1
Q

Anabolic pathways

A

Endergonic
Consume energy
Synthesizes biomolecules from smaller units

2
Q

Catabolic Pathways

A

Exergonic
Releases energy
Breaks down biomolecules in to smaller units

3
Q

Gibbs free energy formula

A

∆G=∆H-T∆S

4
Q

If ∆G is negative…

A

Reaction will proceed forward, and will be exergonic

5
Q

Is ∆G is +…

A

Reaction in unfavorable, and will be endergonic

6
Q

Standard vs. biological standard ∆G

A

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

7
Q

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

A

Reaction is endergonic and ∆Gº’ is positive

8
Q

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

A

Reaction is exergonic, and ∆Gº’ is negative

9
Q

Why are carbohydrates more easily accessed than lipids?

A

Carbs are more oxidized

10
Q

What chemical reaction is energy derived from (general)?

A

Oxidation of metabolic fuels

11
Q

Parts of ATP synthase

A

F1 (inside membrane)

F0 (incorporated into the membrane)

12
Q

Why is Mg2+ important to ATP?

A

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

13
Q

Bedaquiline

A

Inhibits Mycobacterium ATP synthase (TB)

14
Q

Baz-423 therapy

A

Treatment for systemic lupus erythematosus
