The role of microorganisms such as yeast in the environment is that these contain bacteria which are the workhorses of biological processes such as fermentation to produce metabolites that are beneficial to the body. An example of this is the fermentation of any fruit (or substances containing sugar) to produce metabolites such as alcohol, aldehydes, acids (lactic or acetic acid) and many more via the action of yeast bacteria, commonly <em>Saccharomyces cerevisiae</em>. Pollutants affect the functions of yeast as they play as contaminants of the living workhorses.Pollutants can introduce disturbances which affect how yeasts strive in the environment. This affects the production of metabolites as well.

andrezito [222]

Answer:

Explanation:

A. False - A symporter system requires that one of the molecules to be transported using passive transport.

B. True - The Na+ will move down the established concentration gradient releasing energy to facilitate movement of sucrose against its concentration gradient. This is known as secondary active transport.

C.  False -  sucrose moves through ion channels not by diffusion to better control its movement across the membrane.

D. True - Movement of molecules against their concentration gradient thus requiring energy input is known as active transport.

E. False - One of the molecules needs to be moving against its concentration gradient.

F. False - A Uniporter system allows the binding and transport of a single molecule at a time. A symporter allows simultaneous binding and transport of Na+ and sucrose molecules.
