- Based on the graph below, what can you infer? Absorption and Action Spectra 400 500 600 700 Wavelength of light (nm) photosynthesis is most active between 400- 475. That is why plants are green photosynthesis is most active between 450 -550. That is why plants are green photosynthesis is most active between 600- 700. That is why plants are green both a and c are correct There is not enough evidence in the graph to infer any of the above Absorbance / Photosynthetic RateWhich of the following statements about the light reactions of photosynthesis are correct? 1. Absorption of light does one thing: it makes chlorophyll easier to oxidize. 2. In PSII, the rate of damage to the D1 protein can never exceeds the rate of repair. 3. Electron transport is spontaneous (exergonic) as electrons move from P680* to P700+. 4. Compared to anoxygenic photosynthesis, in oxygenic photosynthesis less light needs to be absorbed to reduce NADP+. A. 1,2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1,2,3 and 4 are correctExplain in detail of the stages of photosynthesis without explaining all the reactions of each pathways, but state the key steps of each pathway.
