Question

Consider the following chemical reactions which take place in different organisms/tissues under various conditions:

(i) Glucose $R e s p i r a t i o n - ------ \to$ Ethanol + Carbon dioxide + Energy
(ii) Glucose $R e s p i r a t i o n - ------ \to$ Carbon dioxide + Water + Energy
(iii) Glucose $R e s p i r a t i o n - ------ \to$ Lactic acid + Energy

(a) Name one organism which respires according to equation (i) above.

Open in App

Solution

Yeast respires according to equation

(i). Anaerobic respiration is a type of cellular respiration which takes place in the absence of oxygen. During anaerobic respiration in yeast, glucose is broken down into ethanol and carbon dioxide with the release of energy.
