BIO 210 - FINAL EXAM REVIEW
QUESTIONS AND ANSWERS 100%
CORRECT
Anatomy - ANSWER-the study of structure
Physiology - ANSWER-the study of function
Metabolism - ANSWER-all the chemical reactions that happen in our body cells
Catabolism - ANSWER-the breakdown of complex molecules into simpler ones.
Catabolic reaction
Anabolism - ANSWER-The building up of complex molecules from simpler ones
Levels of Structural Organization - ANSWER-Atom (chemical), Molecule (chemical),
Cell tissue, Organ, Organ System, Organism
Homeostasis - ANSWER-The maintenance of the internal environment regardless of
external conditions
Negative feedback mechanism - ANSWER-Most feedback mechanisms are this type -
regulating body temperature, blood pressure, blood glucose
Cranial Cavity - ANSWER-Brain and spinal cord
vertebral cavity - ANSWER-spinal cord
thoracic cavity - ANSWER-heart and lungs
PH - ANSWER-Acid base concentration - homeostasis of acid base balance is
regulated by chemicals called buffers
buffers - ANSWER-acccept hydrogen ions when PH is high and donates when the PH is
low
Carbohydrates - organic compound - ANSWER-fructose, glycogen
Protiens - organic compound - ANSWER-amino acids and enzymes
Lipids - organic compound - ANSWER-triglycerides, cholesterol
, Nucleic acids - organic compound - ANSWER-DNA, RNA
abdominopelvic cavity - ANSWER-stoach digestive organs
parietal membrane - ANSWER-lines cavity wall
visceral membrane - ANSWER-lines the organs surface
ATP - ANSWER-a form of energy used by all reactions in cells. Made in the
mitochondria
4 elements that make up 96% of the human body - ANSWER-Oxygen, hydrogen,
carbon and nitrogen
atomic number - ANSWER-number of protons. Always the same as the number of
electrons
Atomic mass - ANSWER-decimal number - number of protons and neutrons together - if
you subtract the protons you get the number of neutrons
ionic bonds - ANSWER-the transfer of one or more electrons
anion - ANSWER-negative charge - gains one electron
cation - ANSWER-positive charge - loses one electron
covalent bond - ANSWER-shared electrons
2 types of covalent bonds - ANSWER-Polar - unequal sharing of electrons
Nonpolar - equal sharing of electrons
DNA nitrogenous bases - ANSWER-Adenine, Guanine, Cytosine, Thymine (AGCT)
RNA nitrogenous bases - ANSWER-Adenine, Guanine, Cytosine, Uracil (AGSU)
Plasma Membrane - ANSWER-Phospholipid bilayer composed of hydrophilic
(phosphate) heads and hydrophobic (lipid) tails
Resting membrane potential - ANSWER-maintained by sodium potassium pump (active
transport) - takes 3 sodium out and 2 potassium in
K+ Potassium - ANSWER-10 times higher inside the cell - major intracellular cation
Na+ Sodium - ANSWER-10 times higher outside the cell - major extracellular cation
