Q: Assume you have a solution of mixed plant pigments; however, you are only intere

The correct option is 485 nm. The absorption for chlorophyll B is maximum at 485 nm. The spectrophotometer can measure the absorption by chlorophyll B best at 485 nm, because it absorb matximum at 485 nm. The other wavelengths are least affected by chlorophyll A or carotenoids.

Question

Assume you have a solution of mixed plant pigments; however, you are only interested in the concentration of chlorophyll b. To what wavelength would you set the spectrophotometer to determine Chlorophyll B concentration. Please Explain your reasoning!

Assume you have a solution of mixed plant pigments, however, you are only interested in the concentration of chlorophyll b. To what wavelength would you set the spectrophotometer to determine the concentration of chlorophyll b?

Explanation / Answer

The correct option is 485 nm.

The absorption for chlorophyll B is maximum at 485 nm. The spectrophotometer can measure the absorption by chlorophyll B best at 485 nm, because it absorb matximum at 485 nm. The other wavelengths are least affected by chlorophyll A or carotenoids.
