| reaction quotient | <chemistry> A constant represented by the symbol Q which is defined as the product of the concentrations of the products, each raised to the power that corresponds to its coefficient in the balanced equation, divided by the product of the concentrations of reactants, each raised to the power that corresponds to its coefficient in the balanced equation (see the equation in the equations page). at equilibrium conditions Q=K, the equilibrium constant.

| Meyerhof oxidation quotient | <biochemistry> An index for the effect of oxygen on glycolysis and on fermentation (i.e., on the Pasteur effect); equal to the rate of anaerobic fermentation minus the rate of aerobic respiration divided by the rate of oxygen uptake. (21 Jun 2000) |

| P/O quotient | A measure of oxidative phosphorylation; the ratio of phosphate radicals esterified (forming adenosine 5'-triphosphate from adenosine 5'-diphosphate) to atoms of oxygen consumed by mitochondria; normally, the ratio is 3 (starting from NADH). Synonym: P/O quotient. (05 Mar 2000) |
| protein quotient | The number obtained by dividing the quantity of globulin of the blood plasma by the quantity of albumin. Respiratory quotient (R.Q.), the steady state ratio of carbon dioxide produced by tissue metabolism to oxygen consumed in the same metabolism; for the whole body, normally about 0.82 under basal conditions; in the steady state, the respiratory quotient is equal to the respiratory exchange ratio. Synonym: respiratory coefficient. (05 Mar 2000) |

| quotient | 1. <mathematics> The number resulting from the division of one number by another, and showing how often a less number is contained in a greater; thus, the quotient of twelve divided by four is three. 2. The result of any process inverse to multiplication. See the Note under Multiplication. Origin: F, fr. L. Quoties how often, how many times, fr. Quot how many. See Quota.

| intelligence quotient | <psychology> The psychologist's index of measured intelligence as one part of a two-part determination of intelligence, the other part being an index of adaptive behaviour and including such criteria as school grades or work performance. IQ is a score, or similar quantitative index, used to denote a person's standing relative to his age peers on a test of general ability, ordinarily expressed as a ratio between the person's score on a given test and the score which the average individual of comparable age attained on the same test, the ratio being computed by the psychologist or determined from a table of age norms, such as the various Wechsler intelligence scales.
