2.1

Question 1

Glucagon

Answer 1

A protein hormone secreted by pancreatic endocrine cells that raises blood glucose levels; a hormone to insulin

Question 2

Glucose Tolerance Test

Answer 2

A test of the body’s ability to metabolize glucose that involves the administration of a measured dose of glucose to the fasting stomach and the determination of blood glucose levels in the blood or urine at intervals thereafter and that is used especially to detect diabetes.

Question 3

Homeostasis

Answer 3

The maintenance of relatively stable internal physiological conditions (as body temperature or the pH of blood) in higher animals under fluctuating environmental conditions.

Question 4

Hormone

Answer 4

A product of living cells that circulates in blood and produces a specific, often stimulatory, effect on the activity of cells that are often far from the source of the hormone.

Question 5

Insulin

Answer 5

A protein hormone secreted by the pancreas that is essential for the metabolism of carbohydrates and the regulation of glucose levels in the blood.

Question 6

Negative Feedback

Answer 6

A primary mechanism of homeostasis, whereby a change in a physiological variable that is being monitored triggers a response that counteracts the initial fluctuation.

Question 7

Positive Feedback

Answer 7

Feedback that tends to magnify a process or increase its output.

Question 8

Type 1 Diabetes

Answer 8

Diabetes of a form that usually develops during childhood or adolescence and is characterized by a severe deficiency of insulin, leading to high blood glucose levels.

Question 9

Type 2 Diabetes

Answer 9

Diabetes of a form that develops especially in adults and most often obese individuals and that is characterized by high blood glucose resulting from impaired insulin utilization coupled with the body’s inability to compensate with increased insulin production.

Question 10

How do insulin and glucose bind

Answer 10

Insulin does not bind directly to glucose

Question 11

Lifestyle choices for a diabetic

Answer 11

Food and drink choices and to take medications appropriately checking the amount of glucose in your blood .

Question 12

Examples of Homeostasis

Answer 12

This affects blood sugar levels and water regulations which are vital to the human body .
Glucose in the bloodstream must maintain stable to ensure the person remains healthy .

Question 13

How could Camilla being type 1 lead to her death ?

Answer 13

It could have lead to her death because if she did not take her insulin shot which could make her blood sugar levels drop which could have made her pass out and fall on the table which was found at the crime-scene tipped over .

Question 14

Feedback example

Answer 14

Recognize that blood glucose levels are regulated by the feedback action of the hormones insulin and glucagon.
