1. A particular plant has chlorophyll a & b, but no other photo pigments. How will this affect the wavelengths of lights under which it can be successfully grown? Chlorophyll a and b have different wavelength absorptions, chlorophyll a absorbs best at about 420nm, chlorophyll b at about 460nm. But chlorophyll does not absorb very well the green light, so the plant has less possibilities of absorbing energy essential for photosynthesis. 2. RUBISCO is allosterically activated by NADPH. What will happen in the dark reactions if no NADPH is available If extra NADPH is available? If no NADPH is available, there is no reason for carbon fixation to occur and if it is available calvin cycle will continue. If extra NADPH is available, then calvin cycle continues. 3. What is meant by inductive resonance? How does it work? Inductive resonance is a process that when a photon hits one of the pigments, it gets transferred from one chlorophyll to another by creating an electromagnetic field that passes the energy all the way to the reaction center.
