Exam Questions With Verified Answers
Bioenergetics
The study of how energy flows in the human body
Energy
The ability to do physical work
Metabolism
Sum of all chemical reactions in the body that either use or create energy
Catabolic process
- Large molecules are broken down into smaller ones
- Digestion of food
Anabolic process
- Cells build larger molecules from smaller ones
- Use of amino acids to build muscles
Adenosine Triphosphate
ATP
Adenosine~P~P~P
Molecular structure of ATP
ATP
Chemical compound made up of adenosine and three phosphate molecules
ATP
Energy currency of the body
Systems that produce ATP
- ATP-CP (creatine phosphate) system (anaerobic system)
- Lactic acid or glycolytic energy system (anaerobic system)
- Aerobic or oxidative energy system
Creatine Phosphate
CP
Anaerobic system
What system uses the ATP-CP system?
Anaerobic system
What system uses the Lactic acid or Glycolytic energy systems?
, Anaerobic system
- Operates without the use of oxygen
- Limited and inefficient
- Provides most of the energy at the start of the exercise
Aerobic system
- Operates using oxygen
- Very efficient because it uses an abundant supply of fat and carbohydrates to create ATP to fuel
activity
Rating of Perceived Exertion
RPE
Heart Rate Reserve
HRR
RPE
Used to measure the intensity of your exercise
RPE
AKA The Borg Scale
RPE
Range from 6 - 20
Follows the general heart rate of a healthy adult by multiplying by 10
HRR
The difference between a person's measured or predicted maximum heart rate and resting heart rate
Anaerobic metabolism
- ATP created through a chemical reaction that does not require oxygen
- Activity so intense that the body cannot get oxygen to the muscles fast enough, so ATP is created
without it
ATP-CP Phosphagen System
Provides fuel for up to 10 seconds at maximal activity
Phase 1 of ATP-CP Phosphagen System
- Stored ATP
- Fuel for 1-2 seconds at maximal effort
ADP + P + Energy
ATP-CP Phase 1
- ATP splits into: ___ + ____ + _____
