Question

ons 19 and 21 refer to the biochemical pathway and supplementation table the following biochemical pathway ou are examining ndicated by letters over the arrows: , which is catalyzed bry the enaymes Glacose (G) A glucose6-phosphate (06P)--+ fructose 6-phosphate (P6P) 3-phosphate (G3P)fructose 1 s-phosphate (FI 5P) You have 4 strains, each with a mutation in a different enzyme the in the pathway, You supplement strains with one of the strains can products in the pathway (G, G6P, F6P. F1.6P. G3P) to see which rodpoduce G3P with the supplement (+ indicates can produce G3P.- indicates cannot ee G3p). You have mixed up the media supplements (G, G6P. F6P. F1.6P. G3P), so you label the supplements as i-v. You find the following: media supplement straini Question 19. Which strain has a mutation in B? a. 1 b. 2 d. 4 e. none Question 20. Which strain has a mutation in C? a. b. 2 c. 3 e none Question 21. To which media supplement does 'i' correspond? b. G6P c. F6P d. F1,6P e. G3P

Explanation / Answer

media supplements

So the order of the pathway is iv ----> i ----> iii ----> v ----> ----> ii

media supplements

strain i ii iii iv v 1 + 2
+ 3 + 4 +
