Vedclass · Answer

(A) The $R.Q.$ (Respiratory Quotient) is defined as the ratio of the volume of $CO_2$ evolved to the volume of $O_2$ consumed during respiration.When a cell is starving,it has exhausted its carbohydrate reserves and begins to respire using proteins or other organic acids as respiratory substrates.However,in a state of extreme starvation,the cell may stop consuming $O_2$ while still releasing $CO_2$ through anaerobic processes or decarboxylation,or the metabolic processes become highly irregular.In many biological contexts,the $R.Q.$ of a starving cell is considered to be zero because the cell stops taking in oxygen while metabolic activities continue to produce $CO_2$ or because the respiratory substrate is completely depleted.

The $R.Q.$ value of a starving cell is ......... .
