1.	Question : What are the different ways in which glucose is oxidised to provide energy in variousorganisms ?
Answer» Solution :Some organisms use oxygen to break-down glucose COMPLETELY into `CO_(2)`and WATER. Such a type of OXIDATION of food is called as aerobic respiration. Certain bacteria, yeast do not involve OXYGENAND glucose in incompletely oxidisedto formeither ethyl alcohol or lactic acid and `CO_(2)`. Such a type of respiration is called as anaerobic respiration. GLYCOLYSIS is a common step in aerobic as well as anaerobic respiration which occurs in cell cytoplasm. Inthis six carbon glucose molecule is broken into a three carbon pyruvic acid. The pathway of break-down of glucose in variousorganism is depicted below :
