|
The theory that the shape of the enzyme and the substrate are altered upon binding
|
induced fit
|
|
|
|
_________ inhibitors compete with the substrate by binding reversibly with noncovalent bonds to the active site. Km increases, No change in Vmax
|
Competitive
|
|
|
|
__inhibitors bind at a site other than the active site and cannot be overcome by excess substrate and lower Vmax. Km remains same
|
Noncompetitive
|
|
|
|
Regulation of enzymes occurs by ___, ____, ____ and ______.
|
proteolytic cleavage
reversible covalent modification control proteins allosteric interactions |
|
|
|
When a product downstream in a rxn comes back and inhibits the enzymatic activity in an early rxn
|
Negative feedback or feedback inhibition
|
|
|
|
Where the product returns to activate the enzyme
|
Positive feedback
|
|
|
|
These properly orient reactants and lower the activation energy
|
enzymes
|
|
|
|
molecular synthesis
|
anabolism

|
|
|
|
This takes place when a cell cannot use energy from NADH and pyruvate or has no oxygen
|
Fermentation
|
|
|
|
T or F: Fermentation recycles NADH back to NAD+
|
T
|
|
|
|
What is produced with each turn of the Krebs cycle?
|
1ATP 3NADH 1FADH2
|
|
|
|
a series of proteins including cytochromes with heme in the inner membrane of mitochondrion
|
electron transport chain
|
|
|
|
Aerobic respiration produces _ ATPs

T or F: Oxidative phosphorylation occurs along the ETC
|
true
|
|
|
|
Krebs cycle occurs in the _______
|
mitochondrial matrix
|
|
|
|
T or F: Then energy from the oxidation of NADH establishes a proton gradient between the inner membrane space and the matrix
|
T
|
|
|
|
T or F: Glycolysis occurs under anaerobic and aerobic conditions
|
T
