Soalan 16
Produk tenusu adalah sumber yang kaya dengan kalsium dan vitamin D. Kandungan kalsium
yang dibenarkan dan dicadangkan di dalam diet (RDA) adalah dari 700 miligram/ hari bagi
setiap kanak-kanak, 1,000 miligram/ hari untuk orang dewasa dan 1,200 miligram/hari untuk
wanita berumur 51 tahun keatas. Bagi wanita yang hamil dan menyusukan anak, pengambilan
kalsium yang dicadangkan oleh RDA ialah sebanyak 1,300 miligram. RDA untuk vitamin D bagi
kanak-kanak dan dewasa adalah di antara 600 dan 800 unit antarabangsa/hari. Produk tenusu
juga mengandungi laktosa. Produk-produk tenusu yang mengandungi laktosa yang tinggi
adalah susu, aiskrim dan keju. Laktosa juga ditambah di dalam makanan yang tertentu seperti
roti, bijirin, kuah salad, gula-gula dan makanan ringan. Makanan yang mengandungi wei,
hasilan sampingan susu, susu kering dan susu kering tanpa lemak juga mengandungi laktosa.
Berdasarkan maklumat ini, ibu Albert cuba untuk memaksa beliau mengambil segelas susu
kerana ia adalah baik untuk tumbesarannya. Rajah 2 pula menunjukkan keadaan Albert selepas
2 jam pengambilan susu. Setiap kali dia minum susu, keadaan yang sama akan berlaku.
Dairy products are an excellent source of calcium and vitamin D. The recommended dietary
allowance for calcium ranges from 700 milligrams per day in very young children to 1,000
milligrams for most adults and 1,200 milligrams per day in women aged 51 and older.
Pregnancy or lactation recommendations increase, with an RDA of 1,300 milligrams of calcium.
The RDA for vitamin D for children and adults ranges between 600 and 800 international units
per day. Dairy products also contain lactose.The most common dairy products that are high in
lactose include such as milk, ice cream, and cheese. Lactose is also added to some foods, such
as bread and baked goods, cereals, salad dressings, candies, and snacks. Foods that contain
whey, curds, milk by-products, dry milk solids, and nonfat dry milk also contain lactose.
Based on this information, Albert’s mother tried to force him to consume a glass of milk because
it is good for his growth. Diagram 2 shows the condition of Albert after 2 hours drinking the milk.
Every time he drinks the milk, the same condition will occur.

(a) The salivary glands produce saliva, which keeps the mouth and other parts of the
digestive system moist. It also helps break down carbohydrates (with salivary amylase,
formerly known as ptyalin) and lubricates the passage of food down from the oro-pharynx
to the esophagus to the stomach. There are three main pairs of salivary glands: the
parotid, the submandibular and the sublingual glands.
Kelenjar air liur menghasilkan air liur yang mengekalkan mulut dan bahagian lain di
dalam system pencernaan berada di dalam keadaan lembap. Ia juga membantu dalam
menguraikan karbohidrat (dengan amilase air liur yang sebelum ini dikenali sebagai
ptialin) dan pelincir untuk pergerakan makanan turun dari oro-farink ke esophagus
hingga ke perut. Terdapat tiga pasang kelenjar air liur iaitu kelejar parotid, kelenjar
submandibular dan kelenjar sublingual.

Permukaan dalam kelenjar air liur terdapat lapisan tisu epitelium yang menghasilkan
enzim amylase. Setiap hari Albert makan dua keping roti.Bagaimanakah sel-sel ini
menghasilkan enzim dengan dibantu oleh organel tertentu?
The inner surface of salivary gland has the presence of epithelial tissues which produce
the amylase enzyme. Every morning Albert eats two pieces of bread. How do these cells
produce the enzyme with the help of particular organelles?

4. Extracellular enzymes produce by ribosomes base on
RNA codes which attached to the rough endoplasmic
reticulum (ER)
