Document Summary

Exam i will cover material from lectures 15-22 (feb. 6 feb. 27) including two wednesday activities (photosynthesis; respiration): carbohydrates. Polysaccharides chains of sugar molecules i. e. starch bonds: how do 1-4 or 1-6 glycosidic bonds differ in their influence on the shape of polysaccharides, polysaccharides can have digestible alpha glycosidic bonds (starch in. Alpha: all the hydroxyl groups are in the same orientation. Beta: the hydroxyl groups flip orientation on every other monomer. Starch is helical (alpha is helical) really dense. If it"s not helical, then it"s a straight molecules with alternating. Co2 is reduced to form sugar, h2o is oxidized to form o2: photosynthesis is part of an anabolic-catabolic cycle that transforms light energy into chemical energy. sugars. Grana: stacks of thylakoids; more efficient light capturing dark reactions: explain how the relationship between the light reactions and the dark reactions is an example of reaction coupling. The products of the light reactions drive the dark reactions to occur.
