By decarboxylating arginine, Escherichia coli's severe acid resistance response is arginine-dependent.
A proton is actually exported with each turnover of the membrane antiporter AdiC, which catalyzes the decarboxylation product agmatine's efflux together with arginine influx.
<h3>Extreme acid resistance is facilitated by a bacterial arginine-agmatine exchange transporter.</h3>
- We produced and purified the transport protein using the adiC coding sequence under the control of a tetracycline promoter in an E. coli vector, with a yield of roughly 10 mg/liter bacterial culture.
- In detergent micelles and lipid membranes, the protein is a homodimer, according to tests using the cross-linking of glutaraldehyde.
- In liposome form, purified AdiC exchanges arginine and agmatine in a closely linked, electrogenic manner.
- The dissociation constant for Arg, as calculated by isothermal titration calorimetry, is in the same range as the K(m) value obtained through kinetic analysis, which is around 80 microm.

<span>Assists in the accommodation of light from the external environment that penetrates thru our pupil and proceeds in our lens.
Evolutionarily, the eye structure was designed to be at the head specfically superior to the nose, posterior to the skill and distal to the brain and is anteriorly plastered to avoid environmental threats like predators, natural disasters and etc. This way in a functionalist view, the eye has a wider range in getting information from one's environment especially in humans since the eyes in people are the most efficient and powerful sensory organs than the others. In a structural view, the eyes are build in two not only to be able to see one's environment and maximise it but also because the eyes have binocular disparity this means that the eyes will be able to locate an object more cearly and that when one eye is dysfunctional the other can assist the visual imagery of the individual.<span>

Answer:Isotonic: The solutions being compared have equal concentration of solutes. Hypertonic: The solution with the higher concentration of solutes. Hypotonic: The solution with the lower concentration of solutes.
