Quiz 7 Key All labs 1 Define Coenzyme A coenzyme is a nonprotein organic group capable ofinteracting with an apoenzyme to form a holoenzyme Examples of coenzymes include NAD FAD NADP coenzymeA and coenzymeQ ubiquinone One function of coenzymes is the binding and releasing of electrons and hydrogen protons thus they can be alternately reduced and oxidized during chemical reactions In their reduced form coenzymes store considerable energy Glycolysis Glycolysis means literally the breakdown of sweets and is a metabolic pathway allowing for the catabolism of glucose molecules Each glucose molecule catabolized yields two molecules of pyruvic acid and the energy released is used to form two molecules ofATP net via substrate level phosphorylation Two molecules of NAD are reduced during the process Photophosphorylation Photophosphorylation reactions allow for the production ofATP using light as the energy source Only phototrophs can make ATP in this manner 2 Decreasing the increments ofactivation energy required to initiate chemical reactions 3 Apoenzyme cofactor 4 Cytochromes reduced 5 Temperature light Note Inhibitors only decrease enzyme activity and enhancers only increase it 6 Kinase constitutive 7 Pyruvic acid 8 Cellular respiration Carbon dioxide is produced from the carboxyl groups removed from organic acids just prior to and during the Krebs cycle Each carboxyl group can pass electrons and a hydrogen proton to NAD forming NADH W and what remains of the carboxyl group is carbon dioxide a waste gas Please note This process has nothing to do with glucose or molecular oxygen 9 Acetyl CoA 10 Krebs cycle CalvinBenson cycle 11 Bacteriochlorophylls bacteriorhodopsin 12 Proton motive ATP synthase 13 Plastoquinone ferredoxin 14 Ribulosebisphosphate Carboxylase Oxygenase RuBisCO
