1 Cholinesterase inhibitor toxicity is due to a decrease in the ability of cholinesterase to breakdown acetylcholine which results in excessively high acetylcholine levels. 2  Cholinesterase inhibitors fall into two classes, organophosphorus compounds, and carbamates.ow Acetylcholine is Blocked (Optional Reading). Figure 2 below shows how a cholinesterase inhibitor (in this case, a nerve agent) attaches to the serine hydroxyl group on acetylcholinesterase.
(Âµm micrometers) A single mitochondrion- 0.2-1 Âµm wide x3-10 Âµm long (can differ very much depending on the cell) Chloroplasts - 3 Âµm wide x 5 Âµm long As you can see mitochondria can often be bigger than bacteria cells... and viruses are way smaller then bacteria!Âµm micrometers) A single mitochondrion- 0.2-1 Âµm wide x3-10 Âµm long (can differ very much depending on the cell) Chloroplasts - 3 Âµm wide x 5 Âµm long As you can see mitochondria can often be bigger than bacteria cells... and viruses are way smaller then bacteria!
While all bacterial cell walls (with a few exceptions e.g. extracellular parasites such as Mycoplasma) contain peptidoglycan, not all cell walls have the same overall structures. Since the cell wall is required for bacterial survival, but is absent in some eukaryotes, several antibiotics (notably the penicillins and cephalosporins) stop bacterial infections by interfering with cell wall synthesis, while having no effects on human cells which have no cell wall only a cell membrane. There are two main types of bacterial cell walls, those of gram-positive bacteria and those of gram-negative bacteria, which are differentiated by their Gram staining characteristics. For both these types of bacteria, particles of approximately 2 nm can pass through the peptidoglycan.
