Bio 201 Exam 1 Review UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Anatomy - CORRECT ANSWER - science of body structures and the relationships among
them. First studied by dissection, now modern imaging as well
Physiology - CORRECT ANSWER - science of body functions- how it works. Much has
been gained through "comparative physiology"
Anabolism - CORRECT ANSWER - endergonic; build larger molecules from smaller
ones
Catabolism - CORRECT ANSWER - exergonic; larger molecules are broken into smaller
ones
Homeostasis - CORRECT ANSWER - the body's ability to maintain relatively stable
internal conditions *function of human physiology!
Negative Feedback - CORRECT ANSWER - a mechanism of response in which a
stimulus initiates reactions that REDUCE the stimulus
Positive Feedback - CORRECT ANSWER - A physiological control mechanism in which
a change in some variable triggers mechanisms that amplify the change.
Signs - CORRECT ANSWER - objectively measurable
Symptoms - CORRECT ANSWER - only measured by the patient; feelings
, Molecule - CORRECT ANSWER - two or more atoms held together by covalent bonds
Solvency - CORRECT ANSWER - ability to dissolve matter
Cohesion - CORRECT ANSWER - (physics) the intermolecular force that holds together
the molecules in a solid or liquid
Adhesion - CORRECT ANSWER - an attraction between molecules of different
substances
Thermal Stability - CORRECT ANSWER - Refers to the temperature of waters ability to
remain stable.
Carbohydrates - CORRECT ANSWER - sugars and starches
Monosaccharides - CORRECT ANSWER - single sugar molecules; glucose, fructose,
galactose
Disaccharides - CORRECT ANSWER - Carbohydrates that are made up of two
monosaccharides
Lipids - CORRECT ANSWER - nonpolar molecules that are not soluble or mostly
insoluble in water
phospholipids - CORRECT ANSWER - A molecule that is a constituent of the inner
bilayer of biological membranes, having a polar, hydrophilic head and a nonpolar, hydrophobic
tail.
Proteins - CORRECT ANSWER - made up of amino acids joined by peptide bonds
