Question

Oxygen is necessary for complete oxidation of glucose ​

Answer 1

Answer:

Absence of oxygen during glucose breakdown produces pyruvic acid and alcohol. ... Presence of oxygen during aerobic breakdown of glucose produces water and carbon dioxide along with the release of a large amount of energy. Hence, oxygen is necessary for the complete oxidation of glucose

Explanation:

Answer 2

Answer:

• All living organism requires energy to live and to perform any useful functions.  
• This energy they get from food they eat. Energy is released when food contains nutrients, let’s say carbohydrate (glucose).  
• Energy released in the cells when oxidation of glucose occurs which means the carbohydrates which we eat converted into simpler substances with the help of oxygen.  
• For complete oxidation of glucose (i.e the breakdown into simpler substances) oxygen is necessary.
