Question

UESTIONS this exercise. to some of the following questions will be found in Exercise 26; the remainder are located i Enzymes that are made by the cell and released into the surrounding medium are called Hydrolytic enzymes are so named because they insert the polymer as it is broken. Extracellular hydrolytic enzymes that break down proteins are break down polysaccharides are called- lipids are called Assume that a polymer outside the cell has been broken down by the appropriate enzymes molecules can get into the cell, at least two proteins in the plasma membrane must be across the covalent bond in Those that called . and those enzymes that break down as and Before the smaller present. These are and the proteins The type of covalent bond that connects adjacent sugars making up a polysaccharide is called a bond. An example of a nutrient One example of a structural polysaccharide is Amylose is an enzyme that attacks starch. The smallest product of this hydrolysis is called This effect is produced Starch hydrolysis is evident on starch plates by bocause The chemical used to detect microbial starch hydrolysis on starch plates is True-False (correct all false statements) 1. A molecule must get into a cell before the cell can use it as a source of energy, 2. The ability to produce and release extracelilular enzymes for hydrolyzing a specific type of polymer is a property shared by all microorgasms. 3. Some small molecules transported into the cell may be used directly as building blocks for biosynthesis 4·Carbohydrates are molecules composed of three types of atoms: carbon, oxygen, and nitrogen. 5. A positive starch-hydrolysis test is indicated by a blue zone surrounding the area of growth on a starch plate treated with merthiolate. 6. Of the two hbacteria tested in this exercise, only the species of Bacillus gives a strong positive reaction.

Explanation / Answer

Enzymes that are made by the cell and released into the surrounding medium are called exotoxins

Hydrolytic enzymes are so named because they insert Hydrogen across the covalent bond in the polymer as it is broken.
