Question

The following process takes place in an organism X.

Glucose → Ethyl alcohol + Carbon dioxide

Identify the organism X.

• A. Hydra
• B. Yeast
• C. Euglena
• D. Humans

Answer 1

The correct option is B Yeast

There are two types of respiration in organisms:
a) Aerobic respiration
b) Anaerobic respiration
a) Aerobic respiration: The process of respiration in which an organism uses oxygen to completely break down the glucose to form energy along with water and carbon-dioxide as by products.
Eg: Humans, Plants
b) Anaerobic respiration: The process of respiration which takes place in the absence of oxygen in which glucose is partially broken down to form energy along with ethyl alcohol(in lower plants and microorganisms) and carbon-dioxide as by products.
Eg: Yeast
