Can dextrose produce more CO2 because it s a 6-carbon structure? Can fructose produce more because it s a ketone?Or dextrose as an aldehyde?

I am doing a fermentation experiment. I am comparing dextrose (a form of glucose) and fructose to see which will produce more CO2 during fermentation. I need to know how their structure affects the amount of CO2 produced.

Both dextrose and glucose have the same molecular formula C₆H₁₂O₆. Hence, they have the same equation for the reaction in fermentation as follows:
C₆H₁₂O₆ → 2CH₃CH₂OH + 2CO₂
Therefore, when equal amounts of dextrose and fructose undergo complete fermentation, equal amounts of CO₂ are produced. The structure of the monosaccharide does not affect the amount of CO₂ produced.
C₆H₁₂O₆ → 2CH₃CH₂OH + 2CO₂
Therefore, when equal amounts of dextrose and fructose undergo complete fermentation, equal amounts of CO₂ are produced. The structure of the monosaccharide does not affect the amount of CO₂ produced.

In metabolism glucose is isomerized to fructose in the first metabolic step. This means that both are consumed in exactly the same way. Both give 2 molecules of CO2 in fermentation.
