An instrument that is used to measure the relative abilities of different pigments to absorb different wavelengths of light is called
Correct answer: D. Spectrophotometer
- A. Spectrometer
- B. Photometer
- C. Barometer
- D. Spectrophotometer
Explanation
A spectrometer separates and measures the spectral components of a physical phenomenon. A photometer is an instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared, including the visible spectrum. A barometer is an instrument used to measure atmospheric pressureA spectrophotometer performs quantitative measurements of reflectance or transmission properties of a material as a function of wavelength.

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.
