To answer these questions, we need to understand the concepts related to protein structure and gene expression.

1. What happens if a toxic substance interferes with monomers in the tertiary or quaternary structures?
To find the answer, we need to know the effects of a toxic substance on the structure of proteins. The tertiary and quaternary structures refer to the higher levels of protein structure where interactions between multiple protein subunits occur. Denaturation of these structures can lead to loss of protein function. So, if a toxic substance interferes with the monomers of a protein and denatures the tertiary or quaternary structures, the molecular reaction will be delayed or inhibited due to denaturation of the enzyme. Therefore, the correct answer is option a.

2. What molecule is ultimately responsible for putting together a particular enzyme?
To answer this question, we need to identify the cellular component involved in protein synthesis. Ribosomes are responsible for translating the genetic information encoded in mRNA molecules into a specific sequence of amino acids, thereby assembling proteins. So, the molecule ultimately responsible for putting together a particular enzyme is ribosomes. Therefore, the correct answer is option b.

3. If a gene's instruction set (in DNA) were changed by a mutation, then what do you think would happen to the enzyme it creates?
To answer this question, we need to understand the impact of mutations on gene expression. A mutation refers to a change or mistake in the DNA code. The DNA code contains instructions for synthesizing proteins, including enzymes. If the instruction set of a gene is changed by a mutation, it can result in alterations in the amino acid sequence of the enzyme. This, in turn, can affect the structure and functionality of the enzyme. Therefore, if a gene's instruction set is changed by a mutation, the enzyme it creates would likely be defective. Hence, the correct answer is option a.
