Which of the following events supports ATP synthesis through chemiosmosis?

Question

Which of the following events supports ATP synthesis through chemiosmosis? (A) Lumen of thylakoid has low electrochemical potential gradient as compared to stroma of chloroplast (B) Lumen of thylakoid has high H+ level as compared to stroma of chloroplast (C) Energy is required to pump protons across a thylakoid membrane (D) ATP arrow ADP + Pi, requires ATP synthase

Tardigrade Admin · Accepted Answer

In lumen of thylakoid there is higher H+ concentration than stroma.

Q. Which of the following events supports ATP synthesis through chemiosmosis?

Lumen of thylakoid has low electrochemical potential gradient as compared to stroma of chloroplast

Lumen of thylakoid has high $H^{+}$ level as compared to stroma of chloroplast

Energy is required to pump protons across a thylakoid membrane

$A TP \to A D P + P i$ , requires ATP synthase

In lumen of thylakoid there is higher $H^{+}$ concentration than stroma.
