Question

Which process is responsible for the making of bread and wine?

• A. Filtration
• B. Fermentation
• C. Sedimentation
• D. Leavening

Answer 1

The correct option is B Fermentation

Fermentation is an enzyme catalysed metabolic process, where organisms (such as yeast and bacteria) convert sugars to alcohol or an acid anaerobically and release very little energy.

For making bread, baker’s yeast is used. Under anaerobic conditions, yeast undergoes fermentation. The yeast converts the carbohydrates in the bread dough into ethanol and releases carbon dioxide gas. The carbon dioxide makes the dough rise. This is called leavening of bread.

Hence, the process responsible for the making of bread and wine is fermentation.

Filtration is defined as the process of separating solid matter suspended in a liquid, by passing through the pores or a membrane, called a filter.

Sedimentation is another simple separation method used to separate particles based on their size.
