KHP 420G EXAM 1 2025 QUESTIONS
AND ANSWERS
ATP-PC pathway rate limiting enzyme - ANS creatine kinase
ATP-PC pathway stimulators - ANS ADP
ATP-PC pathway inhibitors - ANS ATP
Glycolosis rate limiting enzyme - ANS phosphofructokinase
Glycolosis stimulators - ANS AMP, ADP, Pi, high ph
Glycolosis inhibitors - ANS ATP, CP, citrate, low ph
Krebs Cycle rate limiting enzyme - ANS isocitrate dehydrogenase
Krebs Cycle stimulators - ANS ADP, Ca, NAD

, Electron Tansport inhibitors - ANS ATP
Resting 02 consumption - ANS 3.5ml/kg/min = 1 MET
Why is fat an excellent storage fuel? - ANS 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 - ANS the process of converting fatty acids to Acetyl-COA
1 FADH = ?ATP - ANS 1.5 ATP
1 NADH = ?ATP - ANS 2.5 ATP
Homeostasis - ANS maintained within a range, maintenance of a constant internal
environment
Steady state - ANS balance between demands placed on body and the physiological response
to those demands
Receptor - ANS capable of detecting changes
Integrating Center - ANS assesses input and initiates response
Effector - ANS corrects changes to internal environment
Negative Feedback - ANS response reverses the initial disturbance in homeostasis
