Photosynthesis Light Dependent Reactions

Protons move into the thylakoid due to the

• concentration gradient in the stroma
•   Brownian motion of the protons.
•   peer pressure of the cool electrons in the stroma.  
• movement of electrons through the electron transport chain

ATP gets formed in the light dependent reaction by which process?

• Chemiosmosis
• Photosmosis
• Diffusion
• Active Transport

Which of the following is NOT a product of the light reactions?

• ATP
• NADPH
• Oxygen
• Glucose

What does ATP synthase do?

• Create ATP through chemiosmosis.
• Break down ATP through chemiosmosis.
• Break down NADPH. 
• Create NADPH.

What is the purpose of splitting water in PS2 of the light dependent reaction?

• Provides e- for PS2 and H+ for the thylakoid space
• To produce Oxygen for animals
• There is no purpose
