Which row correctly matches the functional and structural features of cellulose, collagen, glycogen or triglyceride? [Figure 11.1 - table matching functional and structural features of molecules]
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Acellulose: function: support, fibrous: true, molecules held together by hydrogen bonds: true, branched chains: false; triglyceride: function: energy source, fibrous: false, molecules held together by hydrogen bonds: false, branched chains: false
Bcollagen: function: strengthening, fibrous: true, molecules held together by hydrogen bonds: true, branched chains: false; cellulose: function: support, fibrous: true, molecules held together by hydrogen bonds: true, branched chains: false
Ccollagen: function: strengthening, fibrous: true, molecules held together by hydrogen bonds: false, branched chains: false; glycogen: function: storage, fibrous: false, molecules held together by hydrogen bonds: false, branched chains: true
Dglycogen: function: storage, fibrous: false, molecules held together by hydrogen bonds: false, branched chains: true; triglyceride: function: energy source, fibrous: false, molecules held together by hydrogen bonds: false, branched chains: false
✓ Correct answer
A: cellulose: function: support, fibrous: true, molecules held together by hydrogen bonds: true, branched chains: false; triglyceride: function: energy source, fibrous: false, molecules held together by hydrogen bonds: false, branched chains: false
