SI WS5 Flashcards
activation energy
the energy that must be invested to initiate a rxn
enzymes
are catalytic proteins
- they speed up exergonic rxns
lowers activation energy
5 types of enzymes
- normal
- allosteric activator
- allosteric inhibitor
- non competitive inhibitor
- competitive inhibitor
substrates bind to …
bind to enzymes at the active site
Allosteric activator
when binding to a regulatory site to activate enzyme
Allosteric inhibitor
binds to regulatory site and changes shape of enzyme so substrate cant attach
non-competitive inhibitor
after substrate has binded it prevents the substrate from being turned into product
competitive inhibitor
binds to active site which blocks substrate
oxidation
loses electrons and/or hydrogen
reducing agent
donates an electron
oxidizing agent
what gets reduced,
gain electrons
reducing agent
what is oxidized
donate electrons
substrate level phosphorylation
ADP to ATP
- gain ATP
how is pyruvate moved into mitochondrial matrix?
oxidative decarboxylation and transported by a carrier protein
