yes, but only partially

• No, they are controlled by temperature

Is light required for the dark stage reactions in photosynthesis?

• No, but products of the light stage are needed

• Yes, light is essential

• No, light is not involved at all

• Yes, but only indirect light

What combines with carbon dioxide to form glucose in the dark stage?

• Oxygen and water

• Electrons and protons

• ATP and NADP

• Chlorophyll and light
