In the human stomach, chemical reactions take place in an acidic environment. Some of these reactions are catalyzed by enzymes. How would these enzymes most likely function in an environment where the pH was doubled? The rate of the reactions that are catalyzed by the enzymes would double.
The rate of the reactions would increase as the pH is increased.
The enzymes would not be able to function properly outside of their optimal pH range.
The enzymes would interfere with chemical reactions by bonding with the reactants.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

a

explanation:

tissue

explanation:

it is actually formed by geoup of cells which is tissue

the tricuspid valve is present between right atrium and right ventricle
