Question 6b
Many individuals with diabetes rely on a biosensor to monitor glucose levels in their blood. This biosensor uses an enzyme called __________, which is __________ onto a small pad. Through its action, the enzyme converts glucose into gluconolactone and __________. An electrode within the biosensor generates a small __________ current, and the strength of this current is __________ to the amount of glucose present in the blood. The biosensor’s meter reads this current and provides a measurement of blood glucose levels. If this measurement is above the normal range, the individual may need to take __________ to help lower it.
Many individuals with diabetes rely on a biosensor to monitor glucose levels in their blood. This biosensor uses an enzyme called glucose oxidase, which is immobilized onto a small pad. Through its action, the enzyme converts glucose into gluconolactone and hydrogen peroxide. An electrode within the biosensor generates a small electric current, and the strength of this current is proportional to the amount of glucose present in the blood. The biosensor’s meter reads this current and provides a measurement of blood glucose levels. If this measurement is above the normal range, the individual may need to take insulin to help lower it.
