HKIN 303 FINAL EXAM CH 3 QUESTIONS WITH CORRECT ANSWERS What is Adenylate kinase? - Answer-Enzyme that adds phosphate to ADP What does fast glycolysis end in? - Answer-ends with pyruvate What does slow glycolysis end in? - Answer-you can go into kerb's cycle & electron transport change What is the primary function of the Cori Cycle? - Answer-- One option where the lactic acid can go - Where we are transporting lactate in the blood to the liver - In the liver the lactic acid is reconverted back to glucose What is hexokinase? - Answer-Enzyme 1 that phosphorylates glucose What is the role of PFK in glycolysis? - Answer-reaction 3, adds phosphate to fructose 6 phosphate What is the effect of pH on glycolysis? - Answer-Low pH increases glycolysis What is the effect of AMP (adenosine myophosphate) on glycolysis? - Answer-High AMP increases glycolysis What is OBLA? - Answer-- Specific value when the concentration is 4 millimoles per liter - The exercise intensity at which lactate production in the muscles exceeds lactate clearance, resulting I the accumulation of lactate in the bloodstream (AKA. Lactate threshold) - Represent the highest exercise intensity that can be sustained for an extended period of time without fatigue What is the Lactate Threshold? - Answer-- Where lactic acid goes from a steady state to a spike in increase - 75% before there is a rapid increase in blood lactate accumulation - this person can work @ 75% of their vo2 max - Trained people will be able to go for longer
