Correct answer: C. 380-750 nm
- A. 300-650 nm
- B. 350-700 nm

- D. 430-790 nm
Explanation
The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. Cone-shaped cells in our eyes act as receivers tuned to the wavelengths in this narrow band of the spectrum. Other portions of the spectrum have wavelengths too large or too small and energetic for the biological limitations of our perception.Wavelength of visible light ranges from 380-750 nm.Visible light consists of seven colours - violet, indigo, blue, green, yellow, orange, and red. Each colour of the visible light spectrum has its distinct wavelength. The wavelengths are as follows:Violet: 380-450 nm Indigo: 450-485 nmBlue: 485-500 nmGreen: 500-565 nmYellow: 565-590 nmOrange: 590-625 nmRed: 625-750 nmDiagram:

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.
