5 Multiple choice questions

  1. most important energy
    -productof both aerobic and anaerobic energy
    -3 phosphate molecules
    -produced from ADP +Pi+H
  2. 8-12 minutes
  3. -all systems work at same time to produce ATP, some take more time to generate ATP
    -more intense activity, short duration- anaerobic energy sources
    -less intense/ long duration makes use of aerobic energy sources
    -no one sourse wrkjs at one time, gradual transition from one to another
  4. stored in muscles, is added to ADP when ATP is broken down, is used to regain energy.
    -Has a life of about 20-30 sec. but is regenerated in about 3 minutes.
  5. -buffering hydrogen ions increases performance and recovery in activities that increase IM acidity
    -endurance & sprint training increase buffering capabilities

4 True/False questions

  1. Second Pathway-krebs cycle (citris acid cycle)
    -primary purpose is to remove hydrogen ions (oxidation) from carbs, fats and proteins
    - O2 is used to produce hydrogen ions


  2. endergonicneeds energy


  3. ATP-PC system-characteristics
    -energy source for activities requiring much energy per second
    -examples: sprinting, lifting a heavy weight
    -can only provide energy for a
    short time


  4. GlycolysisYields energy
