LKS Enzim


LEMBAR KERJA SISWA  ( inquiry)
ENZIM  
JUDUL : FAKTOR YANG MEMPENGARUHI KERJA ENZIM
TUJUAN : MENGETAHUI FAKTOR-FAKTOR YANG MEMPENGARUHI KERJA ENZIM
MATERI  : kerja enzim di pengaruhi oleh beberapa faktor yaitu Ph, suhu, jumlah subtrat,
Dalam hati banyak terdapat  enzim katalase yang mengubah hidogen peroksida menjadi oksigen dan uap air . Hydrogen peroksida perlu diurai menjadi air dan oksigen karena  bersifat racun bagi tubuh .
Alat dan bahan :
Hati ayam, HCl 10 %, NaOH10%,H2O2, korek api, termometer, bunsen ,
Cara kerja :
Lakukan percobaan untuk menemukan 1 faktor yang mempengaruhi kerja enzim ,
Untuk membantu kalian , lakukan sesuai tuntunan kerja dibawah ini !
