The Action Spectrum of Photosynthesis Best Matches the Absorption Spectrum

Question

The action spectrum of photosynthesis best matches the absorption spectrum of
A) ATP.
B) NADPH.
C) carotenoids.
D) carbohydrates.
E) chlorophylls a and b .

Accepted Answer

The action spectrum of photosynthesis, which indicates the effectiveness of different wavelengths of light in driving the process, closely matches the absorption spectrum of chlorophylls a and b. These pigments are primarily responsible for absorbing light energy used in photosynthesis.
