No answer
Prostate
Alkaline phosphatase
Catalytic amplification to analyze small amounts of DNA
PCR
Coupled metabolic reactions
Unidirectional
Negative Gibbs free energy favors reaction from
Left to right
Raise the reactants to the
Free energy of activation
Collision
Kinetic theory
[S] is high
Zero order
[S] is mid
Mixed order
Reaction is proportional to reactants and products
Mixed order
Two factors always measured when dealing with enzymes
Km and Vmax
Affinity can be measured through
Km
Ability to maintain a constant internal environment despite changes in external environment
Homeostasis
Concentration remains constant over time
Constitutive enzyme
Enhances
Activator
Mean concentration of metabolic intermediates remain relatively constant over time
Dynamic steady state
Addition of phosphate group
Phosphorylation
Addition of nucleotides
Nucleotidylation
At high temperatures
Enzymes are proteins and therefore denature
Low molecular weight carrier of chemical group of enzymes
Coenzyme
Equilibrium is equal to 1
