Sample VCE Biology Exam Questions Question 1 (Q1, 2007) A polysaccharide that can be made in some animal cells is A. starch. B. pectin. C. glycogen. D. cellulose.
Question 2 (Q4, 2007) A protein-based fibre could be constructed from repeated monomers of A. C 5 H 13 N 4 COOH B. CH 3 (CH 2 ) n COOH C. C x (H 2 O) y D. C 6 H 5 COCl
Question 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 if A. X is ribose. B. Z is thymine. C. Y is phosphate. D. Z paired with cytosine.
Question 4 (Q20, 2007) Cell organelles and membranes that are involved in the transport of biomolecules from inside a cell to outside a cell include A. ribosomes. B. microtubules. C. membranes that form vesicles during endocytosis. D. secretory vesicles that bud off from the Golgi complex.
Short answer (Q6a 2007) During digestion, large molecules are broken down into their constituent monomers (subunits). a. Complete the table below. Large moleculesMonomers (subunits) Amino acids Lipid Monosaccharide DNA
Answers Q1 – C Q2 – A Q3 – B Q4 – A SA a) Protein – amino acid Lipid – Fatty acid/ FA& Glycerol OR no monomer Polysaccaride – monosaccaride DNA – Nucleotide B) monosaccarides move by facilitated diffusion of active transport via protein channels of protein carrier molecules
