Very quick rehash (review): 1  genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. 2  A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).tep #4: Split the letters of the genotype for each parent & put them outside the p-square. 1  For an example cross we'll use these parental genotypes: Tt x tt. 2  Take the genotype letters of one parent, split them and put them on the left, outside the rows of the p-square.
II. Most enzymes are proteins. A. Protein enzymes have specific three-dimensional shapes, which are determined by the amino acid sequence and, ultimately, by the genes. B. The reactants in an enzyme-catalyzed reaction, called the substrates of the enzyme, fit into a specific pocket in the enzyme called the active site.he activation energy is the amount of energy needed by the reactant molecules to participate in a reaction. 2. In the absence of a catalyst, only a small proportion of the reactants possess the activation energy to participate in the reaction. 3.
