Question

during cellular respiration, the carbons initially present in pyruvate are derived from __________ and are ultimately converted to __________. acetyl-coa; co₂ nad⁺; atp glucose; co₂ and acetyl-coa glucose; atp i dont know yet

Explanation:

Cellular respiration starts with glucose. Glucose is broken down into pyruvate in glycolysis. Then, in the citric acid cycle (Krebs cycle), the carbons from pyruvate (originally from glucose) are further processed and ultimately released as \(CO_2\). Acetyl - CoA is an intermediate, not the final form of carbon release. \(NAD^+\) is a co - enzyme, and ATP is the energy currency, not the carbon - containing end - product.

Answer:

glucose; \(CO_2\) and acetyl - CoA
