PLTW Biomedical Science Unit 2 ACTUAL
UPDATED QUESTIONS AND CORRECT
ANSWERS
Glucagon - CORRECT ANSWERS✅✅protein hormone that raises blood sugar levels;
antagonistic to insulin
Glucose Tolerance Test - CORRECT ANSWERS✅✅tests the body's ability to metabolize
glucose when a dose of glucose is taken into the stomach. Then the glucose level is
determined and detects diabetes.
Homeostasis - CORRECT ANSWERS✅✅maintenance of stable internal physiological
conditions
Hormone - CORRECT ANSWERS✅✅a product of living cells that circulates in blood and
produces a stimulating effect on cells
Insulin - CORRECT ANSWERS✅✅protein hormone secreted by pancreas that is essential
for the breakdown of glucose in the blood
Negative Feedback - CORRECT ANSWERS✅✅homeostasis; a variable that fluctuates the
initial (balance)
Positive Feedback - CORRECT ANSWERS✅✅feedback that increases its output
Type 1 Diabetes - CORRECT ANSWERS✅✅diabetes that develops during childhood and
doesn't have enough insulin
Type 2 Diabetes - CORRECT ANSWERS✅✅diabetes that develops in adults and often in
obese individuals; the body is unable to cooperate with the insulin on the glucose
ATP - CORRECT ANSWERS✅✅supplies energy for cellular processes
, Dehydration synthesis - CORRECT ANSWERS✅✅water is used to break apart 2 molecules
Ionic Bond - CORRECT ANSWERS✅✅bond where there is an attraction between opposite
charged atoms
A young patient has an increased thirst and is very fatigued (no energy). The doctors tell the
patient that their pancreas is not functioning properly. This patient most likely has
______________. - CORRECT ANSWERS✅✅Type 1 Diabetes
What is negative feedback? - CORRECT ANSWERS✅✅A response to a change in the body
that counteracts or opposes the initial change.
What is positive feedback? - CORRECT ANSWERS✅✅Feedback that increases the output
of a process.
What is an example of positive feedback? - CORRECT ANSWERS✅✅Blood clotting. The
initial clotting triggers the formation of more clots.
What is an example of negative feedback? - CORRECT ANSWERS✅✅Insulin response to
high blood sugar. If blood sugar rises, insulin is released to lower blood sugar.
An out of shape, overweight adult is told that they have developed diabetes. The patient most
likely has ______________. - CORRECT ANSWERS✅✅Type 2 diabetes.
In Type 1 diabetes, the pancreas does not produce ______________. - CORRECT
ANSWERS✅✅Insulin
What explains the high blood sugar that results from Type 2 diabetes? - CORRECT
ANSWERS✅✅The pancreas makes insulin, but it is not used effectively by the cell.
A protein hormone released by the pancreas used to control blood glucose levels. -
CORRECT ANSWERS✅✅Insulin.
