LG

primary role of ATP is to convert a bad __ into a good phosphate-based __

thermodynamics

ATP improves the reaction ________ (product yield) because LG's are part of the products

weakening

creating a better LG is linked to ______ a bond

energy

weakening a bond requires _____

resonance

ADP is a good LG because the negative charge is spread out by ________

thiol

______-based LG's are used for formation of oxyester bonds

bigger

R2-S^- is a better LG than R2-O^- because it's _____

orbital

SCoA cannot delocalize electrons with a carbonyl, due to poor _____ overlap between large S atom and smaller C atom

are not

thioesters and thiol LG's ____ (are / are not) required for ester bond formation

degrade

glutaminase is used to _____ glutamine

ATP

cells used an ____-based mechanism that avoids water as a product

44.8

imaginary hydrolysis of 1 mole of ATP supplies __ kJ

Keq

if you have too low ___, then concentrations may be too high or low for cell functions

ATP

___ experiences more internal charge repulsions than ADP

resonance

bonding in ADP is better stabilized by ________ than bonding in ATP

HEI

___ are molecules whose imaginary hydrolysis is visualized as the energy-producing components in real rxns or a step in a real rxn

HEI

two characteristics of ___ 1) Energy from hydrolysis is = or > than hydrolysis of ATP 2) Cells do not synthesize them for final product

HEI

two kinds of ___ 1) Enzyme active site bound 2) Free in the cell

stronger

the reason Keq for HEI hydrolysis rxns is because the bonding in the hydrolysis products is _____ than bonding in reactants

HEI

examples of ___'s 1) Acyl phosphate (Glutamyl phosphate) 2) Thioester (Acetyl CoA) 3) Nucleotide Sugar
