If using a cotransporter for movement of two molecules, what would happen if one molecule could no longer bind to the transporter?

Solutions

Expert Solution

Answer: The transport does not occur
Explanation:
Cotransport = Coupled transport of two molecules.
It is two types based on the direction of molecular transport.

Symport: Both the molecules are transported in the same direction.
Ex: Glucose-Na+ symporter

Antiport: Both molecules are transported in opposite directions to each other.
Ex: Na+:K+ antiport

It is a carrier-mediated coupled transport. i.e. the movement of molecules is dependent upon each other. If one of the molecules does not bind to the carrier protein, the transport of the other molecule does not occur. i.e. the carrier protein mechanism operates in such a way that it cannot mediate the transport of a single molecule.

When one glucose molecule enters the glycolytic pathway, two molecules of pyruvate are created. This change in stoichiometry is ultimately due to the actions of: A. hexokinase, which phosphorylates the glucose molecule. B. phosphofructokinase-1, which creates a doubly-phosphorylated fructose molecule. C. aldolase, which cleaves the doubly-phosphorylated fructose molecule into two different 3-carbon molecules. D. triose phosphate isomerase, which catalyzes the rearrangement of bonds within one dihydroxyacetone phosphate molecule. E. phosphoglycerate kinase, which dephosphorylates two molecules of 1,3-bisphosphoglycerate.

The “equilibrium” in hydrostatic equilibruim can be understood by imagining what would happen if we could somehow squeeze the Sun (add an outer layer to increase mass).
