PLTW Biomedical Science - Unit 2.1
Exam Questions and 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
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)
Lipid - Correct Answers -fats, phospholipids, and steroids that are insoluble in water
Macromolecule - Correct Answers -large molecule formed by smaller molecules like
protein, carbohydrates, nucleic acids, and lipids
Molecule - Correct Answers -2 or more atoms bonded together
Monomer - Correct Answers -serves as a building block of polymer
Monosaccharide - Correct Answers -single simple sugar like glucose or fructose;
simplest type of sugar
Polymer - Correct Answers -large molecule with repeating units of monomers
Polysaccharide - Correct Answers -polymer of many many simple sugars formed by
dehydration synthesis
Positive Feedback - Correct Answers -feedback that increases its output
