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!
Evidence that mitochondria and chloroplasts arose via an ancient endosymbiosis of a bacteria is as follows: 1  Both mitochondria and chloroplasts contain DNA, which is fairly different from that of the cell nucleus, and that is similar to that of bacteria (in being circular and in its size).he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).
