Are the exogenous and endogenous pathways for ldl/vldl/hdl different?

No, they are the same

Explanation:

Exogenous Way

Through the diet we provide the body with various  lipid particles (TG, cholesterol, phospholipids). The action of  different digestive enzymes next to bile salts, forces  intestinal mechanics (peristalsis), and the ionizing effect of pH,  complete the digestion process of most lipids, transforming them into micelles capable of crossing the membrane  of the enterocito. Once absorbed, a process of  re-esterification of the different lipid particles, while synthesizing a series of proteins (apoproteins) that are  incorporate lipids constituting lipoproteins, form of  transport of most blood lipids. Is about  spherical particles whose nucleus consists of hydrophobic lipids (esterified cholesterol, triglycerides), surrounded by lipids  polar (phospholipids, free cholesterol). In the bark they are located  apoproteins that facilitate plasma solubility while  they act as recognition signals for the transport of lipids to different tissues, activating or inhibiting key enzymes  that regulate lipoprotein metabolism apoproteins that facilitate plasma solubility while  they act as recognition signals for the transport of lipids to different tissues, activating or inhibiting key enzymes  that regulate lipoprote metabolism.

Endogenous Way

The liver synthesizes them directly or from circulating lipoproteins (remnants of QM). The apoprotein that characterizes them is BIOO. These lipoproteins are rapidly degraded by lipases similar to those of the QM losing a large amount of TG and surface apoproteins, transforming into IDL intermediate density lipoproteins (30% cholesterol, 40% TG)

They can be picked up by the liver, which will extract your cholesterol to make more VLDL and for other cell needs  liver, or may remain in circulation longer until  they lose apo E and become LDL.

HDL are synthesized in the liver and intestine initially with a discoidal form, containing non-esterified cholesterol, phospholipids and apoproteins, mainly apo A (Al and A2). These nascent HDLs take cholesterol from the tissues (interchangeable with  be more superficial) transforming into spherical particles.

the statements that apply here about binary star system are

"have stars that might appear to wobble"

"often have one star that is brighter than other"

a binary star is a star system consisting of two stars revolving around their common barycenter. systems of two or more stars are called multiple star systems.
