Visible light used in photosynthesis ranges from nm?
Correct answer: C. 380-750
- A. 300-700
- B. 350-750
- C. 380-750
- D. 390-790
Explanation
Visible light, which ranges from approximately 380 to 750 nanometers (nm) in wavelength, is indeed crucial to life on Earth. This range of wavelengths includes the different colors of light, from violet at the shorter end to red at the longer end. Visible light is essential for photosynthesis in plants, algae, and some bacteria, as it provides the energy needed to convert carbon dioxide and water into glucose and oxygen.

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.
