Question

question 26 (1 point)
the light - dependent reaction takes place
outside the chloroplast.
inside the chloroplast.
on the thylakoid membrane.
in the stroma.
inside the granum.
question 27 (1 point)
the light - dependent reactions rely on all of these except
chemiosmosis.
p680.
co₂.
h₂o.
photons.

Explanation:

For Question 26, light - dependent reactions occur on the thylakoid membrane within the chloroplast. Chloroplasts are the organelles for photosynthesis, and the thylakoid membrane contains the necessary pigments and electron - transport chain components. For Question 27, light - dependent reactions use chemiosmosis to produce ATP, P680 is a photosystem II reaction - center chlorophyll, water is split to provide electrons and protons, and photons are the energy source. Carbon dioxide is used in the light - independent reactions (Calvin cycle), not in the light - dependent reactions.

Answer:

Question 26: C. on the thylakoid membrane.
Question 27: C. CO₂.
