You are comparing two strains, A and B. Strain A uses the Entner-Doudoroff Pathway to produce pyruvate from glucose. Strain B uses the Embden-Meyerhof-Parnas Pathway to produce pyruvate from glucose. Assume the growth of each strain is directly proportional to the amount of ATP each pathway can produce. After 8 hours of growth on identical media containing glucose and other molecules required for growth, which strain do you expect have a HIGHER optical density?a. They will be equal. b. Strain A
c. Strain B
d. Neither strain will grow.

The two tubes contain bromothymol blue. after 24 hours, what will the color of the water be in tube b? a. green (it won't change) b. yellow c. blue d. colorless (clear)

1. an enzyme is considered a(n) because it speeds up a chemical reaction without being used up.2. in a catalyzed reaction, a reactant is often called a(n) . an enzyme is specific because the shape of its matches only particular reactants.4. an enzyme speeds up reactions by lowering the . the between an active site and its substrate often strains bonds and the reaction proceed.6. a( , which is often a vitamin, binds to an enzyme and plays a role in catalysis.7. high temperatures or changes in ph can an enzyme, causing it to lose its shape and biological activity.

1. mendel observed that pea plants had traits, such as color, that were either “one or the other,” never something in between. discuss the correlation between mendel’s factors, what they might be, and why pea plant traits come in one form or another—e. g., gray or dark red—rather than blended.
