3. which of the following correctly list substances from least permeable to the most permeable across a lipid bilayer?
Which of the following correctly list substances from least permeable to the most permeable across a lipid bilayer?
(Dari daftar berikut dari yang paling tidak permeable ke paling permeabel dalam menembus lapisan lipid bilayer adalah?)
D. Potassium ions, glucose, glycerol, water, oxygen
Pembahasan:
Permeabilitas adalah ukuran mudah atau sulitnya suatu partikel menembus suatu lapisan membran.
Beberapa faktor yang mempengaruhi permeabilitas adalah:
Ukuran partikel: Semakin besar ukuran partikel maka semakin susah menembus lapisan membran pemeable. Sementara partikel berukuran kecil mudah menembusnya. Muatan partikel: Ion bermuatan lebih susah menembus lapisan membran pemeable, bila dibanding partikel bermuatan netral. partikel bermuatan psotif semakin susah lagi menembus lapisan ini, dibanding, partikel bermuatan negatif. Sifat hidrofobik: Gas terlarut seperti O2 dan CO2, yang bersifat hidrofobik (biasanya adalah partikel tidak bermuatan dan berbentuk simetris), akan memiliki permeabilitas tinggi.Dalam soal ini, urutan dari yang memiliki permeabilitas paling kecil adalah:
Potassium ions: Ion potasium adalah ion K+. Sebagai partikel bermuatan positif, maka partikel ini memiliki permeabilitas sangat rendah. Karena ada resistensi terhadap ion K + dalam melintasi membran, diperlukan transpor aktif untuk memindahkan ion ini. Glucose: Glukosa memiliki rumus C6H12O6, dengan kata lain, partikel ini berukuran besar sebab jumlah atom penyusunnya yang banyak. Selain itu, glukosa juga bersifat polar, atau memiliki muatan akibat strukturnya yang tidak simetris. Ini membuat glukosa memiliki permeabilitas rendah. Glycerol: Gliserol memiliki rumus C3H8O3. Ukuran partikel gliserol lebih kecil dari glukosa. Sehingga permeabilitasnya lebih besar dari glukosa Water: Air memiliki rumus H2O. Ukuran partikel air lebih kecil dari gliserol dan glukosa. Sehingga permeabilitasnya lebih besar dari gliserol dan glukosa. Oxygen: Oksigen memiliki rumus O2. Ukuran partikelnya yang kecil, ditambah lagi karena oksigen bersifat hidrofobik, membuat oksigen sangat besar permeabilitasnya.Pelajari lebih lanjut:
