| 3389. |
Salivary amylase is stimulated by:(1) Na(3) HCO343.(2) K(4) CH |
| Answer» <p>(4) Cl-</p><p>Explanation:Many enzymes exist in two states, an inactive and an active state. Usually, these states differ in the confirmation, or three-dimensional shape, of the enzyme. The balance between these two states provides a means for regulating the activity of the enzyme, in effect, by turning it on or off. Often the switch that controls which state the enzyme is in is provided by a small molecule which binds to a receptor site somewhere on the surface of the enzyme. Such a small molecule is called an allosteric effector. For alpha-amylases from mammals, chloride ion is the allosteric effector. These amylases have a binding site for chloride ion, which contains a positively charged amino acid residue (lysine, which at physiological pH is in the ammonium ion form). This positive charge assists binding of the negatively charged chloride ion and the size of the binding pocket excludes larger negative ions. Binding of chloride causes a conformational change to the amylase, switching it to the more active state.</p> | |

why we human beings cannot digest cellulse? |
| Answer» <p>Humans are unable to digest cellulose because the appropriate enzymes to breakdown the beta acetal linkages are lacking. Indigestible cellulose is the fiber which aids in the smooth working of the intestinal tract. unlike cows for ex. don't have the necessary bacteria in their intestines that make the enzymes necessary to breakdown the 1-4 beta glucose bonds. So we cannot break down cellulose into its constituent glucose molecules as we do with starch.</p> <p>because we have not cellulose digesting enzyme</p> <p>we cannot digest cellulose because we don't have digestive juices like ruminants have. we are also not having stomach like them because there stomach is divided into four parts </p> | |
