Question

Zymase is used to catalyse the hydrolysis of glucose.
(a) True
(b) False

Answer 1

Hint: Hydrolysis reaction is opposite of dehydration reaction. In dehydration reaction, water is formed but in hydrolysis, water is used to carry out a particular reaction. Zymase is a type of enzyme which can catalyse the reaction to take place.

Complete step by step answer:
(1) Glucose is a type of sugar. It has a chemical formula ${C_6}{H_{12}}{O_6}$. Hydrolysis is a process where polymers are broken down into their constituent units called the monomers using a water molecule.
(2) Catalyzation is a process done by catalysts, which help the reaction to take place by lowering the activation energy of the reactant. Activation energy is the minimum energy needed to carry out a reaction. Catalysts do not change during the reaction; they remain indestructible after the product is formed.
(3) Zymase is an enzyme obtained from a living microorganism called yeast. This zymase is used to carry out the fermentation of glucose to break the chemical bonds of the glucose to form alcohol, and carbon dioxide.
(4) Fermentation is an anaerobic process, which means that it takes place in the absence of oxygen, zymase works on the simple sugar, and converts it into alcohol, and carbon dioxide gas along with release of energy.
Hence,the given statement is true.

Note:
Fermentation reaction is needed to be carried out in the absence of oxygen which is called anaerobic respiration because if oxygen is present, then it will form ethanoic acid in place of ethanol. This will ruin the quality of the product of alcohol.
