Myoglobin correct answers monomeric protein with single heme molecule in muscle cells no cooperation always has higher oxygen affinity than hemoglobin - selfish pulls oxygen from hemoglobin regardless of PO2 Hemocyanins correct answers blue when oxygenated copper containing non-porphyrin rings multiple oxygen binding sites (up to 160) every copper binds one oxygen pigments free floating in hemolymph chlorocruorins correct answers modified porphyrin ring with iron binding oxygen ...

which class of biomolecules includes both linear and branched polymers correct answers carbohydrates what percentage of the amino acids have a chiral alpha carbon correct answers 95% if in a weak acid solution where there is a 100-fold excess of the conjugate base (A-) versus the acid form (HA) then the pH is: correct answers two units above the pKa - 100/1 in a sequence of amino acids, which side is the N terminus side correct answers the side that is listed first (read left to right) ...

How are heme and non-heme iron differentHeme-Fe is contained in a protoporphyrin ring -found in meat in hemoglobin, myoglobin, cytochromes -highly bioavailable Non-Heme-can be organic chelates (ferric, citrate, ferrous fumarate) -can be constituents of biological molecules (e.g iron sulfur enzymes, ferritin) -found in plants and meat -relatively poorly bioavailable ferrous iron vs ferric ironFerrous iron (Fe2+) is better absorbed than ferric iron (Fe3+) Vitamin C enhances absorption by...

Biology 353 Exam 3 Practice Latest Questions And Answers the partial pressure of carbon dioxide in alveolar air after inspiration of fresh dry air is lower than one would expect because ANS water vapor contributes to the overall alveolar gas pressure the pulmonary and systemic circulation have similar ANS blood flow per minute and diastolic pressures Myoglobin is an oxygen binding pigment found in some muscles. It has a higher oxygen affinity than hemoglobin. Therefore, it ANS facilita...

What is hemoglobin composed of? 4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? Porphyria Porphyria Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? Methemoglobin is a form of hemoglobin that contains ferric [Fe3+] iron and h...
