Question

question 28 (1 point)
cyclic photophosphorylation involves
photosystem i.
photosystem ii.
nadp+ is reduced to form nadph.
production of o2.
h2o is broken to provide electrons.
question 29 (1 point)
how does the light dependent reactions contribute to the production of carbohydrates?
o2 is used to power the calvin cycle.
atp and nadph power the calvin cycle.
photon energy is passed to rubp.
co2 is modified to join the calvin cycle.
atp and nadph combine 2 g3p molecules to make glucose.

Explanation:

Cyclic photophosphorylation only involves Photosystem I and generates ATP without the production of NADPH or O₂. The light - dependent reactions produce ATP and NADPH which are used to power the Calvin cycle for carbohydrate production.

Answer:

Question 28: Photosystem I.
Question 29: ATP and NADPH power the Calvin cycle.
