A graph plotting the absorption of light of different wavelengths by a pigment is called:
Correct answer: A. Absorption spectrum
- A. Absorption spectrum
- B. Spectrophotometer
- C. Carotenoids
- D. Xanthophylls
Explanation
The correct answer is absorption spectrum because it is a graph that shows how much light of different wavelengths is absorbed by a pigment. This graph is crucial in understanding which wavelengths of light are most effectively used by a pigment in processes like photosynthesis.The spectrophotometer is incorrect because it refers to an instrument, not a graph. Carotenoids and xanthophylls are specific types of pigments, not graphs or plots, and are therefore incorrect in this context.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
