Fermentation | MCQs

Explanation

 Glycolysis is the initial stage of both fermentation and cellular respiration, breaking down glucose into pyruvate and generating a small amount of ATP and NADH, regardless of whether oxygen is present. 

Explanation

Carbon Dioxide is responsible for fermentation.

During fermentation, microorganisms like yeast convert sugars into alcohol and carbon dioxide as byproducts.

Explanation

Ethanol (C₂H₅OH) is oxidized to ethanoic acid (CH₃COOH) using oxidizing agents like acidified potassium dichromate (K₂Cr₂O₇).

This chemical reaction involves the gain of oxygen or loss of hydrogen, which defines oxidation.

Explanation

Respiration in Pseudomonas bacteria is aerobic.

These bacteria primarily use oxygen as the terminal electron acceptor in their respiration process.

Although some species can also perform anaerobic respiration under certain conditions.
