48. Which of the following statements correctly explains the relationship between lipoproteins and cardiovascular disease risk?
(A) High-density lipoproteins (HDL) facilitate the transport of triglycerides from adipose tissue to the liver.
(B) Low-density lipoproteins (LDL) are responsible for cholesterol uptake by peripheral tissues, and an elevated LDL/HDL ratio is associated with an increased risk of atherosclerosis.
(C) Very-low-density lipoproteins (VLDL) transport dietary cholesterol to skeletal muscle for metabolism.
(D) Cholesterol homeostasis is primarily regulated by renal excretion rather than hepatic processing.
(E) Increased LDL uptake by hepatocytes is directly regulated by epinephrine binding to ẞ-adrenergic receptors.
