Ingested Foods Inside the Digestive Tract of Snakes are Typically

Question

Ingested foods inside the digestive tract of snakes are typically digested by
A) biosynthesis.
B) enzymatic hydrolysis.
C) uric acid.
D) chemiosmosis.
E) metabolic heat.

Accepted Answer

Enzymatic hydrolysis is the process by which enzymes break down foods into their smaller components (such as proteins into amino acids) that can be absorbed by the body. This is the primary mechanism by which snakes digest their food.

Choice A (biosynthesis) is the process of creating new molecules from simpler ones, and is not typically involved in digestion. 
Choice C (uric acid) is a waste product of protein digestion/excretion, but does not play a direct role in the breakdown of food. 
Choice D (chemiosmosis) is a process by which ATP is produced in the mitochondria, and is not directly related to digestion. 
Choice E (metabolic heat) may aid in digestion for some cold-blooded animals, but is not a primary mechanism by which snakes digest their food.
