A moistens food and forms a bolus b contains.

Which is not true of enzymes. Are sensitive in their action. The correct option is c enzymes do not possess nucleophillic groups. The enzyme activity decreases with slight decrease or increase from the optimum temperature.

(b) they are made of fat and sugar. The basic purpose of enzymes is to speed up chemical reactions by providing activation energy to the substrate. They are made of fat and substrate c.

It lowers the activation energy and converts the reactants into substrate. Hence statement c is incorrect. Enzymes are made up of proteins which accelerates the rate of the reaction.

Which is not true of enzymes? Enzymes help speed up chemical reactions in the body. A) enzymes catalyse a chemical reaction by stabilising the transition state, thereby lowering the activation.

They act on specific substrate b. (2) enzymes provide no energy for the reaction, except collision energy; They act at specific ph.

It lowers the activation energy and converts the reactants into the substrate. Enzyme catalysis is dependent on the three. They act at specific temperature d.
