Metabolism Flashcards
At the cost of 2 ATP, glucose is broken down into pyruvate
Glycolysis
Process where fatty acid chains are broken from their glycogen backbone?
Lipolysis
Can occur without oxygen present
Anaerobic
Cannot occur unless oxygen is present
Aerobic
- Readily available energy
- Low cost but guaranteed reward
- Ends in 30 ATP
- The body uses these first and most easily
Carbs/Glucose
- Stored energy
- 144 ATP produces
- High cost and high reward
Lipids/Triglycerides
Where does glycolysis occur?
Cytosol
Where do the Krebs cycle and electron transport chain occur?
Mitochondria
In an anaerobic environment, what it pyruvate converted to?
Lactic Acid
What is the net ATP for glycolysis?
2 ATP
Produces 4 but costs 2
The body uses these as the last resort for energy
Proteins
Type of reaction that is building
Anabolic
Type of reaction that is breaking down
Catabolic
What are the products of one turn of the Krebs cycle?
1 ATP
1 NADH
1 FADH2
Where does everything metabolism (cellular respiration) take place?
In the cell
The breakdown of fatty acids, by alpha and beta pairs, at the cost of 1 ATP each
Beta-Oxidation
Amino acids can be broken down into three things, what are they?
- Glucose
- Ketone bodies
- Acetyl-CoA
How many Acetyl-CoA can the body process at a time?
1
What do ketone bodies do to the blood?
Lower PH
What happens to pyruvate in an aerobic environment?
It turns into Acetyl-CoA and is sent into the Krebs cycle
