In an investigation, two persons A and B drunk the same amount of glucose solution. Their blood
sugar levels were determined immediately and thereafter at intervals of one hour for the next six
hours.
The results were as shown in the following table

(a) Explain each of the following observations;-
(i) Blood sugar level increased in person A between 0 and 1 hour
(ii) The blood sugar level dropped in person A between 1 and 4 hours
(b) From the graph, what is the normal blood glucose sugar level for human beings
(c) Suggest a reason for the high sugar level in person B
(d) How can the high blood sugar level in person B controlled?
(e) What is the biological significance of maintaining a relatively constant sugar level in a human

(a) (i) Blood sugar level increased as a result of the glucose being absorbed in the ileum; by
diffusion / or active transport;
(ii) – The blood sugar level dropped as a result of the conversion of glucose to glycogen;
(and fats) by influence of insulin;.
- There was also an increased rate of respiration reducing the blood sugar level;
(b) 90 mg/100ml of blood;
(c) Person B has a defect in the pancreas; He did not produce enough insulin to control the
blood sugar level;
(d) By administration of insulin;
(e) - A constant level of blood sugar ensures optimum levels of metabolism;
- High level will increase the osmotic pressure and that affect metabolism;
- Low levels reduce energy supply in the body tissues and affect metabolism;
(f) - Glucose is used for respiration;
- Glucose was lost in urine;
