Strong bonds 1 of 18 Hydrogen Bond Weak interaction that occurs when a negatively charged atom is bonded to a positively charged hydrogen 2 of 18 Molecular biology The study of structure and functioning of biological molecules 3 of 18 Metabolism Sum total of all biochemical reactions in the body 4 of 18 Things needed to maintain a healthy body Carbohydrates. Lipids. Proteins. Vitamins and minerals. Nucleic acid. Water. Fiber. 5 of 18 What are the 4 key biological molecules? Carbohydrates. Lipids. Proteins. Nucleic acids. 6 of 18 What are the four most common elements in the living organism? Hydrogen. Carbon. Oxygen. Nitrogen. 7 of 18 What do covalent bonds do? Join atoms together to form molecules 8 of 18 How many bonds is carbon able to make? Four 9 of 18 What is a monomer? A molecule that can react with another molecule of the same type to form a polymer. 10 of 18 What is a polymer? A repeating chain of monomers 11 of 18 What is a macro molecule? Macro molecules are made up if repeating subunits that are joined end to end, they are easy to make as the same reaction is repeated many times 12 of 18 What is polymerisation? The making of a polymer/s 13 of 18 What is the macro molecule for these three monomers? Monosaccharide. Amino acid. Nucleotide. Polysaccharide. Proteins. Nucleic acid. 14 of 18 What is anabolism? Build up of larger more complex molecules from smaller simpler ones. It is a process that requires energy 15 of 18 What is catabolism? The breakdown of complex molecules into simpler ones. This process releases energy. 16 of 18 What happens in a condensation reaction? A water molecule is released. A new covalent bond is formed. A larger molecule is formed by bonding together smaller molecules. 17 of 18 What happens in a hydrolysis reaction? A water molecule is used. A covalent bond is broken. Smaller molecules are formed by the splitting of a larger molecule. 18 of 18
