What is it called when the final product of an enzymatic pathway acts as a modulator for the first enzyme in the pathway? a. isoenzyme activation b. relative specificity c. feed back inhibition d. competitive inhibition

D. Question 14 Consider the Lineweaver-Burk plots of two enzyme activities on the left. How is enzyme A different from enzyme B? 1/v B 1/[S] O Enzyme A has a negative Km O Enzyme A requires more substrate to achieve the same rate O Enzyme A has a smaller Km/Vm ratio Enzvme A is slower

Why does the velocity reach a plateau (asymptote) at high substrate concentrations?       a. At high substrate concentrations, the product becomes an inhibitor of the reaction that created it.       b. At high substrate concentrations, all enzymes are saturated with substrates.       c. At high substrate concentrations, all substrates have been converted to products.       d. At high substrate concentrations, the product concentration is high and the reaction starts running in reverse.

Since the air bubbles in bread are generated by yeast, how will the spaces in this bread compare to those in a loaf made using normal yeast?   A. more bubbles    B. differently-shaped bubbles   C. smaller bubbles   D. bubbles more on the interior of the loaf
