16
Q

What is the Cori Cycle?

A
  • How body breaks down latic acid
  • Glycolysis moves acid to blood
  • Liver recylces acid
17
Q

Aerobic Oxidative System

A
  • O2 required
  • By-products are CO2 and H2O
  • Primary source of less intense excercise
18
Q

Aerobic Oxidative System (2 Pathways) (3 Steps)

A
  1. Key molecule formation (Acetyl CoA)
  2. Kreb’s Cycle Pathway
  3. Electron transport chain pathway
19
Q

Acetyl CoA

A
  • Main energy for Kreb’s Cycle
  • Carbs, Proteins, and Fats
20
Q

What system can use all 3 Macronutrients? (Carbs, Lipids, Protein)

A

Oxidative System

21
Q

Latic Acid being recycled in the liver is called

A

Cori Cycle

22
Q

What is the best way to measure ATP-PC

A

Maximum force production, and under a short period of time.

23
Q

How to measure glycolysis

A

Lactate Threshold

24
Q

What does latic acid store?

A

Pyruvate and H atoms

25
Q

What is Beta Oxidation?

A
  • Fatty Acid –> ATP
  • Mitochondria
