What are the reactants and products of respiration?

2 Pruvate

reactants: glucose and oxygen product: carbon and water

Simplified, it's: C6H12O6 + O2 --> H2O + CO2

G: Glucose + 2 NAD+ + 2 ADP + 2 Pi → 2 NADH + 2 pyruvate + 2 ATP + 2 H2O + 2 H+ input = Glucose, NAD+, ATP => also (+) coenzyme A? output = Pyruvate, NADH, net ATP => Acetyl CoA + CO2 + more...

Glucose and oxygen reactants while carbon dioxide and water are products .
