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!
After all, every cell in your body (except mature red blood cell, which have no nuclei, and egg cells) has the same DNA in its nucleus. Why would mitochondria need. The best story we have now is that mitochondria are actually the descendants of bacteria that hitched a ride in larger, more complex cells. Our cells, and those of plants, amoeba-type things, and fungi, are eukaryotic.. Bacterial cells are called prokaryotic.. They don't have nuclei, they are much smaller than our cells, and don't have organelles like our cells. Perhaps the tiny prokaryotes invaded early eukaryotes a long time ago (like 1.4 billion years ago) in order to absorb their food, acting like parasites.
