Wild- Type Bacteria Can Grow on Minimal Medium

question 39

Multiple Choice

Wild- type bacteria can grow on minimal medium. Four mutants that cannot grow on minimal med but can grow on minimal medium supplemented with the nutrient "H" are isolated. It is suspected t metabolites T, P, and A are in the biochemical pathway for synthesis of H, so each mutant is tested f ability to grow on minimal medium supplemented with these metabolites:
A. Mutant 1: can grow on minimal medium supplemented with T, but not P or A
B. Mutant 2: is unable to grow on minimal medium supplemented with T, P, or A
C. Mutant 3: is able to grow on minimal medium supplemented with A or T, but not P
D. Mutant 4: can grow on minimal medium supplemented with T, P, or A.
Which of the following is NOT consistent with this information?

• A) Mutant 1 will cause a build up of metabolite A
• B) Mutant 4 blocks a step before all the metabolites
• C) Mutant 3 blocks the conversion of metabolite P →metabolite A
• D) Mutant 3 will cause a build up of metabolite T
• E) Mutant 2 blocks a step right before metabolite H

Definitions:

Average Service Rate

The average number of customers or units that can be processed over a certain time frame in a service system.

Expected to Stay

An estimation of the duration or likelihood that an individual or item remains in a particular state or location.

M/D/1

M/D/1 is a queueing model designation indicating a system with a Poisson arrival process (M), deterministic service times (D), a single server (1), and exponential service times.

Constant Service Time

A situation where the time required to serve a customer or complete a process is the same each time, allowing for predictable scheduling and planning.
