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!
Despite their many similarities, mitochondria (and chloroplasts) aren't free-living bacteria anymore. The first eukaryotic cell evolved more than a billion years ago. Since then, these organelles have become completely dependent on their host cells. Membranes  Mitochondria have their own cell membranes, just like a prokaryotic cell does. 2  DNA  Each mitochondrion has its own circular DNA genome, like a bacteria's genome, but much smaller. 3  This DNA is passed from a mitochondrion to its offspring and is separate from the host cell's genome in the nucleus.
