Answer:
A. The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
Explanation:
According to the given information in this question, Lactobacillus acidophilus is a bacterium species that uses the lactic acid fermentation when there is no oxygen in its cell i.e. under anaerobic conditions. This means that it converts glucose to lactic acid during this anaerobic respiration process.
However, if the lactic acid fermentation pathway were blocked under an anaerobic condition, this means that it will be no longer be able to perform respiration and hence stop production of ATP. This is because the bacteria will no longer regenerate the NAD+ (electron acceptor) needed for glycolysis, so it would stop producing ATP. Note that, all living organisms, whether aerobic or anaerobic, undergo GLYCOLYSIS, which is the first stage of cellular respiration.
Answer:
The inducer will combines with the repressor and inactivates the pathway.
Explanation:
Inducer is a term in Molecular Biology, which represent a molecule or substance that has the capability to activate the transcription of a gene, where by it joins with and then inactivates a genetic repressor.
In other words, the inducer binds with the repressor in order to prevent the RNA polymerase to combine to the DNA, and chemically produce mRNA, this is done by repressor proteins combining with the DNA strand.
Inducer specifically makes repressor to change shapes, which will make it not combine with the DNA, and therefore, allow formation of transcription, such that expression of gene will eventually occur.

Answer:
DNA polymerase makes a molecule of RNA from a DNA template
Explanation:
DNA polymerase is an enzyme involved in the process of DNA replication. DNA replication replicates or synthesizes a new DNA replicate from the parental DNA.
The enzymes mentioned in the question perform a specified function which is matched with their description except for DNA polymerase as this enzyme is responsible for adding nucleotides to the synthesizing strand from the template strand f DNA.
Thus, the selected option is correct.
