Aerobic Exercise 2 Flashcards
What are the 3 stages in aerobic metabolism?
- Glycolysis
- Krebs Cycle
- Electron transport chain
How many ATPs are produced from glycolysis?
2ATP
How many ATPs are produced from the Krebs cycle?
6ATPs
How many ATPs are produced from the electron transport chain?
30ATPs
Where does the Krebs cycle occur?
In the mitochondria
Where does glycolysis occur?
The cytoplasm
Where does the electron transport chain occur?
The inner mitochondria membrane
What is fat stored as and where?
Fat is stored as adipose tissue, peripheral or intramuscular
What is the process that breaks down fat?
Beta oxidation
How is fat transported?
Plasma albumin
What does glycolysis require and produce?
- Glycogen, glucose, ADP, NAD+
* produces pyruvate and ATP
What does beta oxidation require and produce?
- FFAs and ADP
* produces Acetyl CoA, ATP
What does the Krebs cycle require and produce?
- ADP, NAD+, pyruvate and Acetyl CoA
* produces ATP, CO2 and NADH
What does the electron transport chain require and produce?
H2O and ATP
Name a limitation of HR analysis?
Significant lag time between the start of exercise and the HR beginning to reflect the intensity of the work. HR stable after ~45s.
