Metabolism and Energy Flashcards
Metabolism
Total of all chemical reactions that occur in body
Anabolic
Building up
Catabolic
Tear down
Bioenergetics
Converting foodstuff into usable energy
Thermodynamics (1st Law)
Energy cannot be created or destroyed
Thermodynamics (2nd Law)
Process always go in order of randomness
Entropy
Quantity of heat in system able to do work
Cytosol
Anaerobic production w/o O2
Mitochondria
Aerobic production w/ O2
ATP
Energy made of adenine, ribose, 3 phosphate
Phosphorylation
Energy released can be used by body
Resynthesis
ATP made by recombination of ADP and Pi
ATP-PC System (Creatine)
Anaerobic, Immediate Energy, 7-12 sec.
What is Glycolysis?
Anaerobic, uses blood glucose
What is Anaerobic Threshold?
When latic acid builds up
What is the Cori Cycle?
- How body breaks down latic acid
- Glycolysis moves acid to blood
- Liver recylces acid
Aerobic Oxidative System
- O2 required
- By-products are CO2 and H2O
- Primary source of less intense excercise
Aerobic Oxidative System (2 Pathways) (3 Steps)
- Key molecule formation (Acetyl CoA)
- Kreb’s Cycle Pathway
- Electron transport chain pathway
Acetyl CoA
- Main energy for Kreb’s Cycle
- Carbs, Proteins, and Fats
What system can use all 3 Macronutrients? (Carbs, Lipids, Protein)
Oxidative System
Latic Acid being recycled in the liver is called
Cori Cycle
What is the best way to measure ATP-PC
Maximum force production, and under a short period of time.
How to measure glycolysis
Lactate Threshold
What does latic acid store?
Pyruvate and H atoms
