Class 2 E1 Flashcards
standard state
about room temp
ΔG of rxn relies on ΔG 0 (free E at standard state cond’s)
RT and [products] and [substrates (reactants)]
standard state
For free E at standard state the higher [product] means?
more E is req’d.
For free E at standard state the larger your denominator the?
easier it is to move forward.
For free E at standard state the larger your denominator
the less E req’d.
ΔG
change in Gibbs free E.
ΔG naught
change in Gibbs free E of standard state.
ATP has a large
ΔG
ATP hydrolysis is a rxn used to?
drive other rxns forward
ADP is more stable than?
ATP
You phosphorylate what to make ATP?
ADP
Cells make their own ATP via?
ATP synthase
ATP hydrolysis has what type of ΔG?
positive
ATP is also
a nucleotide in RNA, can be incorporated into a long strand of mRNA.
Equilibrium
chemical state when forward rate equals reverse rate.
At equilibrium the net change of reactants and products is?
zero
Le Chatelier’s Principle states that
all rxns move toward equilibrium.
Equilibrium: the [reactants and products]
don’t need to be the same.
Equilibrium: more product =
rxn in reverse direction.
Equilibrium: more reactants / products =
rxn in forward direction.
Rxns are most favorable when?
they are at equilibrium.
Steady State
arrows same length in both directions.
If a rxn arrow is longer then
that direction is more favorable.
If a rxn arrow is shorter then
that direction is less favorable.
