Physical Activity And Cvd Risk Factors: Lipoprotein Metabolism

Question 1

Cvs risk factors:

Answer 1

UnChangeable: gender age race family history

Changeable: smoking, inactivity, obesity, diet

Question 2

Describe the different types of lipoproteins

Answer 2

Chylomicrons and very low density lipoproteins are rich in TAG

low density lipoproteins are rich in cholesterol

High density lipoprotein are rich in protein and phospholipid

Question 3

Effect of tg rich vldl on lipoprotein profiles:

Answer 3

1.VLDL increases. So too does their cholesterol content this increased delivery of cholesterol to vessel walls

2. Fewer HDL particles to engage in reverse cholesterol transport
3. Transfer of HDL cholesterol to VLDL results in less reverse cholesterol transport

Question 4

Exercise and ppl summary

Answer 4

A brisk walk reduces TAG response after a moderate fat meal this could be driven by a number of mechanisms:
1.greater LPL activity to restore intramuscular TAG
2. Greater blood flow to previously exercised muscle and the liver
