You are growing plants hydroponically (rooted in an aqueous solution rather than soil). The solution for the control group of plants contains normal levels of salts and nutrients, while the solution for the treatment group has a high concentration of large molecular weight solutes that are excluded by roots. You find that the plants in the treatment group are on average smaller than those in the control group, but there is no significant difference between the groups in the amount of CO2 being fixed by the average plant. What differences at the cellular level between groups would you expect to make an important contribution to the difference in size of the shoots?A. The total number of cells in the treatment group shoots would be smaller. B. The girth of cells in the elongation and mature zones would be larger in the control group. C. Cellulose molecules would be more randomly oriented in mature cell walls in the treatment group. D. Auxin levels and cell wall extensibility would be lower in the treatment group. E. The length of cells in the elongation and mature zones would be larger in the control group.

Penicillin is hydrolyzed and thereby rendered inactive by penicillinase (also known as β-lactamase), an enzyme present in some resistant bacteria. the mass of this enzyme in staphylococcus aureus is 29.6 kd. the amount of penicillin hydrolyzed in 1 minute in a 10-ml solution containing 10-9 g of purified penicillinase was measured as a function of the concentration of penicillin. assume that the concentration of penicillin does not change appreciably during the assay. penicillin(μm) amount hydrolyzed(nmol) 1 0.11 3 0.25 5 0.34 10 0.45 30 0.58 50 0.61 (a) plot v0 versus [s] and 1/v0 versus 1/[s] for these data. does penicillinase appear to obey michaelis-menten kinetics? if so, what is the value of km? (b) what is the value of vmax? (c) what is the turnover number of penicillinase under these experimental conditions? assume one active site per enzyme molecule.
