Question

During a lab experiment, thylakoid gets punctured accidentally. Due to this, the interior of the thylakoid is no longer separated from stroma. Which of the following processes is affected by it?
(correct answer + 1, wrong answer - 0.25)

• A. ATP formation
• B. Absorption of light
• C. Electron flow from PS-I to PS-II
• D. All of the above

Answer 1

The correct option is A ATP formation

Due to the punctured thylakoid membrane, the interior of thylakoid is no longer separated from stroma that leads to the disturbed proton gradient.

The proton concentration between the thylakoid membrane and stroma becomes the same, i.e., there is no proton gradient. The ATP synthase will not function in the absence of a proton gradient.

Hence, no ATP formation takes place.
