Question 29
H

A student uses the equation C6H12O6+6O2→6CO2+6H2O\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2 \rightarrow 6\text{CO}_2 + 6\text{H}_2\text{O}C6​H12​O6​+6O2​→6CO2​+6H2​O . Which interpretation of the equation is correct?

[1]
A

Glucose is oxidised completely, so more energy is transferred than in muscle anaerobic respiration

B

Glucose is oxidised incompletely, so less energy is transferred than in yeast fermentation

C

Oxygen is produced from glucose, so energy transfer continues only when light is available

D

Carbon dioxide is reduced to glucose, so the reaction supplies material for protein synthesis
