Bio revision? Please, z.

Hey peepo.
Hectic day & I don't really care to elaborate.
After school was fun @ kfc w/ Aishah & Syuhadah.
Now, I'm going to proceed to Bio revision(which is like hopeless).
Don't read on le?




What are enzymes?
Enzymes are biological catalysts made of protein. They alter the rate of chemical reactions without themselves being chemically changed at the end of the reaction. ( reactions that build up/break down substances)

amylase - starch to maltose
maltase - maltose to glucose
proteases - proteins to amino acids
(I always forget this part, ccb!)

Characteristics
1. Enzymes speed up chemical reactions.
2. Enzymes are required in minute amts.
3. Enzymes are specific.
(lock & key hypothesis - I forget everything about this, manzxc! -.-)

Denaturation is the change in the three dimensional structure of an enzyme or any other soluble protein, caused by heat or chemicals such as acids or alkalis.
