Microbial Biochemistry Exoenzymes

These flashcards cover key vocabulary and concepts from the Microbial Biochemistry lecture on exoenzymes and their functions.

Biochemistry

The chemical reactions that occur in a cell.

Exoenzymes

Enzymes secreted outside of the cell to hydrolyze macromolecules into smaller monomers.

Substrate

The substance on which an enzyme acts; for DNase, it's DNA.

Nuclease

An enzyme that hydrolyzes nucleic acids, like DNase for DNA.

Protease

An enzyme that breaks down proteins into smaller peptides or amino acids.

Lipase

An enzyme that hydrolyzes lipids into fatty acids and glycerol.

Amylase

An enzyme that breaks down starch into glucose and maltose.

Differential Media

Media that allows for the differentiation of microorganisms based on specific biochemical reactions.

Hemolysins

Exotoxins produced by some bacteria that can destroy red blood cells.

Starch Agar Plate

A media used to test the ability of microorganisms to hydrolyze starch.

DNase Test

A test to determine if a microorganism can hydrolyze DNA.

Caseinase

An exoenzyme produced by some bacteria that hydrolyzes casein in milk.

Tributyrin

A type of triglyceride, a lipid substrate hydrolyzed by tributyrinase.

Gelatinase

An enzyme that hydrolyzes gelatin into amino acids.
