Intro to metabolism
Definitions
-
-
-
Entropy
is a measure of molecular disorder, or randomness
-
-
equilibrium
The point at which forward and reverse reactions occur at the same rate, describes a state of maximum stability
Phosphorylation
transfer of a phosphate group from ATP to another molecule, is typically used to power endergonic reactions
The recipient molecule, a phosphorylated intermediate, is more reactive that the original molecule
inhibitors
competitive inhibitors
closely resemble the substrate, and can bind to the enzyme’s active site
-
-
allosteric regulation occurs when a regulatory molecule binds to a protein at one site and affects the protein’s function at another site
In cooperativity, substrate binding to one active site triggers a shape change in the enzyme that stabilizes the active form for all other sites
Cofactors are nonprotein helpers that bind to the enzyme permanently, or reversibly with the substrate
Energy
-
-
The capacity to cause change, can be used to do work—move matter against opposing forces
-
-
Thermodynamics
-
-
-
Laws:
- The energy of the universe is constant
- Every energy transfer or transformation increases the entropy of the universe
