Vedclass · Answer

(C) The Emerson effect is defined as the increase in the rate of photosynthesis when light of two different wavelengths (short and long) is provided simultaneously,compared to the sum of the rates when each wavelength is provided separately.Mathematically,the Emerson effect $(E)$ is calculated as the ratio of the rate of oxygen production in a mixed beam of light $(x)$ to the sum of the rates of oxygen production in low wavelength light $(y)$ and high wavelength red light $(z)$.Therefore,the formula is $E = \frac{x}{y + z}$.

If $E$ is the Emerson effect,$x$ is the rate of oxygen production in a mixed beam of light,$y$ is the rate of $O_2$ production in low wavelength light (short wavelength),and $z$ is the rate of $O_2$ evolution in high wavelength red light,what will be the value of $E$?
