In 1918, an epidemic of sleeping sickness caused an unusual rigid paralysis in some survivors, similar to symptoms of advanced parkinson’s disease. years later, l-dopa, a chemical used to treat parkinson’s disease was given to some of these patients. l-dopa was remarkably effective at eliminating the paralysis, at least temporarily. however, its enantiomer, d-dopa, was subsequently shown to have no effect at all, as is the case for parkinson’s disease. in a short essay discuss how tne effectiveness of one enantimer and the other illustrates the theme structure and function, discuss how the effectiveness of one enantiomer and not the other illustrates the theme of structure and function.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.
