The active site forms as the enzyme and substrate interact 1 of 14 What are competitive inhibitiors? They are molecules that bind to the active site of the enzyme 2 of 14 What are non-competitive inhibitors? They are molecules that bind to the enzyme at a position other than the active site 3 of 14 What are the four bases? Adenine, Guanine, Cytosine, Thymine 4 of 14 What makes up a nucleotide? A phosphate group, pentose sugar and an organic base 5 of 14 What base is adenine complementary to? Thymine 6 of 14 What base is guanine complementary to? Cytosine 7 of 14 Why is DNA stable? The phosphodiester backbone protects the bases inside the double helix 8 of 14 What is cytokinesis? It follows nuclear division and is the process by which the whole cell divides 9 of 14 What four requirements are needed for semi-conservative replication to take place? Four types of nucleotides present, Enzymme polymerase, Both strands of the DNA molecule act as a template and a source of chemmical energy is required 10 of 14 `What enzyme breaks the hydrogen bonds linking the base pairs of DNA? DNA helicase 11 of 14 What is ATP used for? Metabolic processes, movement, active transport, secretion and activation of molecules 12 of 14 What makes up an ATP molecule? Adenine. Ribose and Phosphates 13 of 14 What are some qualities of water? High surface tension, latent heat of vaporisation, specific heat capacity, used in metabolism and as a solvent 14 of 14
