CYCLIC AMP lipidos ya lo vi

Question Answer
bindin glucagon /epinefrine to its receptor activates adenylate clyclase
synthesis of fatty acid occur incytosol
break down of fatty acid occure enmitochondria
the most important step in fatty acid syntheisfirs one , acetyl CoA ATP AND BICARBONATE form MALONy CoA
Coenzyme AFatty acid catabolism and synthesis
sources of acetyl COA for fatty acid synthiesispyruvate , glucose , citrate
allosteric enzyme that reguated the fatty acid synthesisAcetyl COA Carboxylase
HMG COA synthaserate limiting step in synthesis of ketone bodies in liver
HMG COA reductasakey regulatory enzyme in cholesterol biosynthesis
lecithin , cerebroside , cariolipinphospholipid derived from glycerol
sphingomyelin yield or secretasphingosine , choline
Niemann pick diseaseaccumulation of Sphingomyelin in CNS
micellestiny emulsified bile salts that absorb fatty acids
bile salts action or funtionabsortion of fatty acids 2 detergen action decreases surface tension allow intetinal tract to break fat
glycocholate and taurocholatenecesary for absortion of fatty acid
glycine /taurine = bile acid
memorize

Gluconeogenesis

 

Question Answer
gluconeogenesis is the process ofsynthesizin glucose
pyruvic acidis the starting point of gluconeogenesis
similar but not the exact reverseglycolisis
ocurs mainly inliver
begins in themitochondira
es al reves que el glycolytic pathwayF16B -ppfkinasa-F6P-ppgisomerasa -G6P ----- FINAL GLUCOSE
memorize

pentos phosphate path way

Question Answer
PPPno ATP is consume or produced
ATP is produced en humans viaelectorn transport / oxidative phosphorylation , sustrate lever phosphorylation
mayor role isproduction of NADPH for reductive biosynthesi ejmplo en fatty acidos
occure en elcytosol
it is control byinhibition of glucose 6 phosphate Dehydrogenase by NADPH es controlada por la innibicion d G6PD NAPDH
glucose 6 phosphate dehydogenases convert acetoacetyl CoA into acetyl CoA
memorize

glicolisis

Question Answer
phosphosfructokinasepace setting enzyme
hexokinasefirs step to use energy rather that produced
aldolaseproduce two distinct carbon base molecules
where in the organism occurs glycolisiscytoplasma
end of glicolisis yield2 pyruvic acid , net gain 2 ATP adn 2 NADH per glucose
Enzyme resposible for glycogen degradationphosphorylase
enzyme resposible for glycogen synthesisglycogen synthase
memorize

ETC eletron trasport chain OR respiratory chain

Question Answer
NADH FORM3 ATP
FADH FORM2 ATP
electron carrier complex 1NADH
electron carrier complex 2SUCCINATE DEHYDROGENASE
electron carrier complex 3ubiquinone oxidoreductase
electron carrier complex 4cytocrom xidases complex
memorize

TCA krebs cycle or citric acid clycle

Question Answer
the cycle star with4C Oxalaacetate + 2Acety coa - 2 Co2 and regenerted 4C compound of Oxalaacetate.
the pyruvate come fromglicolysis
most importan regulatory enzyme of the cycle iscitrate synthase , socitrate dehydrogenase , and a-ketoglutarate dehydrogenase complex
interconcetival enzyme in the cycleaspartic acid and oxaloacetic acid.
when those de cycle beginacety COA
Citric acid cycle compounds mnemonic"Can I Keep Selling Sex For Money, Officer? Citrate Isocitrate alpha Ketogluterate Succinyl CoA Succinate Fumerate Malate Oxaloacetate
memorize

PYRUVATE CAN BECOME WHAT AFTER IT COME OUT OF GLYCOLISIS. IN WHAT TISSUE OR ORGAN

Question Answer
conversion to lactateLDH dehidrogenase red blood cells lent cornea eye medulla of kidney testes and leukocytes
conversion to Acetyl-CoApyruvate dehydrogenase TCA or fatty acid synthesis
conversion to oxalaacetatepyruvate carboxylase liver and kidney not in the mucle
conversion to ethanolin yeast HONGOS no humans
memorize

embden - meyerhof pathway ( oral bacteria used this path way) PRODUCE 2 ATP

Question Answer
pyruvat is reduce tolactic acid via fermentation
cariogenic bacteria producelactic acid
bacteria that used this pathway areanaerobic and facultative anaerobic
aerobic bacteria used what pathwayEntner–Doudoroff produces one ATP
bacteria of the Embden-Meyerhof pathway lack of what key enzymesaldose and 6PPFK phosphofructokinases
memorize

PH

Question Answer
most importan extracellular buffer iscarbonic acid weak acid and H carbonates
3 proceses that body use to reguled ph pka removal of bicarbonate HCO3 in urine ,2 removal of CO2 in blood by the lungs 3 CABONIC ACID
determent of blood phbalanc between bicarbonata and CO2
mayor intracellular bufferHemoglobin
