B. They are able to produce their own food.
The incorporation of valinomycin, a neutral antibiotic, into a polyvinyl chloride membrane allows for the manufacture of an ion-selective electrode that is highly selective for potassium.
<h3>How Valinomycin Ionophores Enter and Transport K+ across Model Lipid Bilayer Membranes?</h3>
- A biomimetic lipid membrane attached to the surface of the gold electrode contained the cyclic peptide valinomycin.
- The ionophore characteristics of the peptide were investigated using electrochemical impedance spectroscopy, and the conformation and orientation of the antibiotic valinomycin within the membrane were identified using polarization modulation infrared reflection absorption spectroscopy.
- By forming a complex with potassium ions and an ion pair with a counter anion, valinomycin transports ions across the membrane, and the combination of these two techniques revealed novel information about the ionophore mechanism.
- The ion pair is located inside the hydrophobic portion of the membrane and makes a little angle of around 22° with the surface normal.

Answer:
The statement that is false is <u>metabolism is regulated largely by the nervous system.</u>
Explanation:
The metabolism reactions are controlled by the enzymes specific for each metabolic reactions. After a signal is generated, specific enzymes that detect the signal starts up the metabolic reactions.
When there is a need to stop a certain metabolic reaction, then the mechanism of feedback inhibition is used which stops the enzyme from carrying out any further reactions. Hence, the statement that metabolism is regulated largely by the nervous system is false.
