holtadit:
Yeah... i see.


Thanks again man !  :)

saleemsamer:
would some1 plz care to explain the following from the bio syllabus:

- explain enzyme action in terms of the ‘lock
and key’ model

- outline the use of microorganisms and
fermenters to manufacture the antibiotic
penicillin and enzymes for use in biological
washing powders

- describe the role of the fungus Penicillium in
the production of antibiotic penicillin

1) each enzyme has its own substrate tht is complementary to its active site (like key and lock)
2)enzyme in washing powder:
a)protease use for protean stains and lipase for fat and greasy stains
b) put micro organism (bacteria or fungi) in fermenter with optimum conditions to reproduce (asexual):
1)temp.( by cold water or steam)
2)sugar --> energy
3)ammonia ---> nitrogen for protean
4)air
5)salt --> help metabolic reaction
6)light for algae i used


if u need the fungi it is filtered after this process (residue)
if u need the enzyme it will be in the filtrate
the penicillin is made from Penicillium

holtadit:
CnH2n+2(g) + (1.5n+0.5)O2(g) nCO2(g) + (n+1)H2O(g)


Thats the formula to balance the equation for the burning of an ALKANE

Whats the quick method for ALCOHOL and ALKENE
