1 Bloomfield all School Test (Unit 2) Name :... Paper: Biolog y Date :... lass: A1&2 Time Allowed: 40Minutes Maximum Marks: 2 TKheory Section: [Total 16 Marks] 1 aemoglobin is a globular protein that shows quaternary structure. It is composed of two types of polypeptide, known as α and β globin. (a) Explain how a globular protein differs from a fibrous protein, such as collagen. Dedicated to Mohammad Irtaza aider Zain. 1...[2] Fig.1.1 shows part of the base sequence of the mrna that codes for the first ten amino acids of β globin. Table 6.1 shows some of the codons and the amino acids for which they code. GUG A UG AU U GAG GAG AAG UU G (b) Fig.1.1 Table 1.1 amino acid abbreviation codons alanine ala GA G GG GU glutamic acid glu GAA GAG histidine his A AU leucine leu UUA UUG UA U UG UU lysine lys AAA AAG proline pro A G U serine ser UA U UG UU AG AGU threonine thr AA A AG AU valine val GUA GU GUG GUU Use the information in Table 1.1 to complete the sequence of amino acids at the beginning of β globin using the first three letters of each amino acid. Some of them have been done for you. val his glu ala [2]
2 (c) 2 β globin has a tertiary structure that consists of eight helices arranged to give a precise three-dimensional shape. Describe how the precise three-dimensional shape of a polypeptide is maintained....[4] [Total: 8] 2 Fig. 2.1 shows a β glucose molecule Fig. 2.1 (a) State how α glucose differs from β glucose as shown in Fig [1] 1 (b) Fig. 2.2 shows a molecule of β glucose that is about to be added to the end of a growing chain of a polysaccharide. (i) Name the bond E. E Fig [1] Dedicated to Mohammad Irtaza aider Zain.
3 (ii) 3 Use the diagram below to show how the β glucose molecule will attach to the end of the growing chain of the polysaccharide. You may annotate the diagram if you wish. (c) (iii) Name a polysaccharide that is formed entirely from β glucose molecules in the way shown in Fig [1] A solution of starch was poured into six separate test-tubes, labelled F to K. The testtubes were kept at 3 for minutes and then treated as shown in Table 2.1. After a further 30 minutes the contents of the test-tubes were tested for the presence of reducing sugar. Table 2.1 [2] presence or absence of test-tubes substances added after minutes reducing sugar after 30 minutes F distilled water absent G amylase + boiled maltase present amylase + distilled water present I boiled amylase + maltase absent J amylase + maltase present K maltase + distilled water absent Explain the results shown in Table 2.1. Dedicated to Mohammad Irtaza aider Zain.
