week 2 Flashcards
1
Q
How cells lower deltaG?
A
Coupling reactions
2
Q
Rate-limiting?
A
Irreversible steps. Can occur through negative feedback, halting the process.
3
Q
Ideal concentration
A
At half maximum value (allows for maximum regulation)
4
Q
Upper Glycolysis (3 steps)
A
Two ATP invested
Traps/Activates glucose (phosphate added to prevent it from leaving the cell)
Glucove cleaved in half
5
Q
Lower Glycolysis (2 steps)
A
Oxidation and phosphorylation
2 ATP forming reactions
6
Q
Oxidative Phosphorylation
A
In mitochondria
7
Q
Electron transport chain (3 points)
A
NADH –> NAD+
FADH2 –> FAD
2H+ + 2O2 –> H2O
pumps electrons out, gives energy for ATP synthase
8
Q
Mass Action kinetics
A
Reaction rate proportion to product of concentration of reacting species
9
Q
Steady state
A
Rate of change in 0
