Question

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

Explanation:

Cellular respiration starts with glycolysis where glucose is broken down into pyruvate. Then pyruvate is converted to acetyl - CoA (losing one \(CO_2\) molecule in the process in eukaryotes). In the citric acid cycle, acetyl - CoA is further oxidized and the carbons are ultimately released as \(CO_2\).

Answer:

acetyl - CoA; \(CO_2\)
