Answer:
Explanation:
<h2>
Homotropic effector-</h2>
<h2>Both -</h2>
The phrase 
is relevant and can be applied for homotropic effector molecules since the heterotropic effector molecules have the possibility and affinity to change the sigmoidal curve to a more potential hyperbolic curve contingent upon the allosteric effector to be positive or negative modulator.
The expression isn't relevant for both homotropic and heterotrophic effectors since the two of them can tie to the allosteric site of allosteric enzymatic compounds.
The phrase 
is significant and can be applied for both homotropic and heterotropic effectors.
The expression 
is significant and applied for homotropic effectors just as when substrate molecules tie to the allosteric site of enzyme then it is regarded as homotropic effectors. The heterotropic effectors are effectors apart from substrate molecules.
The phrase 
is not applied and insignificant to none of the heterotropic or homotropic effector molecules since 
is significant for the enzymes that obey the Michaelis-Menten equation, but allosteric enzymes do not obey the Michaelis-Menten equation. Homotropic and heterotropic effectors are viable and efficient for allosteric enzymatic chemicals that don't contain
That would be A.
Most antibiotics that are used for gram positive bacteria target the peptidoglycan cell wall, but the ones for gram negative bacteria are more advanced and specific and target the cell membrane and alter the cell’s function(processes of proteins and dna/gene expression).
