Q. Cyclic phosphorylation occurs at which wavelength
A) Wavelength beyond 800 nm
B) Wavelength beyond 680 nm
C) Wavelength below 680 nm
D) Wavelength below 500 nm
Explanation
Cyclic phosphorylation occurs only when wavelength beyond 680 nm is available for excitation. Non-cyclic phosphorylation occurs in the membrane or lamellae of grana. Because membrane or lamellae of grana have both photosystem (PS-I and PS-II) and in non-cyclic phosphorylation both PS-I and PS-II participates
