AS BIOLOGY P-33

[afoo.666]

s1 was sucrose. s2 was starch. s3 was glucose.
enzyme E do not hydrolise sucrose but starch.

 

[beeloooo]

S1= Non reducing sucrose
S2= starch
S3= reducing
Is this right?

spot on bro ! and starch hydrolysed !

 

[Sonysherpa]

spot on bro ! and starch hydrolysed !

Yeah me!! jk.. You have stat exam tomorrow?

 

[beeloooo]

yes

 

[aleezay]

H
ehe how did it go? Mine was good

it was okay.. Alhamdulillah

Is this right?

yup...!

 

[Bluejeans#]

yup...!

ppl saying sucrose wasn't dere in S1 -.- ?

 

[Sonysherpa]

ppl saying sucrose wasn't dere in S1 -.- ?

S1 had both
reducing and nonreducing sugar

 

[Sonysherpa]

S

yes

ame situation here i have physics p4 also. :'(

 

[falcon678]

ppl saying sucrose wasn't dere in S1 -.- ?

sucrose waz there...they must ve not proprly done the non reducing test.....

 

[Bluejeans#]

sucrose waz there...they must ve not proprly done the non reducing test.....

yea !

yess...for me and another girl we got S1 to have non of the given biological molecules. no starch no glucose no sucrose!! and Enzyme E Hydrolysied S1 !!! i think there were two types of solutions and it depends on your luck of which one you'll get....

 

[plantaholic]

S1 had both
reducing and nonreducing sugar

it couldn't possibly be so because the question said that a solution had any ONE molecule

two friends of mine had the same issue. their results weren't matching with the rest of us. so they asked the lab people to check their solutions and it turned out that there was a labelling mistake, and that any 1 solution was repeated, from what i understand.

Thank God, they agreed to write a statement for the two girls to explain the situation..

 

[Sonysherpa]

Does anyone have biology mcq according to chapters?

 

[Sonysherpa]

it couldn't possibly be so because the question said that a solution had any ONE molecule

The question said traces of any biological molecule could be seen in more than 1 solution.. As i remember

Q2

 

[tanixx]

did we have to mark L M etc in vascular bundle diagram?

 

[tanixx]

what was the ration of areas?

 

[abdul arham]

i got 48:20 and you ?????????????????????

what was the ration of areas?
