Identify the reaction in which alcohol is formed by breakdown of sucrose in presence of an enzyme zymase:
Correct answer: A. Fermentation
- A. Fermentation
- B. Inversion
- C. Esterification
- D. Rearrangement
Explanation
Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol.In this case, sucrose is broken down into glucose and fructose by the enzyme Invertase.The glucose and fructose are then converted into ethanol and carbon dioxide by the enzyme Zymase. Therefore, fermentation is the correct answer because it involves the breakdown of sucrose into glucose and fructose by invertase, followed by the conversion of glucose and fructose into ethanol and carbon dioxide by zymase. The fermentation reaction is:C12H22O11 + H2O → 4C2H5OH + 4CO2

About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
