Question 13
Which of the following is most appropriate for aerobic respiration?

(a) $Glucose\stackrel{mitochondria}{\to }Pyruvate\stackrel{cytoplasm}{\to }C{O}_2+H_{2}O+Energy$
(b) $Glucose\stackrel{cytoplasm}{\to }Pyruvate\stackrel{mitochondria}{\to }C{O}_2+H_{2}O+Energy$
(c) $Glucose\stackrel{cytoplasm}{\to }Pyruvate+Energy\stackrel{mitochondria}{\to }C{O}_2+H_{2}O$
(d) $Glucose\stackrel{cytoplasm}{\to }Pyruvate+Energy\stackrel{mitochondria}{\to }C{O}_2+H_{2}O+Energy$

Answer 1

The correct option is (d):

Explanation of the correct option:

1. Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of oxygen.
   
2. The word aerobic means, in air, but it is the oxygen in the air which is necessary for aerobic respiration.​
   
3. Glycolysis is the process of conversion of glucose to pyruvate in the cytoplasm, where two molecules of ATP is produced.
   
4. The rest of the processes take place in the mitochondria, in the presence of enzymes that are present inside the mitochondria, producing carbon dioxide and water along with the production of energy.
   

Final Answer: The correct equation is:

$Glucose\stackrel{cytoplasm}{\to }Pyruvate+Energy\stackrel{mitochondria}{\to }C{O}_2+H_{2}O+Energy$
