Active h transport h - h CORRECT h ANSWER h -
movement h of h molecules h across h a h cell h membrane h from h a h region h of h lower
h concentration h to h a h region hof h higher h concentration—
against h the h concentration h gradient. h Active h transport h requires h cellular h energy h to h achieve
h this h moveme hnt.




Passive h transport h - h CORRECT h ANSWER h -
Requires h NO h energy, h movement h of h molecules h from h high h to h low h concentration, h moves
h with h the h conc hentration h gradient




Covalent h bond h - h CORRECT h ANSWER h -
A h chemical h bond h that h involves h sharing h a h pair h of h electrons h between h atoms h in h a
h molecule




Ionic h bond h - h CORRECT h ANSWER h -
Linkage hformed hfrom hthe helectrostatic hattraction hbetween hoppositely hcharged hions hin ha
hchemical hco hmpound. hSuch ha hbond hforms hwhen hthe hvalence h(outermost) helectrons hof hone
hatom hare htransferred hpermanently h to h another h atom.



Allosteric h bond h - h CORRECT h ANSWER h -
The h regulation h of h an h enzyme h by h binding h an h effector h molecule h at h a h site h other h than
h the h enzyme's h act hive h site.



Substrate h - h CORRECT h ANSWER h -reactant h of h an h enzyme-catalyzed h reaction



Substrate-enzyme h complex h - h CORRECT h ANSWER h -
The h substrate h connects h to h the h enzyme h to h perform h chemical h reactions. h It h connects h to
h the h enzyme h at hthe h active h site.

, Substrate h enzyme h inhibition h - h CORRECT h ANSWER h -
the h substrate h or h product h of h an h enzyme h reaction h inhibit h the h enzyme's h activity.
