Sucrose is made up of glucose and fructose. If it is acted upon by the enzyme invertase and the resulting monosaccharides are further oxidized through the respiratory pathway, what will be the respiratory ratio in this case?
Text Solution
Verified by ExpertsThe correct answer is:
C
Sucrose → a disaccharide made of glucose + fructose. Enzyme invertase hydrolyses sucrose into its monosaccharide components. Both are carbohydrate. When carbohydrates are used as substrate and are completely oxidised, the RQ will be 1, because equal amounts of 
and 
are evolved and consumed.
