A) amylase
B) gastric juices
C) lysozyme
D) lactate
E) DNAase

Accepted Answer

Lysozyme is an enzyme that breaks down bacterial cell walls and can be found in most epithelial tissue secretions, such as tears, saliva, and mucus. Amylase is an enzyme that breaks down carbohydrates, gastric juices are found in the stomach and help with digestion, lactate is a byproduct of anaerobic respiration, and DNAase breaks down DNA.
