-3(3f+4s=523)+(9f+3s=507)

-9f-12s+9f+3s=-1569+507

-9s=-1062

s=118,  making 3f+4s=523 become:

3f+472=523

3f=51

f=17

So the reels are $17 each and the rods are $118 each.

The KM values for the reaction of chymotrypsin with 2 substrates are given below. Which substrate is likely to give a higher val
Mrrafil [7]

N-acetyltyrosine ethyl ester may likely have a higher Vmax.

<h3>How are the Km and Vmax of an enzyme and substrate related?</h3>

Km is inversely proportional enzyme affinity for substrate. The lower the Km, the higher the enzyme affinity for substrate and vice versa.

Vmax is the maximum velocity of the reaction when the enzyme is fully saturated with substrate.

Based on the Km values, chymotrypsin has higher affinity for N-acetyltyrosine ethyl ester, thus, N-acetyltyrosine ethyl ester may likely have a higher Vmax.

In conclusion, the Vmax is the maximum velocity of an enzyme-catalyzed reaction.

<em>Note that the complete question is given below:</em>

<em>The Km for the reaction of chymotrypsin with N-acetylvaline ethyl ester is 8.8 x 10-2 M, and the Km for the reaction of chymotrypsin with N-acetyltyrosine ethyl ester is 6.6 x 10-4 M.</em>

<em>Which of the following substrates is likely to give a higher value for Vmax?</em>

Nine out of ten students prefer math class over lunch. How many students do not prefer math if 200 students were asked?
fredd [130]
So, 9 out of 10 students prefer class, so, obviously, it would not be 100. It would be 150. So in conclusion, 50 students prefer lunch over math class, whilst 150 other students prefer math class over lunch.
