In oxygenic photosynthesis, which pigment molecule in plant chloroplasts primarily absorbs sunlight to drive the light reactions?
A
Cellulose
B
NADPH
C
Chlorophyll a
D
Ribulose-1,5-bisphosphate (RuBP)
Verified step by step guidance1
Understand that oxygenic photosynthesis involves capturing light energy to drive the light reactions, which occur in the chloroplasts of plant cells.
Identify the role of pigment molecules in photosynthesis: pigments absorb specific wavelengths of sunlight to initiate the light-dependent reactions.
Recall that cellulose is a structural carbohydrate in plant cell walls and does not absorb light for photosynthesis.
Recognize that NADPH is an electron carrier produced during the light reactions, not a pigment that absorbs light.
Know that chlorophyll a is the primary pigment molecule in chloroplasts responsible for absorbing sunlight to drive the light reactions, while RuBP is involved in the Calvin cycle, not light absorption.
