Carbohydrate (4%). Protein (19%). Lipid (15%). Vitamins & Minerals, and Nucleic Acids (2% collectively). Water (60%). 1 of 14 What is the role of carbohydrates? Energy store & supply. Can have structural roles. 2 of 14 What is the role of protein? Can have structural roles. Used in metabolism. 3 of 14 What is the role of lipids? Energy store & supply. Insulation. Membrane structure. Protection of organs. 4 of 14 What is the role of vitamins and minerals? Needed to activate some enzymes in the body. 5 of 14 What is the role of nucleic acids? Carry the genetic code & instructions for protein synthesis. 6 of 14 What is the role of water? It's a solvent which dissolves substances for reactions to take place. Makes up a large proportion of blood plasma and cell cytoplasm. 7 of 14 What is biochemistry? Chemical reactions involving biological molecules. 8 of 14 What is metabolism? Refers to the total of all the biochemical reactions occurring in an organism. 9 of 14 What is a catabolic reaction? Reactions involving breaking larger molecules into smaller ones. Eg: digestion. 10 of 14 What is an anabolic reaction? Reactions involving building smaller molecules into larger ones. Eg: joining glucose into glycogen. 11 of 14 What feature makes carbon a framework atom? Its multiple bonding feature means it can form the basis of most biological molecules necessary for life. 12 of 14 What is a condensation reaction? Biochemical reaction that links monomers together. Water is lost. 13 of 14 What is a hydrolysis reaction? Biochemical reaction involved in splitting a large molecule into smaller ones. 14 of 14
