Explanation:
A physical change alter a given material without changing its chemical
Oxidation of D-glucose are usually found on the photosynthesis which has a by product of carbon dioxide (CO2) and water (H2O) chemically written as,
C6H12O6 +6O2----> 6CO2 +6H2O
Moreover, D-glucose can also be chemically react with oxygen to form D-gluconic acid and D-glucoronic acid.
The 3 properties of enzymes are specific reaction, or specific type of reaction, that involves specific substrates.
