Question 36 – Energy for biological processes - Questions

Which of the statements about the light-dependent and light-independent stages of photosynthesis is/are correct?

During the light-dependent stage, the photolysis of water occurs on the stroma-facing side of the thylakoid membrane to directly increase the proton concentration in the stroma.
At high light intensities, raising the temperature from $∘C15\ ^\circ\text{C}$ to $∘C30\ ^\circ\text{C}$ has a greater stimulatory effect on the rate of triose phosphate (TP) synthesis than on the rate of photophosphorylation.
If a herbicide blocks electron transport from photosystem II, the concentration of ribulose bisphosphate (RuBP) in the stroma will eventually decrease.

Only 1 and 2 are correct
