Question

hb unit 2.1 cell energy and photosynthesis quiz 2025 (connected module8)
why does the inside of the thylakoid membrane become positively charged during the light - dependent reactions?
h+ ions are released as water splits and h+ are pumped into the thylakoid space through active transport as the electrons progress through the electron transport chain
h+ ions are released into the stroma as water splits, and electrons are actively transported into the thylakoid space, increasing the positive charge.
atp synthase produces atp from adp.
carbon dioxide builds up in the stroma.

Explanation:

During the light - dependent reactions of photosynthesis, water is split. This releases H+ ions. Also, as electrons move through the electron transport chain, H+ ions are pumped into the thylakoid space by active transport. This accumulation of H+ ions makes the inside of the thylakoid membrane positively charged.

Answer:

H+ ions are released as water splits and H+ are pumped into the thylakoid space through active transport as the electrons progress through the electron transport chain.
