nad⁺; atp
i dont know yet

Explanation:

During glycolysis, glucose is broken down into pyruvate. So the carbons in pyruvate initially come from glucose. In the citric acid cycle (a part of cellular respiration), the carbons in acetyl - CoA (which can be derived from pyruvate) are ultimately converted to \(CO_{2}\).

Answer:

glucose; \(CO_{2}\)
