The faculty of capacity of the human mind by which it is distinguished from the intelligence of the inferior animals; the higher as distinguished from the lower cognitive faculties, sense, imagination, and memory, and in contrast to the feelings and desires. Reason comprises conception, judgment, reasoning, and the intuitional faculty. Specifically, it is the intuitional faculty, or the faculty of first truths, as distinguished from the understanding, which is called the discursive or ratiocinative faculty. We have no other faculties of perceiving or knowing anything divine or human, but by our five senses and our reason. (P. Browne) In common and popular discourse, reason denotes that power by which we distinguish truth from falsehood, and right from wrong, and by which we are enabled to combine means for the attainment of particular ends]]. (Stewart) Reason is used sometimes to express the whole of those powers which elevate man above the brutes, and constitute his rational nature, more especially, perhaps, his intellectual powers; sometimes to express the power of deduction or argumentation. (Stewart) By the pure reason I mean the power by which we become possessed of principles. (Coleridge) The sense perceives; the understanding, in its own peculiar operation, conceives; the reason, or rationalized understanding, comprehends. (Coleridge)

I was promised, on a time, To have reason for my rhyme. (Spenser) But law in a free nation hath been ever public reason; the enacted reason of a parliament, which he denying to enact, denies to govern us by that which ought to be our law; interposing his own private reason, which to us is no law. (milton) The most probable way of bringing France to reason would be by the making an attempt on the spanish west Indies. (Addison)

4. (Science: mathematics) ratio; proportion. By reason of, by means of; on account of; because of. Spain is thin sown of people, partly by reason of the sterility of the soil. . In reason, In all reason, in justice; with rational ground; in a right view. When anything is proved by as good arguments as a thing of that kind is capable of, we ought not, in reason, to doubt of its existence. (Tillotson) It is reason, it is reasonable; it is right. Yet it were great reason, that those that have children should have greatest care of future times. (bacon)

Re: Why is ATP rather than GTP, CTP or TTP the energy currency?

... that links to similar ΔG°' values. However, actual ΔG in the cell will depend on the ratio of tri- and di-phosphorylated forms. Surely the only reason hydrolysis of ATP releases free energy is because the reaction is far from equilibrium (otherwise no energy would be released, and there would ...
