Q-2. What substance is/are needed in light-dependent stage of photosynthesis?

• oxidised NADP

• ATP

• light

Q-3. Where is the specific location in a chloroplast that a light-dependent stage take place?

• Granum

• Thylakoid

• Stroma

• inner membrane of a chloroplast

Q-4. What will light do in photosynthesis?

• Splitting water molecules

• Giving up electrons

• creating ATP

• activating chlorophylls

Q-5. During photosynthesis, ATP is formed in ...

• Photosystem II

• cyclic photophosphorylation

• Photosystem I

• photolysis of water

Q-6. The beginning process in non-cyclic photophosphorylation is/are ...

• photolysis of water

• photosystem I

Q-7. Final products of light-dependent stage of photosynthesis is/are ...

• ATP

• reduced NADP

• glucose

Q-8. Which is the correct statement about the light-independent stage of photosynthesis?

• A. Photosynthesis involves two photosystems where pigments absorb energy from light

• B. Water will provides energy in the form of electron that moves from photosystem I to photosystem II

• C. reduced NADP is formed as a final product of cyclic photophosphorylation

• D. Electron carrier in photosystem I will decrease the energy of ATP gradually before the ATP is sent to light-independent stageD.
