Answer 1

"It reacts with water" is incorrect I took the test and got it wrong. I believe it is B, because oxygen combines with glucose and makes carbon dioxide.

Answer 2

cellular respiration the starting compounds are glucose and oxygen and the ending compounds are carbon dioxide, water, and energy.

C6H12O6+6O2-->6CO2+6H2O+ energy

Glucose (sugar)+oxygen--> Carbon Dioxide+ water+energy

so It is one of the starting compounds
