What is true about the Citric Acid Cycle? - Answer - It's purpose is to produced high energy electrons carriers - It occurs in the mitochondrial matrix for Eukaryotes - Also called the Krebs Cycle If the Krebs Cycle is overstimulated, the body will produce too much what kind of molecules. - Answer Carbon Dioxide (CO2) What is the location of Glycolysis? - Answer The Cytosol Which process in aerobic respiration would not be possible without Oxygen present? - Answer The electron Transport chain What is the purpose of the formation of lactic acid during anaerobic respiration? - Answer It allows NAD+ to reform Reactions that give off energy as they proceed are referred to as what? - Answer Exergonic or Exothermic During Glycolysis, energy is produced as the form of what? - Answer NADH and ATP what is the normal destination of NADH and FADH2? - Answer The electron transport chain proteins During cellular respiration, high energy intermediates are created that can then be oxidized to make ATP. During what stage are these intermediates produced? - Answer Citric Acid Cycle and Glycolysis An unknown molecule is added to an enzyme-catalyzed reaction, immediately decreasing its rate. If the addition of more substrate has no effect, but the addition of an antibody for the unknown molecule restores the initial reaction rate, what form of inhibition is most likely occurring? - Answer Noncompetitive Inhibition Within the Krebs cycle, L-malate and NAD+ come together to form oxaloacetate, NADH, and H+. What type of chemical reaction is responsible for this step in the cycle? - Answer Redox
