Compared to unmyelinated axons, myelinated axons?
Furkat [3]

Answer:

A. Conduct impulses faster.

Explanation:

Myelinated axons are called that way due to the myelin sheath that surrounds them. Myelin has an insulation property so electrical impulses cannot travel through it, except on certain sites called Nodes of Ranvier. In order for electrical impulses to be conducted on myelinated axons they must "jump" from one Node of Ranvier to the next, and thus conduction is faster. This is called saltatory conduction.

In the context of protein digestion, protein breakdown into its amino acid constituents is completed by?
Artemon [7]

In the context of protein digestion, protein breakdown into its amino acid constituents is completed by <u>proteases </u><u>produced in the small intestine</u>

<u />

  • Protein-degrading enzymes are referred to as proteases. These enzymes are produced by bacteria, fungus, plants, and mammals.
  • Proteins in the body or on the skin are broken down by proteolytic enzymes.
  • This may aid in digestion or the breakdown of proteins that contribute to inflammation and pain.
  • The small intestine, pancreas, and stomach all manufacture protease.
  • The stomach and small intestine are where the majority of chemical reactions take place.
  • Pepsin is the primary digestive enzyme that targets proteins in the stomach.
  • Proteases are released by the pancreas into the proximal small intestine, where they combine with proteins that have already been altered by gastric secretions and break them down into amino acids, which are then absorbed and utilized by the body as necessary.
