Introduction To Metabolism Flashcards
1
Q
Location of glycolysis, beta oxidation, TCA and oxidative phosphorylation
A
Glycolysis: cyto
Beta oxidation: matrix
TCA: matrix
Oxidative phosphorylation: inner mitochondrial membrane
2
Q
ATP structure
A
Adenosine -> ribose-> ester bind -> triphosohate
3
Q
ATP uses
A
Muscle Contraction
Na/k atpase
Phosphorylates metabolic intermediates
4
Q
How’re enzyme reactions regulated
A
[Substate]
[enzyme]
Inactive-> active enzymes
Allosteric control
5
Q
How’re enzymes phosphorylated and dephosphorylated? What does phosphorylation do
A
Phosphorylated by protein kinase
Dephosphorylated by protein phosphatase
Phosphorylation activates it
6
Q
Types of cofactors
A
Ions
Conenzymes
7
Q
What does ctp utp and gtp do
A
Ctp: lipids
Gtp: proteins
Utp: complex sugars
