Spectrophotometer is used to measure:
Correct answer: D. Absorption of different wavelengths
- A. Absorption of CO2
- B. Absorption of O2
- C. Reflection of pigments
- D. Absorption of different wavelengths
Explanation
Spectrophotometer is a device that is designed to measure the absorption of different wavelength of light by substance across a range of wavelengths. By analysing the absorption pattern scientist can gain insight into the chemical composition, concentration or other properties of the sample.

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.
