the organic processes ( in a cell or organism) that are necessary for life

the marked and rapid transformation of a larva into an adult that occurs in some animals

The act or process, by which living tissues or cells take up and convert into their own proper substance the nutritive material brought to them by the blood, or by which they transform their cell protoplasm into simpler substances, which are fitted either for excretion or for some special purpose, as in the manufacture of the digestive ferments. Hence, metabolism may be either constructive ( anabolism), or destructive ( katabolism).

The series of chemical changes which take place in an organism, by means of which food is manufactured and utilized and waste materials are eliminated.

The sum of chemical changes that occur within the tissues of an organism consisting of anabolism ( BIOSYNTHESIS) and catabolism; the buildup and breakdown of molecules for utilization by the body.

Tissue- change, the sum of the chemical changes whereby the function of nutrition is effected; it consists of anabolism, or the constructive or assimilative changes, and catabolism, or the destructive or retrograde changes.

Progressive tissue change.

The process by which, on the one hand, food is built up into living material, and, on the other, living matter is broken up and decomposed.

The chemical change, constructive and destructive, occurring in living organisms.

2. The metabolism in pellagra shows certain definite changes from the normal, which point to decreased gastric secretion and increased intestinal putrefaction. – The Vitamine Manual by Walter H. Eddy

Together they form the directorate of sugar metabolism. – The Glands Regulating Personality by Louis Berman, M.D.

Just as soon as the diet is made a little more rigid and the sugar metabolism improves, then exercise can be taken and will benefit the patient. – Psychotherapy by James J. Walsh

But, as is evident from a glance at the membership of the growth directorate, and comparing it with the directorate of sugar metabolism, there are some members who are present on both boards. – The Glands Regulating Personality by Louis Berman, M.D.

Despite all the laws of physics, their body temperature had remained constant after it had reached seventy- four, showing that some form of very slow metabolism was going on. – The Black Star Passes by John W Campbell

They are the waste products of metabolism. – How and When to Be Your Own Doctor by Dr. Isabelle A. Moser with Steve Solomon

Rachitis or rickets is a pathological condition in some way connected with a protracted disturbance of digestion which in turn leads to faulty calcium metabolism. – Food Poisoning by Edwin Oakes Jordan

A cure consists in changing the manner of living to such a rational standard that full resistance and a balanced metabolism is established. – How and When to Be Your Own Doctor by Dr. Isabelle A. Moser with Steve Solomon

But then what kind of a fancy- pants metabolism could you expect out of an organism that fed on nothing but Lake Michigan water, right out of the reservoir? – The Water Eater by Win Marks

The only paper that we have seen that suggests another function than antiscorbutic power for this vitamine is the one by McCollum and Parsons in which they suggest that even in animals where scurvy does not exist, the presence of this factor may be necessary to normal metabolism. – The Vitamine Manual by Walter H. Eddy

It seemed reluctant to step up general metabolism. – Has Anyone Here Seen Kelly? by Bryce Walton

In the male the parasite requires similar substances, and its demand on the blood of the host stimulates the secretion of such substances, so that the whole metabolism is altered and assimilated to that of the female. – Hormones and Heredity by J. T. Cunningham

It is very probable that in the early stages of development the metabolism of the body would be considerably different from that of the adult stage, and the same combination of hormones would not be present. – Hormones and Heredity by J. T. Cunningham

Our metabolism was designed around them. – The Pirates of Ersatz by Murray Leinster

Her only regret was that she was not able to give to each her personal time and attention, and establish herself on a footing with her patrons where she might learn from their own lips the secrets of their metabolism. – Outside Inn by Ethel M. Kelley

Every day science is getting closer to the control of metabolism. – The Dream Doctor by Arthur B. Reeve

An osmotic production is the arena of complicated chemical phenomena which produce a veritable metabolism. – The Mechanism of Life by Stéphane Leduc

For scholastic philosophers unity of life in the living thing, involving the fact of memory in animals, is explained by the perfectly intelligible and will- grounded teaching that there is in each individual living thing a formative and vital principle which is substantial, a forma substantialis, which unites, in the abiding self- identical unity of a complete individual composite substance, the material principle of the corporeal substances which thus go, in the incessant process of substantial change known as metabolism, to form partially, and to support the substantial continuity of, the living individual. – Ontology or the Theory of Being by Peter Coffey
