Assume the thylakoid membrane within a chloroplast is punctured so that there is no separation between lumen stroma of thylakoid. Which of these process would be most affected?

Question

Assume the thylakoid membrane within a chloroplast is punctured so that there is no separation between lumen stroma of thylakoid. Which of these process would be most affected? (A) the splitting of water (B) the synthesis of ATP (C) reduction of NADP + (D) the flow of electrons from PS - II to PS - I

Tardigrade Admin · Accepted Answer

According to chemiosmotic hypothesis (Mitchell 1961 ) the ATP is synthesized on ATPase complexes located on the non appressed portions of thylakoid membranes particularly towards margins. Therefore, if the thylakoid membrane within a chloroplast is punctured so that there is no separation between lumen and stroma of thylakoid, synthesis of ATP will be affected the most.
