The nervous system is divided into several parts, and in this case, the answer is Sympathetic Nervous System.
SNS is responsible of the regulation of homeostatic organic mechanisms; such as fighting and running behaviors, heart rate, dilation of bronchi and pupils, and adrenal glands stimulation.

Answer:
The correct answer will be option-C.
Explanation:
The production of ATP from ADP and Pi (inorganic phosphate) catalyzed by an enzyme known as ATP synthase.
ATP synthase is made up of two main regions called F₀ and F₁ in which F₀ is embedded in the membrane and acts as a pump through which proton flux takes place. The F₁ unit is the rotating unit of the ATP synthase which rotates due to energy provides by the protons during proton flux.
When proton moves through F₀ unit down their concentration gradient, it provides energy to the F₁ subunits which bind ADP and inorganic phosphate to release ATP.
Thus, Option-C is the correct answer.
A bacterium has a faulty lac operon in which there is a structural defect in the operator. In this bacterium there is a structural problem with a segment of DNA that binds a repressor.
- A protein known as a repressor binds to an operator site. The operator in this instance (and numerous others) is a section of DNA that lies just downstream of the RNA polymerase binding site or overlaps with it (promoter). In other words, it lies between the operon's promoter and its genes.
- The repressor protein inhibits the synthesis of messenger RNA by attaching to the promoter region of the gene(s) (mRNA). The control of gene expression in cells requires repressor proteins.
- Thus, by physically impeding the RNA polymerase's ability to operate, these repressor proteins stop the gene from being transcribed.
