Is glucose an enzyme?
No. Glucose is a carbohydrate.
Since you know what Glucose Oxidase is I'm assuming you know what enzymes are. If not, an enzyme is a protein that catalyzes chemical reactions. Glucose oxidase is the enzyme built specifically for Glucose. Glucose Oxidase binds to the six-carbon sugar Glucose and aids the organism in breaking it down into metabolites.
Actually, the enzyme amylase converts the starch to maltose. Enzyme maltase then converts maltose to glucose + glucose. Whilst enzyme sucrase converts sucrose to glucose + fructose and enzyme lactase converts lactose to glucose + galactose. So, glucose is actually the end product. Well, anyways, back to your question. The only reason they breakdown the sugars is because they need to use it up to take in the energy. They must be in their sinplest…
There is no enzyme that assists in the breakdown (digestion) of glucose like you would see in sucrose (a disaccharide sugar). Glucose is a monosccaharide and is generally used in the body to make ATP in the glycolysis pathway. In this path glucose is used to make 2 net ATP. The first step in this path hexokinase is the enzyme that acts as the catalyst to phosphorylate glucose to glucose-6-phosphate. If you are asking about…
An enzyme speeds up a chemical reaction. Therefore, once an enzyme has carried out it's function, it moves onto the next reaction. For example, the enzyme maltase speeds up the synthesis of maltose from two glucose molecules. Once the enzyme has carried out the synthesis of maltose, it then moves onto another glucose to maltose reaction. Enzymes do not "wear out."
Insulin is an enzyme produced by the pancreas that allows glucose to pass from the blood through the cell walls so that it can be used by the cells for energy. By assisting the removal of glucose from the blood, it (along with an enzyme called glucagon, produced by the liver) controls glucose levels in the blood.
