What is the main function of H+ ions produced during the light dependent reaction?

• They are released as a waste product

• They make energy storing molecules like ATP and NADPH

• They are used to split glucose

• They are stored in the nucleus

What happens to the O₂ produced during the light dependent reaction?

• It is used to make glucose

• It enters the atmosphere as a waste product

• It is stored in the thylakoid

• It is converted into ATP

Why is sunlight important in the light dependent reaction of photosynthesis?

• It provides energy to split water molecules

• It cools down the plant

• It helps in the absorption of minerals

• It is used to make proteins

Explain how the splitting of water during the light dependent reaction contributes to the formation of ATP and NADPH.

• The splitting of water releases O₂ and H⁺ ions; the H⁺ ions are used to generate ATP and NADPH, which store energy for the plant.

• The splitting of water produces glucose directly.

• The splitting of water only releases oxygen for the plant to use.

• The splitting of water cools the plant.

Which two energy-carrying molecules are produced during the light-dependent reactions?

• ATP and NADPH

• ADP and NADP+

• Glucose and Oxygen

• Water and Carbon dioxide

Explain why the light-dependent reactions are important for the process of photosynthesis.

• They produce energy-rich molecules (ATP and NADPH) needed for the next stage of photosynthesis.

• They directly produce glucose for the plant.

• They absorb carbon dioxide from the air.

• They store energy in the form of fats.
