Flashcards in Bioenergetics Deck (14)
Synthesizes biomolecules from smaller units
Breaks down biomolecules in to smaller units
Gibbs free energy formula
If ∆G is negative...
Reaction will proceed forward, and will be exergonic
Is ∆G is +...
Reaction in unfavorable, and will be endergonic
Standard vs. biological standard ∆G
Standard is at 1 ATM and pH=0, biological is at pH=7
For the ∆Gº', what if eq is less than 1?
Reaction is endergonic and ∆Gº' is positive
For ∆Gº', what if Keq is greater than 1?
Reaction is exergonic, and ∆Gº' is negative
Why are carbohydrates more easily accessed than lipids?
Carbs are more oxidized
What chemical reaction is energy derived from (general)?
Oxidation of metabolic fuels
Parts of ATP synthase
F1 (inside membrane)
F0 (incorporated into the membrane)
Why is Mg2+ important to ATP?
Draws electron density from the Os and makes the Ps more negative, thus more easily attacked by H2o
Inhibits Mycobacterium ATP synthase (TB)
