The Digestive System: Enzymes
| Question | Answer |
|---|---|
| albumin | a protein found in blood, egg white, etc. |
| amylase | enzyme produced by salivary glands and pancreas; catalyzes conversion of starch to the disaccharide maltose |
| assimilation | conversion of nutrients into body components |
| catalyst | an agent that alters the rate of a chemical reaction without being consumed by the reaction |
| digestion | to convert complex, insoluble molecules into simpler, soluble ones |
| egestion | to discharge or eliminate from the body |
| enzyme | cell product capable of altering the rate of reaction without being consumed by the reaction |
| ingestion | active intake of food |
| lipase | an enzyme that converts lipids into fatty acids and glycerol |
| maltase | an enzyme that converts maltose into simple sugars |
| maltose | a disaccharide ("double" sugar) |
| peptidase | a group of enzymes that convert small peptides into amino acids |
| peptide | organic molecule consisting of two or more amino acids |
| pepsin | enzyme that converts protein into smaller polypeptides |
| pepsinogen | precursor molecule that is converted into pepsin when the pH is acidic |
| starch | a complex polysaccharide; the storage molecule found in plants |
| trypsin | a pancreatic enzyme that converts polypeptides into smaller peptide units |
