And one more thing...first es complexes will form and then they will break...this will happen with tym

Yes they do form but if they don't reach 0 over time with enzyme having no pain in the *** is something quite strange

so it ultimately makes us choose option D.Nothing is wrong in they showing us the complex conc from the top to the bottom anyway if it makes sense right?

Bro it's not the logic reason tbh how could enzyme be denatured over time?

 

[innovative_1]

maybe if something happened to enzymes the graph would be like a,for e.g it denatures so conc would not reach 0

If u read question carefully other things r kept constant

 

[Hisham Khan]

Because of ph change due to H+ ions when complex change into product and medium gets too alkaline or too acidic.Enzyme can stop working because product act as uncompetitve inhibitor.You can't control that right?

Okay so what do u think of the INITIAL part of the graph? How could it be max at time zero?

 

[Hisham Khan]

Everything is constant and ok right,so Answer is D then what's the problem?

C'mon bro it never happens!! Don't make prediction be precise

It isin't necessary to start a graph from origin right?.They were studying how enzyme substrate complex changes over time,so it would make sense for the graph to start when all the enzyme is saturated with substrate molecules and enzyme substarte conc is max and see the changes happen to it overtime when time passes

 

[Hisham Khan]

C'mon bro it never happens!! Don't make prediction be precise

It does happen and anyways you answered your own question.
IF THE CONDITIONS ARE CONSTANT AND NO CHANGES OCCUR TO ENZYME,HOW DO YOU EXPECT ENZYME SUBSTRATE COMPLEX TO NOT CHANGE INTO PRODUCT FULLY.
Again you answered your own question.

Bro if u think concentration gets constant with time then it SHOULD BE LEVELED OFF

 

[Hisham Khan]

Bring it on

 

[Hisham Khan]

Bro if u think concentration gets constant with time then it SHOULD BE LEVELED OFF

Concentration doesen't get constant over time,it reaches 0 (Oval shaped 0) BECAUSE NO COMPLEX IS LEFT FOR ENZYME TO CHANGE INTO PRODUCT OVER TIME!

Come on!!!! see the graph carefully IT IS STARTING FROM THE ORIGIN

 

[A*****]

YES THIS IS TRUE THAT AFTER SOME TIME, THE CONCENTRATION SHOULD BE ZERO BUT YOU CAN NOT PROVE THAT IT IS NOT ZERO AT TIME ZERO

 

[innovative_1]

Guys stop wasting time we can't strict to one question time is short

 

[Hisham Khan]

THEY SAID A LITTLE IN EXCESS TO CONFUSE YOU BRO!
IT DOESENT MATTER LOL BECAUSE CONDITIONS ARE CONSTANT.
ANSWER MY QUESTION FIRST.HOW CAN A ENZYME NOT CONVERT EXCESS SUBSTRATE INTO PRODUCT OVER TIME IF NOTHING HAPPENS TO DISRUPT IT FUNCTION.
YOU ARE TELLING ME A ENZYME CANT CAHNGE EXCESS SUBSTRATE INTO PRODUCT EVEN IN A YEAR?

YOU TELLONG ME

 

[Hisham Khan]

YES THIS IS TRUE THAT AFTER SOME TIME, THE CONCENTRATION SHOULD BE ZERO BUT YOU CAN NOT PROVE THAT IT IS NOT ZERO AT TIME ZERO

IF YOU PLS LOOK VERYYYY CAREFULLY YOULL SEE THAT INDEED GRAPH STARTS FOM 0, I AGREE BUT I MEANT TO SAY IT CAN EVEN START FROM MAXIMUM WHEN ENZYME IS FULLY SATURATED?????.
IF YOU LOOK AT YOUR GRAPH A YOU CAN SEE THE CONC NEVER REACHES 0,SO EVEN THOUGH IT STARTS FROM 0 IT IS WRONG CAUSE IT DOES NOT REACH 0.HOPE YOU GET IT

 

[Hisham Khan]

I'm pissed cause I was doing chemistry ...

Cool down bro
