Question

How many ATP are produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to $C{O}_2$ and $H_{2}O$? $(18.4 ,18.5 ,18.6)$

Step-by-Step Solution

Answer

$32$ATP is produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to $C{O}_2 and H_{2}O$.

Step 1: Given Information

We need to find the ATP that is produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to  $C{O}_2 and H_{2}O$.

Step 2: Simplify

The ATP produced in the oxidation of glucose to pyruvate yields only $7 ATP$ units. Presented below is the ATP yield of the oxidation of glucose to pyruvate.

Now, the complete oxidation of glucose to carbon dioxide$32 ATP$ is produced. When glucose enters glycolysis, $7 ATP$  is produced. As it undergoes oxidation, the product of glycolysis is oxidized and decarboxylated to acetyl CoA yielding $5 ATP$ . When acetyl CoA proceeds to the citric acid cycle, acetyl CoA is further complete oxidation of glucose to carbon dioxide.
