Question 4 SPM Paper 2 2010

The suggested answer for this Question might help you ..Nur..Please refer to Paper2 SPM2010

4(a)

X-primary structure

Y-Secondary structure

(b)

The linear sequence of amino acids in the polypeptide chain./ Jujukan linear asid amino dalam rantai polipeptida.

(c)

Protein X is broken down by an enzyme/ polypeptidase in a process of hydrolysis to form dipeptide.

Protein X dihidrolisiskan oleh enzim /polipeptidase membentuk dipeptida.

(d)

Because it contains all 8 essential amino acids needed by humans.

Sebab ia mengandungi 8 asid amino perlu yang diperlukan oleh manusia.

(e)(i)

Silk is a protein fiber. High temperature will reduce the strength of hydrogen bonds, so this will distrupt the structure , thus denature proteins.

Sutera adalah fiber protein. Suhu yang tinggi akan mengurangkan kekuatan ikatan hydrogen, ini akan mengganggu struktur protein lalu menyebabkan denaturasi.

(ii)

Wash it in a cold water./ Basuh dalam air sejuk

Do not wring..

Do not expose to direct sunlight./ elak dedah terus kepada cahaya matahari

Never use chlorine bleach on silk. / jangan menggunakan bahan peluntur klorin
