BIOL 1201 : Exam 2 Clicker Questions
Document Summary
Enzymes work by lowering activation energy barrier true. Your roommates side of room keeps getting messier 2nd law. Chemical rxn only proceed spontaneously in downhill rxn true. Delta g represents delta gproducts delta greactants. Complete the equation (delta g=delta h t delta s) Enzymes accelerate rxn by making overall energetics more favorable false. Specialized cellular compartment for digestion of food particles lysosome. The binding of oxygen to hemoglobme is an example of cooperativity true. Chemical transformation occur in small steps; each step is catalyzed by specific enzyme. The oxidation of glucose releases 680 kcal/mol delta g. Glycolysis is activated up to several hundred folds. Production of 2 pyruvates results in production of 2 nadh molecules. Phosphorolation rxns are catalyzed by enzymes called kinases. Nadh and fadh2 are used to produce atp in mitochondria, through oxidative phosphorylation, and oxygen is used at this step to produce h2o. High energy light which may damage biological molecules ultraviolent.
