PHOTOSYSTEM e- 1 st step- Light excites electrons on chlorophyll. Which wavelengths of light have the greatest effect on plants? Red Blue True or False All organisms on earth depend upon light for their energy needs. Modified All organisms on earth depend upon light, directly or indirectly , for their energy needs. And the answer is False! The notable exception from the sea! Deep sea thermal vents, smokers and geysers Thermal Vents Chemosynthesis produces sulfur Lots of bacteria The true statement Most organisms on earth depend upon light, directly or indirectly, for their energy needs. sunlight H 2 O CO 2 NADPH alvin ATP Calvin cycle ADP NADP + O 2 sugar Photosynthesis comes in Two Metabolic Pathways Light Reaction Thylakoid membrane In: Sunlight & Water Out: ATP & NADPH...
