Question

$5$ Glucose molecules aerobically respired and another $5$ anaerobically. What will be the total no. of ATP and $CO_2$ evolved?

• A. 180 and 10 respectively
• B. 10 and 180 respectively
• C. 36 and 2 respectively
• D. 2 and 36 respectively

Answer 1

Answer: (A)

Anaerobic respiration makes a total of 2 ATP. Aerobic respiration is much more efficient and can produce up to 38 ATP with a single molecule of glucose.
$C _{6} H _{12} O _{6} \longrightarrow 6 CO _{2}+6 H _{2} O +6 O _{2}+38 ATP$
Anaerobic respiration
$C _{6} H _{12} O _{6} \rightarrow 2$ Ethyl alcohol $+2 CO _{2}+2$
$ATP$ (as in yeast)
