Cards

Term
Michaelis-Menton equation
Definition
Vo=Vmax[S]/Km+[S]
Term
Competitive inhibition
Definition
I binds only to E, not ES (I and S compete for same binding spot)
Term
Do competitive inhibitors affect the apparent Km (X axis)
Definition
Yes, increases it (causing a slower rxn)
Term
Do competitive inhibitors affect the Vmax (Y axis)
Definition
No
Term
Non-competitive inhibition
Definition
I binds to E and ES (S and I not competing for the same spot)
Term
Does noncompetitive inhibition affect the Km?
Definition
no
Term
Does noncompetitive inhibition affect the Vmax?
Definition
yes, decreases it
Term
Uncompetitive inhibition
Definition
I binds to ES
Term
Does uncompetitive inhibition affect the Km?
Definition
Yes, increases it (causing a slower rxn)
Term
Does uncompetitive inhibition affect the Vmax?
Definition
yes, decreases it
Term
-conic acid
Definition
-COOH
Term
-uronic acid
Definition
C6 oxidized to a carboxyl group (-COOH)
Term
Glucose is epimer with 2 things
Definition
Galactose (C4) and mannose (C2) {Little man}
Term
Glucose is isomer with one thing
Definition
Fructose
Term
Alpha anomeric carbon OH is pointing which way?
Definition
Down
Term
Beta anomeric carbon OH is pointing which way?
Definition
Up
Term
Structure of cellulose
Definition
Linear with Beta bonds
Term
structure of glycogen
Definition
branched with alpha 1-4 ande alpha 1-6 links
Term
Enzymes unique to gluconeogenesis from glycolysis
Definition
Pyruvate carboxylase , PEP Carboxykinase, Fructose-1,6- bisphosphatase, Glucose-6-phosphatase {Pathway Produces Fresh Glucose}
Term
G-6-P Dehydrogenase
Definition
first step in PPP, uses G-6-P as substrate
Term
Out of tryptophan, phenylalanine, and tyrosine, how do they rank for UV 280 absorption
Definition
tryptophan> tyrosine> phenylalanine
