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!
The Single Cell I'm going to start with unicellular organisms. A bacterium is typically 4-8 micrometres in length. Yeast is typically 3-4 micrometres in diameter, but the largest yeast cells can be up to 40 micrometres. A human ovum is 0.1mm in diameter. The largest bacterium known is Thiomargarita namibiensis, which can be up to 0.75mm in diameter, and can be seen with the naked eye.
