Question 1

2)

Answer 1

A proton gradient is formed as the photolysis of water results in a high concentration of hydrogen ions in the thylakoid lumen

Question 2

5)

Answer 2

ATP is produced during a process known as photophosphorylation (ADP + Pi → ATP) using the proton gradient between the thylakoid lumen and stroma to drive the enzyme ATP synthase

Question 3

4)

Answer 3

Reduced NADP (NADPH) is produced when hydrogen ions in the stroma and electrons from the electron transport chain combine with the carrier molecule NADP

Question 4

1)

Answer 4

Light energy is used to breakdown water in a reaction known as photolysis; this produces hydrogen ions, electrons, and oxygen in the thylakoid lumen

Question 5

3)

Answer 5

Electrons travel through an electron transport chain of proteins within the membrane
