Tell me the four lipoproteins we discussed
Where are they made, where do they go, what do they deliver?
Chylomicron- made in SI cells, go to lymph, then drop TG into blood
VLDL- made in liver, goes to cells and deliver TG
LDL- converted from VLDL, delivers cholesterol to cells

What is the purpose of calculating the area under the curve of a glucose tolerance test rather than just looking at the peak?
Gives us a better idea of how long glucose stays elevated compared to just the top spike

Lol. How do we get browning of adipose tissue? I want SPECIFICS here
Muscle contract and release myokines, myokines go to the blood and travel to adipose tissue, leads to reduction in TG droplet and more mitochondria formation
