The Cell:
Plasma membrane- aka “fluid mosaic model”- lipid bilayer 2 parts: 1)
2)
Hydrophobic/ hydrophilic3 types of cell junctions: describe each/ example
1)
2)
3)
Interstitial fluidOrganelles: see pg. 70
Cell transport:
Passive:
1)

Exocytosis:
Endocytosis:
What is clathrin?
PhagocytosisPinocytosisWhy is it important to keep the Na and K ion gradient? Higher concentrations either in or out of the
cell? (pg 82)
Cell Adhesion Molecules- (CAMS) do what?
NucleusNuclear envelopeNucleoliChromatin- made up of… vs. a chromatid vs. chromosome
Stages of Life cycle:
Interphase:
1. G1

ProphaseMetaphaseAnaphaseTelophase- (cytokinase ends this phase)
Transcription:
RNA polymerase3 types of RNA molecules:
1) tRNA
2) mRNA
3) rRNA
How can 300,000 different proteins be made from only 26,000 genes? (Pg 106-107)
Translation:
Start codon?
What is needed for translation to take place?
Describe the process of translation. (pg. 108-109)
