What happens when a suitable substrate binds to an enzyme? - ANSWER-The active site amino acids bond with the substrate Cyanide binds to cytochrome oxidase at a site where the substrate oxygen would normally bind. This is an example of - ANSWER-competitive inhibition an example of a catabolic reaction is - ANSWER-lactate fermentation what is an anabolic process that is endergonic and endothermic? - ANSWER-CH₄ +2O₂ → CO₂ + 2H₂O ATP yields 7.3 kcal/mol of free energy and it i...

BIO 311C FINAL QUESTIONS AND ANSWERS A+ GRADED Two black guinea pigs were mated and they produced 14 black and 6 white offspring. Based on the results what are the genotypes of the parent pigs? A) Homozygous dominant B)Heterozygous dominant C) Homozygous recessive D) Heterozygous recessive E) Hemizygous dominant B)Heterozygous dominant almost 3/4 of offspring were black so this is the dominant trait and since white offspring occurred (~25%) we know that the parents must both h...
