Bagamana pencernaan protein terjadi pada manusia, apa fungsi getah lambung

Pencernaan protein dimulai pada saat makanan sampai dilambung, lambung menghasilkan enzim renin yang berfungsi menggumpalkan kasein yaitu protein susu. lambung juga menghasilkan  enzim peptin, pada saat dihasilkan peptin masih berupa pepsinogen yang akan berubah menjadi pepsin dengan bantuan HCL. Enzim pepsin berfungsi mengubah protein menjadi pepton. Pepton akan bergerak ke usus 12 jari disini terjadi pencernaan lebih lanjut dengan memakai enzim Tripsin yang dihasilkan pankreas. Tripsin berfungsi mengubah pepton menjadi asam amino. Asam amino siap diserap oleh oleh tubuh dan dipakai untuk oksidasi biologi sehingga dihasilkan energi.

Getah lambung berisi air, HCL, Pepsin dan renin. Secara umum berfungsi untuk mencerna makanan. secara rinci dapat dibaca pada penjelasan diatas.

Once upon a time, there was a Mouse, who always lived on the land. By an unlucky chance, he formed an intimate acquaintance with a Frog, who lived in the water.

            One day, the Frog was intent on mischief. He tied the foot of the Mouse tightly to his own. Then, the Frog led his friend, the Mouse, to the meadow where they usually searched for the food. After this, he gradually led him towards the pond in which he lived, until reaching the banks of the water. He suddenly jumped in, dragging the Mouse with him.

            The frog enjoyed the water amazingly and swam croaking about, as if he had done a good deed. The unhappy Mouse was soon sputtered and drowned in the water. Soon afterwards, his poor dead floated on the surface.

            A Hawk observed the floating Mouse from the sky. He dove down and grabbed it with his talons, carrying it back to his nest. The Frog, being still fastened to the leg of the Mouse, was also carried off a prisoner, and was eaten by the Hawk.

Pertanyaannya adalah:

My friends and I have just returned from an interesting and amusing holiday at Maninjau Lake, near Padang. The lake was a crater surrounded by dense forests and rice fields. We swam in the lake, ate fish from the lake, and enjoyed the cool breeze.

            From there we had a two hour trip to Bukittinggi, a small hill top town, which was clean, cool, and friendly. Day trips around the hill took us to some spectacular countryside with coffee, clove, and cinnamon farms. The traditional Minangkabau houses, with the roof shaped like a buffalo’s horns, are everywhere.

            On the following day, we went by plane to Medan and then a bus journey to Bukit Lawang, home of the WWF Orang Utan Rehabilitation Center. We stayed in the jungle in a very charming “hotel” with no running water and electricity. We took a bath in the river and had dinner under a kerosene lamp. But, it was quite a wonderful sight to see these giant creatures that came swinging along on trees. The surrounding jungle was alive with monkeys and gibbons.

            We spent one night in the jungle after the exhausting trek over mountains and through rivers. From Bukit Lawang, we traveled to Brastagi and climbed Gunung Sibayak. Then, we went to Toba Lake enjoying the beach of Samosir Island. What a great experience!

Pertanyaan2nya adalah:

1.   What does the text tell you about?

      a.   Culture divergence in Sumatra

      b.   The amazing view in Sumatra Island

      c.   The traveling guidance for the visitors

      d.   The trip to the North Sumatra and West Sumatra

      Yg betul B / D ya, Pak/Bu?

2.   Where did the writer and his friends stay when they visited Bukit      Lawang?

      a.   In a small house

      b.   In a good motel

      c.   At the luxurious hotel

      d.   In the nut near the river

      Yg betul A / D ya, Pak/Bu? Apakah yg dimaksud dng “hotel”             di bacaan tsb diatas ya, Pak/Bu?

Jawaban no. 1 D karena teks diatas menceritakan tentang perjalanan penulis ke Sumatera.

Jawaban no. 2 D karena konteks ' hotel ' didalam teks tsb adalah a hut ( not a nut ) near the river.
