C) A cell membrane.
Bacteria are unicellular and do not have a nucleus.
i hope i helped:)
That isn't even possible. Your body is made of them. If you had none then you wouldn't be existing.
The third choice im pretty sure
i hope this helps!!
Answer:
I'm not sure but I think it should be the enzyme inhibitor binds to the products of the reaction which makes the enzyme unproductive
Explanation:
By binding to enzymes' active sites, inhibitors reduce the compatibility of substrate and enzyme and this leads to the inhibition of Enzyme-Substrate complexes' formation, preventing the catalyzation of reactions and decreasing (at times to zero) the amount of product produced by a reaction. It can be said that as the concentration of enzyme inhibitors increases, the rate of enzyme activity decreases, and thus, the amount of product produced is inversely proportional to the concentration of inhibitor molecules. Since blocking an enzyme's activity can kill a pathogen or correct a metabolic imbalance, many drugs are enzyme inhibitors. The binding of an inhibitor can stop a substrate from entering the enzyme's active site and/or hinder the enzyme from catalyzing its reaction. Inhibitor binding is either reversible or irreversible. Irreversible inhibitors usually react with the enzyme and change it chemically (e.g. via covalent bond formation).
Blood Vessels. Blood is used to transport respiratory gases ( oxygen / carbon dioxide ) between the gills and respiring cells around the body. :))
