Which shows the effectiveness of wavelengths of light driving photosynthesis?
Correct answer: B. Action spectrum
- A. Absorption spectrum
- B. Action spectrum
- C. Broad spectrum
- D. Narrow spectrum
Explanation
The graph showing relative effectiveness of different wavelengths of light in driving photosynthesis is called action spectrum. It was reported by T. W Engelmann.The action spectrum is a graph that is used to determine the effectiveness of different wavelength of light in driving a specific biological or chemical processes such as photosynthesis. It helps identify the wavelength of light that have the greatest impact on the activity or response being studied.

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.
