Pentose
Colorless
Urobilinogen
Ig is kappa or lambda, never mixed:
True
5 phosphoryl group esterify 2nd hydroxyl group
Phosphodiester
Phosphoryl group linked to the phosphoryl group of a mononucleotide
Acid anhydride bond
From the mitochondria, outer membrane receptor
TOM 20./22
Proteins are transferred to this neighboring import channel
TOM 40
Repository of heme
RBC
Important element in body cause seen in hemoprotein
Iron
From apical surface to interior
DMT1
Ferric to ferrous
Ferrireductase
Bidirectional movement along nucleus and cytoplasm
Ran protein
True about signal peptide
At least 1 positive charge etc
Primary immune response
IgM
Nucleoside
Guanosine
Main antibody in secondary response. Opsomizes bacteria
IgG
Found on surfaces of B cells as a receptor for antigen
IgD
Function of Ig other than direct binding of antigen
Fc
Physiologic functions of nucleotides except
Energy metabolism
True of bilirubin except
Bound to albumin thru non covalent forces increases plasma solubility
Hydrostatic pressure of arterioles
37 mmHg (Book) 40 mmHg (ppt)
Involved in intra-GA transport & retrograde transport from the GA to the ER
COP I
Involved in export from the ER to either ERGIC or the GA
COP II
Transport in post-GA locations including the PM, TGN and endosomes
Clathrin
Regulated secretion from organs such as the pancreas
Secretory vesicles
Carry proteins to the PM & are also involved in constitutive secretion
Vesicles from the TGN to the PM
Low PO2 in peripheral tissues causes synthesis of:
2,3 - BPG
Direct measurement of CO
Heme oxygenase
Colourless compound
Urobilinogen
Colored compound found in feces
Stercobilin
Porphyrin ring
Hydrophobic
Blue-green color
Biliverdin
What happens to albumin when removed from bilirubin
Remains in plasma
Location of heme oxygenase
Endoplasmic reticulum
Conjugation of bile is catalyzed by
UDP-Glucoronyl transferase
Has large capacity that even under the pathologic conditions, transport does not appear to be rate-limiting for metabolism of bilirubin
Facilitated transport system
Derivatives of purine and pyrimidine that has a sugar-linked to a ring N
Nucleosides
Sugar is linked to a heterocyclic base via
B.N-glycosidic bond
True of a sugar that is linked to heterocyclic base
Pyrimidine at N1 ; purine at N9
Nucleoside with a phosphoryl group esterified to OH group of sugar
Mononucleotide
Free nucleotides
Xanthine
Hypoxanthine
Uric acid
Function of purines and pyrimidines
High group transfer potential
Nucleoside derivative of guanine
Guanosine
True about P50 except:
PO2 half saturates myoglobin
