What is a protein channel?
aliya0001 [1]
<span>Protein channels are needed to transport substances because it accelerates the transport process. Very few substances enter or leave cells without being attached to a transport protein. Different types of substances require different types of proteins to transport them. Protein channels transport water or ions downwards and ATP-powered pumps transport molecules or ions upwards. ATP generates energy to transport the molecules upwards. Gravity is used to transport the water molecules downwards. So, in a nutshell, if substances need to be transported from the top of the body downward, the force of gravity is used to transport the substances down. If substances need to be transported upwards, ATP, a coenzyme, is used to generate energy to transport the substance upwards</span>

You are studying a biochemical pathway and isolate mutants I, II, and III. Mutant I can grow if you supplement the medium with Z
bekas [8.4K]

Answer:

d) Y, X, Z

Explanation:

Mutant I only grows when the medium is supplemented with Z. So Z is the final product of biochemical pathway since supplying other intermediates do not lead to any growth.

Mutant III can grow if medium is supplemented with X and Z but not with Y. This means that Y is the first intermediate in this pathway since mutant III is not able to convert it into X and hence needs to be supplemented with next intermediate product X for growth.

Hence the correct order of X, Y and Z in this biochemical pathway is Y, X, Z.
