Beta Oxidation Flashcards
What is beta oxidation?
Beta oxidation is the breakdown of fat for energy
What is the overall energy yield of ATP from palmitic acid (16C)?
The overall energy yield of ATP from palmitic acid is 106.
How much ATP is invested in the activation step?
2 ATP are invested in the activation step
Where does beta oxidation occur?
Beta oxidation occurs in the mitochondria
What are the products of beta oxidation?
The products of beta oxidation are:
*Acetyl Coenzyme A
* FADH2
*NADH
Where do FADH2 and NADH feed into?
FADH2 and NADH feed into the electron transport chain
When is beta oxidation the preferred form of metabolism?
Beta oxidation is the preferred form of metabolism during starvation and endurance exercise.
A saturated fat has _____ bonds
A saturated fat has single bonds
An unsaturated fat has at least 1 _________ bond
An unsaturated fat has at least 1 double bond.
What are the three steps for use of fats as energy?
- Mobilisation
- Activation
- Beta oxidation
Kinases ____ phosphates, phosphatases _____ phosphates.
Kinases ADD phosphates, phosphatases REMOVE phosphates.
To travel around the body, which protein is free fatty acids bound to?
To travel around the body, free fatty acids are bound to albumin
What are lipoproteins made up of? PPTS
Lipoproteins are made up of: proteins, phospholipids, triglycerides and sterols.
What are the four types of lipoproteins?
The 5 types of lipoproteins are: LDL, HDL, VDL, IDL and chylomicrons
Describe mobilisation
Mobilisation: degradation of a TAG to fatty acid and glycerol
