duodenum is pH 7.6 – 8.6 1
P2 – Pencernaan protein berlaku di dalam perut tetapi di dalam
duodenum berlakunya pencernaan lipid, polipeptida dan 1
kanji.
The digestion of protein occurs in the stomach but in duodenum
the digestion of lipid, polypeptide and starch occur
P3 – Perut dalam keadaan berasid manakala duodenum dalam
keadaan beralkali.
The stomach has acidic condition whereas the duodenum has alkaline
condition
P4 – Asid hidroklorik dirembeskan ke dalam perut untuk
menyediakan keadaan berasid manakala hempedu
dirembeskan ke dalam duodenum untuk menyediakan keadaan
beralkali.
Hydrochloric acid is secreted into the stomach to prepare acidic
condition while bile is secreted into the duodenum to prepare
alkaline condition.
P5 – Di dalam perut, enzim pepsin dirembeskan manakala di
dalam duodenum, lipase, tripsin dan amilase pankreas
dirembeskan.

lipase, trypsin and pancreatic amylase are secreted

Pencernaan/ Digestion: 1
P1 – Pencernaan protein berlaku di dalam perut, duodenum dan
usus kecil 1

small intestine 1

P2 – Di dalam perut, pepsin menghidrolisiskan protein kepada
polipeptida
In the stomach, pepsin hydrolyses protein into polypeptides

P3 – Di dalam duodenum, tripsin menghidrolisiskan polipeptida
kepada peptida

P6 – Asid amino diserap melalui pengangkutan pasif ke dalam 1 5
kapilari darah dan dibawa ke hati (melalui vena portal hepar) 20
Amino acid absorbed by passive transport into blood capillary and
brought to the liver (through hepatic portal vein)

Asimilasi/ Assimilation: 1

protoplasma baharu dan membaiki tisu yang rosak. 1
In body cell, amino acids are used to synthesis new protoplasm 1
and also repair damaged tissues.
P8 – Asid amino digunakan untuk mensintesiskan hormon dan 1
enzim dalam sel-sel badan. 1
Amino acids are used to synthesis hormones and enzymes in body cells 1
P9 – Hati mensintesiskan plasma protein dan enzim daripada asid 1
amino. 1

P10 – Lebihan asid amino tidak dapat disimpan di dalam badan 1
dan dipecahkan melalui proses pendeaminaan untuk 1
membentuk urea dan disingkirkan.
Excess amino acids cannot be stored in the body and are broken down
through deamination process to form urea which is then expelled.
P11 – Apabila bekalan glukosa tidak mencukupi, hati akan
menukarkan asid amino kepada glukosa.
When the glucose supply is insufficient, the liver converts amino
acids into glucose.

amilase pankreas serta hormon insulin dan glukagon.
Pancreas cannot secrete trypsin, lipase and pancreatic amylase
enzymes and insulin and glucagon hormones
P2 – Ubah cara memasak daripada menggoreng kepada merebus
dan mengukus.
Change cooking style from frying to boiling and steaming
P3 – Kurangkan makanan yang berlemak seperti daging merah,
daging organ dan mayonis kerana kekurangan enzim lipase.

mayonnaise because of low lipase enzyme.
P4 – Kurangkan makanan berkarbohidrat seperti nasi, tepung
gandum dan pastri kerana kekurangan hormon insulin.
Reduce intake of carbohydrates such as rice, flour and pastry
because of low insulin hormone
