Binding with an alternate neurotransmitter would inhibit the reaction of the enzyme with acetylcholine.
Reacting with another neurotransmitter would halt the production of the enzyme and raise the overall activation energy.
Its shape determines the neurotransmitters that can reach its active center where activation energy is lowered.
I think it might be the last one

Answer:C
Explanation:
Answer:
A
Explanation:
The reason the deletion of a nucleotide can be a lethal mutation is that it causes a frameshift mutation. This is due to teh fact that the codon sequence on the DNA is shifted by a single nucleotide. Therefore, the codons will read differently downstream from the place the deletion happened. The amino acids coded for by these codons will change too. The translated proteins will be defective and the organisms will be adversely affected, phenotypically.
The most dangerous mutation to a cell among the given choices would be the deletion of one nucleotide. This could result in a frameshift mutation, which can change every subsequent codon and potentially lead to a non-functional protein.
In the context of mutations and their potential harm to a cell, between the options of deletion of one nucleotide, deletion of three nucleotides, or substitution of one nucleotide for another, the most dangerous would likely be the deletion of one nucleotide.
Mutations including deletions or insertions can cause a frameshift mutation if the number of nucleotides added or deleted is not a multiple of three. For each set of three nucleotides, called a codon, corresponds to a single amino acid. A deletion of one nucleotide would shift the reading frame, potentially changing every subsequent codon and thus every subsequent amino acid in the sequence. This can result in a non-functional protein, and therefore, have significant detrimental effects on the cell.
In contrast, the deletion of three nucleotides (a complete codon), would only result in the loss of a single amino acid in the produced protein, which may or may not significantly impact the function of the protein. Similarly, while a substitution could potentially alter the amino acid specified by the affected codon, this is less deleterious than a frameshift mutation.
