AvSa nodeCereblumVital functionsEpistasisFree practice exam:ANP- atrial natriuretic peptide -(heart failure) : released from the heart, causes natriuresis inthe kidneys ( flush Na and thus water out of body and reduce b.p.),**acts as a vasodilator**,deactivate reninRenin: activate the angiotensin II that induces secretion of ADH and aldosterone , reabsorbswater , increase b.p.,**acts as a vasoconstrictor**Epinephrine and norepinephrine increase b.p, **acts as a vasoconstrictor**Nicotine: "same as epinephrine and norepinephrineand reninBNP-Brain natriuretic peptide-(heart failure):released from the heart, activate ANP , workssame as ANP but has longer half life.BNP/ANP works opposite to Renin
--Intracellular binding steroidal hormones are slow acting cause theyupregulate genes whichmust be transcribed and translated--Desmosomes aid in cell-cell adhesion--microfilaments of the cytoskeleton are made up of actinThe plasma membrane is composed of a phospholipid bilayer--Viruses :-Have capsid ( made of capsomere proteins) that form a protective coat around the virus-A virus that infects bacteria is known as a bacteriophage-Viruses can have DNA as their genetic material or RNA as their genetic material-Viruses don't have cell membrane or nucleus-/ they don't have membrane-boundorganelles.FYI sites:--Photosynthesis:C3 plants (live where water is available; ex.Rice & wheat):O2 and CO2are available, so RUBPbinds to CO2(good for energy)or O2(photorespiration occurs, thus wastes energy)C4 & CAM plants (live in hot/dry areas; ex.corn and sugar cane ->C4.cacti (@ desert)->CAM): CO2is available, so RUBP binds to CO2(good for energy)C4 & CAM 've same mechanism , but CAM open stomata [email protected]RUBP bind to CO2 or O2
CO2->glucose(efficient)O2->CO2(waste energy)--Molecular cloning1.insert(DNA fragment from living cell)2.vector(circular DNA that can be amplified in E. coli3.Restriction enzymes: cleave double stranded DNA and produce single strd. nucleotide tails4.DNA ligase: it brings the tails of insert & vector together when combined making one DNAmolecule5.E.coli cell: help in making multiple DNAs via transformation process6.DNAis iced and then temp. is up to 420C to drive some of the DNA inside the E.coli cells, inwhich when adding antibiotic those **target gene vectors will have antibiotic resistance**,thus growSource:--A low cell surface area to volume ratio would stimulate a cell to divide--terminator sequenceare the certain sequences on the DNA which ends the process oftranscription(the synthesis ofmRNA which is transcribed).
