Answer:
See the answer below
Explanation:
a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1 falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.
b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.
c) The hormone that person 3 cannot produce is insulin.
Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.
