76 - an enzyme that transfers phosphoryl groups between ATP and a metabolite ?
a- kinase
b- aldolase
c- enolase
d- mutase
answer is a .
--------------------------------------------------------------------------------
77 - the ion essential for kinase activity ?
answer - magnesium .
-----------------------------------------------------------------------------------
78 - the enzyme which catalyses the transfer of a functional group from one position to other ?
a- mutase
b- enolase
c- aldolase
d- kinase
answer is a . mutase . phosphoglycero mutase converts the 3 phosphoglycerate to 2 phosphoglycerate .
----------------------------------------------------------------------------
79 - compounds with high phosphoryl group transfer potentials are formed during glycolysis .
the above statement is true .
----------------------------------------------------------------------------------
80 - when the need for ribose 5 phosphate exceeds that of NADPH , reversal of the transaldolase and transketolase reactions , diverts ribose 5 phosphate from the glycolytic pathway .
the above statement is true .
---------------------------------------------------------------------------------
81 - after phosphorylation , galactose reacts with the UDPG to form glucose 1 phosphate and ___________ before an epimerization reaction ?
answer is UDP - GALACTOSE
------------------------------------------------------------------------------
82 - fructose metabolism in muscle requires only one step before it can enter into glycolysis ?
the above statement is true .
-----------------------------------------------------------------------------
83 - it has been demonstrated that triose phosphate isomerase has a reaction rate that is diffusion controlled and is therefore an example an enzyme that has reached catalytic perfection ?
the above statement is true .
------------------------------------------------------------------------------
84 - enolase catalyses a reaction that results in the formation of a high energy intermediate .
the above statement is true . the enzyme enolase catalyses the conversion of the 2 - phosphoglycerate to phosphoenolpyruvate .
------------------------------------------------------------------------------
85 - the statement which describes glycolysis stage II , the stage of energy recovery are ?
answer is --- two molecules of glyceraldehyde 3 phosphate are converted to pyruvate and four molecules of ATP are generated .
-------------------------------------------------------------------------------------
86 - ribulose 5 phosphate is converted to xylulose 5 phosphate by the action of the enzyme ?
a- isomerase
b- epimerase
c- kinase
d- aldolase
answer is b .
