Question

${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\to {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+{\mathrm{CO}}_2+\mathrm{Energy}\mathrm{is}$

• A. Respiration reaction
• B. Anaerobic reaction
• C. Aerobic reaction
• D. Photosynthesis reaction

Answer 1

The correct option is B

Anaerobic reaction

The correct option is B.

Explanation for the correct option:

1. Anaerobic reaction causes the breakdown of glucose to produce ethyl alcohol, carbon dioxide and energy.
2. Such a type of reaction is called fermentation.

Explanation for the incorrect options:

Option A:

1. Respiration reaction involves the presence of oxygen.
2. The products obtained in a respiration reaction are carbon dioxide, water and energy.
3. Ethyl alcohol is not a product of such a reaction.

Option C:

1. Aerobic reaction involves the presence of oxygen.
2. The final product in aerobic respiration is therefore not ethyl alcohol.

Option D:

1. Photosynthesis reaction takes place in presence of carbon dioxide, water and sunlight.
2. The products of photosynthesis are glucose and oxygen.
3. Glucose does not break down into ethyl alcohol in photosynthesis.

${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6\to {\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}+{\mathrm{CO}}_2+\mathrm{Energy}\mathrm{is}$ an anaerobic reaction.
