BMS 300 FINAL EXAM QUESTIONS AND
ANSWERS
Dipole Moment - ANSWER Partial negative and partial positive charge
What is responsible for surface tension? - ANSWER Hydrogen bonding
Hydrophilic - ANSWER "water loving"
Hydrophobic - ANSWER "water fearing"
Hydration Shell - ANSWER Water surrounding the ions
Diffusion - ANSWER The movement of ions from high to low concentrations
Osmosis - ANSWER Diffusion of water
Amphipathic - ANSWER "both loving"
Head group characteristics - ANS Hydrophilic, charged, phosphodiestor bonds
Tail characteristics- ANS Hydrophobic, uncharged, ester bonds.
,Characteristics of proteins - ANS Composed of amino acids, polypeptides,
enzyme, structural elements, and transmembrane proteins.
Characteristics of Transmembrane Proteins - ANSWER Has a lumen that is a
hydrophilic pathway, allows movement of ions, and has R-groups. Hydrophobic
interacts with lipid bilayer and hydrophilic interacts with pathway/lumen
Characteristics of prokaryotes - ANSWER Archea and bacteria. Single celled,
no membrane bound "organs", free floating DNA (circular)
Eukaryotes - ANSWER Fungus plants and animals. Multi-cell, organelles,
nucleus (DNA compacted)
What is in the nucleus? - ANSWER DNA
Nuclear pores - ANSWER Transport of molecules. It is selective to protein
and RNA
What is rough about the rough endoplasmic reticulum? - ANSWER
Ribosomes
What does glycosylation mean? - ANSWER It has sugars on it
Where does final processing occur? - ANSWER Golgi Apparatus
Ribosome - ANSWER Where proteins are made
, Rough Endoplasmic Reticulum - ANSWER Folding, glycosylating, and
packaging of proteins
Transmembrane proteins - ANSWER Cross the membrane and are on both the
inside and outside of the cell
Lysosomal proteins - ANSWER Destined for delivery to the lysosome
Secreted proteins - ANSWER Destined to leave the cell
To what is the smooth endoplasmic reticulum responsible? - ANSWER Fat
processing
Characteristics of the mitochondira - ANSWER It is ATP. Is double layered,
and is passed down from the mom only
What is the lysosome similar to? - ANSWER A garbage disposal
Characteristics of long transport - ANSWER Polymer: microtubules.
Monomer: tubulin. Motor protein (vesicle transporting ATPase): kinesin is
positive directed and dynein is negative directed
Characteristics of local transport - ANSWER Polymer: filamentous actin.
Monomer: globular actin. Motor protein (vesicle transporting ATPase): mysoin.
Central Dogma - ANSWER DNA ---replication---> DNA ---transcription--->
RNA ---translation---> protein
