5 Asrtylcholise s releasol to help musles relax Once it hs tiggered the next neuton.it is down by the enayme acetylcholinesterase, to maintain muscle control ynapee a) Use the diagram below to label the reactants and products using ACh-Acetylcholine. Ch choline, and A acetate a) a) a) b) What classification of enzyme is acetylcholinesterase- oxidoreductase, isomerase. ligse, lyase, hydrolase, or transferase c) Atropine is found in plants call evening nightshades. Tomatoes, potatoes, and eggplants are all members of the evening nightshades. Atropine is used to accelerate a slow heart rate by activating the acetylcholine receptors of the enzyme, acetylcholinesterase. Does this information tell us that atropine interacts at the active site or allosteric site of acetylcholinesterase

Explanation / Answer

Acetylcholine is the neurotransmitter, assit is signaling across nerves synapse. It is basically helpful in passing messages of brain.

CH3-COO- CH2-CH2-N+(CH3)3 ---------------------------------> OH-CH2-CH2-N+(CH3)3 + CH3-COO-

    ACh                                                                            Ch                             A

Oxidoreductase is used for catalysing oxidation-reduction reactions.

Transferase is used for catalysing functional group transfers.

Hydrolase is used for catalysing hydrolysis reactions.

Lyase catalyzes elimination or addition of groups to form or break double bond.

Isomerase catalyse reaction that alter structure, not composition.

Ligase catalyse coupling of two compounds along with hydrolysis of phosphoanhydride bond.

Atorpine is non selective competitive antagonist means it binds or blocks a receptor rather than activating it. Basically, competitive anatagonist binds to same receptor site where agonist has to bind. It does not activate the receptor. Sufficient concentration of antagonist displace the agonist from the binding sites results in low receptor activation. Atropine interacts at the active site.
