Which of the following is NOT a function of low-density-lipoproteins (LDLs)?

Select the description below that illustrates a difference between a sphincter and
circular muscle.
(a) Sphincters are found in the proximal portion of the GI tract while circular muscle is
found in the distal portions

digesting materials while circular muscle is involved in propulsion digesting materials

(a) The cells producing inactive enzymes are themselves protected from the enzymes
until they are safely within the lumen of the GI tract

regulation of protein-digesting enzymes
