What is fermentation - Being able to grow anaerobically in the presence of a suitable organic compound, such as a sugar. Several reduced products are excreted by the cell as a way of disposing of the electrons derived from oxidation. Function and Types of hydrolytic enzymes - Hydrolytic enzymes hydrolyze (break down) complex molecules to get food that can be transported into the cell. 1. Amylase 2. Caseinase 3. Gelatinase Amylase - catalyzes starch hydrolysis. Reacts readily with iodine...
