2Question 2 (Q4, 2007)A protein-based fibre could be constructed from repeated monomers ofA. C5H13N4COOHB. CH3(CH2)nCOOHC. Cx(H2O)yD. C6H5COCl
3Question 3 (Q9, 2007)The following diagram represents a nucleotide with subunits X, Y and Z.This nucleotide could be identified as a monomer of DNA but not RNA ifA. X is ribose.B. Z is thymine.C. Y is phosphate.D. Z paired with cytosine.
4Question 4 (Q20, 2007) A. ribosomes. B. microtubules. Cell organelles and membranes that are involved in the transport of biomolecules from inside a cell to outside a cell includeA. ribosomes.B. microtubules.C. membranes that form vesicles during endocytosis.D. secretory vesicles that bud off from the Golgi complex.
5Short answer (Q6a 2007) a. Complete the table below. During digestion, large molecules are broken down into their constituent monomers (subunits).a. Complete the table below.Large moleculesMonomers (subunits)Amino acidsLipidMonosaccharideDNA
6Answers Q1 – C Q2 – A Q3 – B Q4 – A SA a) Protein – amino acid Lipid – Fatty acid/ FA& Glycerol OR no monomerPolysaccaride – monosaccarideDNA – NucleotideB) monosaccarides move by facilitated diffusion of active transport via protein channels of protein carrier molecules
