Flashcards in Bioenergetics Deck (14):
1

Anabolic pathways

Endergonic
Consume energy
Synthesizes biomolecules from smaller units

2

Catabolic Pathways

Exergonic
Releases energy
Breaks down biomolecules in to smaller units

3

Gibbs free energy formula

∆G=∆H-T∆S

4

If ∆G is negative...

Reaction will proceed forward, and will be exergonic

5

Is ∆G is +...

Reaction in unfavorable, and will be endergonic

6

Standard vs. biological standard ∆G

Standard is at 1 ATM and pH=0, biological is at pH=7

7

For the ∆Gº', what if eq is less than 1?

Reaction is endergonic and ∆Gº' is positive

8

For ∆Gº', what if Keq is greater than 1?

Reaction is exergonic, and ∆Gº' is negative

9

Why are carbohydrates more easily accessed than lipids?

Carbs are more oxidized

10

What chemical reaction is energy derived from (general)?

Oxidation of metabolic fuels

11

Parts of ATP synthase

F1 (inside membrane)
F0 (incorporated into the membrane)

12

Why is Mg2+ important to ATP?

Draws electron density from the Os and makes the Ps more negative, thus more easily attacked by H2o

13

Bedaquiline

Inhibits Mycobacterium ATP synthase (TB)

14

Baz-423 therapy

Treatment for systemic lupus erythematosus
