Question

what happens to the rate of atp synthesis if the ph of the thylakoid lumen decreases?

Answer 1

Answer:INCREASE

Explanation:

The ph in the thylakoid lumen is about 7, and in the stroma about 8.

During the synthesis of the ATP, the direction of the proton is from the thylakoid lumen (positive sire) to stroma (negative side). According to the question, the ph decreases in the thylakoid lumen, and it means that the concentration of protons increases in the thylakoid lumen. Therefore, the rate of the ATP synthesis increases.

Answer 2

If the pH of the thylakoid lumen decreases, then the rate of ATP synthesis increases.

What is photosinhtesis?

Photosynthesis refers to different reactions by which plants can produce carbohydrates by using energy from the sun.

• Photosynthetic reactions produce ATP in the chloroplasts by using a proton gradient.

• More protons present in the lumen of chloroplasts will result in a higher supply of these protons in the stroma.

In conclusion, if the pH of the thylakoid lumen decreases, then the rate of ATP synthesis increases.
