Question

Tell two things that happen to put H+ ions in the thylakoid space during the light dependent reactions

Answer 1

Answer:

Electron transfer and presence of thylakoid membrane proteins

Explanation:

The high energy electrons from chlorophyll pass through a chain of proteins called electron transport chain in the thylakoid membrane. These high energy electrons helps H+ ions to come from outside to inside membrane of thylakoid against the concentration gradient which is also contributing factor to build the concentration of H+ inside thylakoid membrane which is used to transfer phosphate to ADP during light depend reactions.
