One of the important waste products of photosynthesis is oxygen gas. Where does this oxygen gas come from? Oxygen is released when water is broken down to extract electrons and protons for use in the light reactions. The light reactions produce _____. oxygen, NADPH, and ATP 00:07 01:24 The thylakoid membranes bring together the components necessary to carry out the _____. light reactions Incoming photons of light energy initiate photosynthesis by _____. excitin...

beta-oxidation correct answer: enzymes repeatedly split off pairs of they hydrogenated carbon atoms that make up a fatty acid and join each pair to coenzyme A to form acetyl-CoA Chloroplasts correct answer: light harvesting structures found in photosynthetic eukaryotes; synthesize a few polypeptides compare and contrast archaeal flagella with bacterial flagella correct answer: archaeal are about half as thick as bacteria; not hollow; lack a central channel; flow together; powered by ATP...
