Bacteria Archea Virus And Their Broad Classification

The lactose present in the growth medium of bacteria is transported into the cell by the enzyme Permease. In the context of bacterial cells, such as E. coli, lactose transport is a part of the lactose operon system, which is crucial for the metabolism of lactose. The main components of this system include:

• Permease: This enzyme facilitates the movement of lactose across the bacterial cell membrane, allowing it to enter the cell. Once inside, lactose can be further metabolized.
• Beta-galactosidase: This enzyme hydrolyzes lactose into glucose and galactose.
• Acetylase: Part of the operon, though its direct role in lactose metabolism is less prominent compared to permease and beta-galactosidase.

In this scenario, Permease is the enzyme responsible for the transportation of lactose into the cell, ensuring the availability of lactose for further enzymatic processing and energy production within the bacterial cell.

(A) Clostridium butylicum: This microorganism is known for producing butyric acid, a short-chain fatty acid.

(B) Saccharomyces cerevisiae: This yeast is widely used in fermentation processes to produce ethanol.

(C) Trichoderma polysporum: This fungus is used in the production of cyclosporin-A, an immunosuppressant drug.

(D) Streptococcus sp.: This bacterium produces streptokinase, an enzyme used in medical treatments to dissolve blood clots.

The correct matching is shown below:

Thus, the correct match is:

Explanation:

• Clostridium butylicum is responsible for the production of butyric acid, a fatty acid used in various biochemical applications.
• Saccharomyces cerevisiae is widely employed in brewing and baking industries to produce ethanol via fermentation.
• Trichoderma polysporum produces Cyclosporin-A, an important immunosuppressant drug used in organ transplantation.
• Streptococcus sp. secretes Streptokinase, an enzyme that helps dissolve blood clots and is used in clot-busting therapies.

This concludes our solution.
