KHP 420G Exam 1 Questions and Answers Already Passed Rated A+
ATP-PC pathway rate limiting enzyme - Answers creatine kinase
ATP-PC pathway stimulators - Answers ADP
ATP-PC pathway inhibitors - Answers ATP
Glycolosis rate limiting enzyme - Answers phosphofructokinase
Glycolosis stimulators - Answers AMP, ADP, Pi, high ph
Glycolosis inhibitors - Answers ATP, CP, citrate, low ph
Krebs Cycle rate limiting enzyme - Answers isocitrate dehydrogenase
Krebs Cycle stimulators - Answers ADP, Ca, NAD
Krebs Cycle inhibitors - Answers ATP, NADH
Electron Transport rate limiting enzyme - Answers Cytochromoxidase
Electron Transport stimulators - Answers ADP, Pi
Electron Tansport inhibitors - Answers ATP
Resting 02 consumption - Answers 3.5ml/kg/min = 1 MET
Why is fat an excellent storage fuel? - Answers it's energy dense (9.13kcal/g), triglyceride is stored dry so
the energy isn't diluted, fat stores are larger than glycogen stores (can last for weeks)
Beta Oxidation - Answers the process of converting fatty acids to Acetyl-COA
1 FADH = ?ATP - Answers 1.5 ATP
1 NADH = ?ATP - Answers 2.5 ATP
Homeostasis - Answers maintained within a range, maintenance of a constant internal environment
Steady state - Answers balance between demands placed on body and the physiological response to
those demands
Receptor - Answers capable of detecting changes
Integrating Center - Answers assesses input and initiates response
Effector - Answers corrects changes to internal environment
Negative Feedback - Answers response reverses the initial disturbance in homeostasis
, Gain of a system - Answers degree to which the control system maintains homeostasis
Gain = - Answers amount of correction need / amount of abnormality after correction
1st law of Thermodynamics - Answers energy can neither be created nor destroyed
Energy - Answers the capacity to do work
Anabolic reactions - Answers synthesis of molecules
Catabolic reactions - Answers breakdown of molecules
Bioenergetics - Answers converting foodstuffs (fats, proteins, carbohydrates) into energy
Mitochondria - Answers "powerhouse" of the cell, produces lots of energy (majority)
Endergonic reactions - Answers require energy to be added
Exergonic reactions - Answers release energy
Coupled reactions - Answers liberation of energy in an exergonic reaction drives an endergonic reaction
Oxidation - Answers removing an electron
Reduction - Answers addition of an electron
NAD - Answers oxidizing agent, hydrogen carrier, accepts H and drops them off
FAD - Answers reducing agent, hydrogen carrier, accepts H and drops them off
Oxidation and Reduction are... - Answers always coupled reactions
Enzymes - Answers catalysts that regulate the speed of reactions, lower the energy of activation that
drive metabolic pathway
Factors that regulate enzyme activity - Answers low ph (acidic environment) , high temperature
Which fuel source contributes least to fuel exercise? - Answers Protein
Carbohydrates - Answers 1g = 4kcal/energy
Fats - Answers 1g = 9kcal/energy
Protein - Answers 1g = 4kcal/energy
Anaerobic Pathways - Answers do not involve O2, PC breakdown and glycolysis
Aerobic Pathways - Answers require O2, Oxidative phosphorylation
