How would you explain the connection between glucose entering the body and energy created by the body to a friend, using your new biochem knowledge

I would use my biochemistry knowledge to explain that for every molecule of glucose, 30 ATP are produced, which is what our bodies uses as energy. A molecule of glucose is transition to ATP with glycolysis. First 2 ATP are “invested” into the process and through 10 steps, a net of 2 ATP are produced, as well as 2 NADHs. The product of glycolysis in addition to the ATP is pyruvate. The pyruvate is next converted to Acetyl CoA (with 2 NADH as byproduct) in the inner mitochondrial matrix and once that has occur, the citric acid cycle occurs in the mitochondrial matrix and through 8 steps 2 FADH2 and 6 NADH are produced, as well as 2 ATP. The NADH and FADH2 that were produced from glycolysis, inner mitochondrial matrix, and the citric acid cycle are reoxidized into 26 ATP during electron transport and oxidative phosphorylation.
