Question

Consider the following statement
I. Yeast used in making bread and beverages is a prokaryotic fungus
II. Streptokinase is produced by streptococcus and modified by gentic engineering is used as a clot buste
III. Lipases are added in detergent for removing stains from laundry
IV. Pectinases are used in clearing fruit juices
Which of the statement given above are correct?

• A. I, II, III and IV
• B. I, II and III
• C. II, III and IV
• D. III and IV

Answer 1

The correct option is C II, III and IV

I. Yeast is the fungus consisting of membrane-bound organelles, whereas in the prokaryotic system do not contain membrane-bound organelles.

II. The enzyme streptokinase is produced by the organisms streptococcus. It is extensively used in the blood clot buster.

III. Detergents are added within the enzymes in order ease the process of stain removal, as the stains are comprised of oils, grease, proteins and oils. Lipase enzyme breaks down fats and oils. So they are used in stain removal for laundry purposes.

IV. The pectinases enzyme is used in the clearing of fruits, as these enzymes help in the breakdown of polysaccharide pectin present in the cell wall of plants to galacturonic acid monomers. Hence the pectin structure breakage facilitates filtration and high yield of juice.

Therefore the right answer is option "C, II, III and IV".
