feedback jinhibition j- jANS✓✓-reversiable, jnoncompetive jinhibition jof jan
jenzyme jin ja jpathway jby ja jproduct jof jthat jpathway
induced jfit j- jANS✓✓-substrate jbinding jcauses ja jconformational jchange
Which jtype jof jinhibition joccurs jwhen ja jparticular jdrug jbinds jto jthe jallosteric
jsite jof jan jenzyme jand jsubsequently jchanges jthe jenzymes jstructure? j- jANS✓
✓-noncompetive
competitive jinhibition j- jANS✓✓-A jmolecule jwhich jcompetes jwith jthe jsubstrate
jfor jbinding jto jthe jenzyme jactive jsite jthere jby jinhibiting jthe jenzyme's jactivity.
noncompetitive jinhibition j- jANS✓✓-A jmolecule jwhich jinhibits jthe jenzyme
jaction jby jbinding jat ja jsite jother jthan jthe jactive jbinding jsite jof jthe jenzyme.
Select jTrue jor jFalse: jthe jlower jthe jactivation jenergy jfor ja jreaction, jthe jfaster
jthe jreaction jrate. j- jANS✓✓-true
Specificity jmeans jthat jthey jwill jbind jto jone jspecific jmolecule jor jclass jof
jmolecules jand jusually jcatalyze jonly jone jtype jof jreaction. j- jANS✓✓-true
How jdo jenzymes jeliminate jthe jneed jfor jhigh jtemperatures jto jcomplete ja
jreaction? j- jANS✓✓-The jneed jfor jhigh jtemperatures jis jeliminated jby jlowering
