Question

Consider the following chemical reactions which take place in different organisms/tissues under various conditions:
(i)$\text{Glucose}\stackrel{\text{Respiration}}{\to }\text{Ethanol}+\text{Carbon dioxide}+\text{Energy}$
(ii)$\text{Glucose}\stackrel{\text{Respiration}}{\to }\text{Carbon dioxide}+\text{Water}+\text{Energy}$
(iii) $\text{Glucose}\stackrel{\text{Respiration}}{\to }\text{Lactic acid}+\text{Energy}$

(b) Name one organism which respires according to equation (ii) above.

Answer 1

Answer:
Human beings respire according to equation (ii).

The by-products of the reaction are water and carbon dioxide, both of which are eliminated as waste products and energy is generated.
