Respiration,bolism (Figure 3.1)., The latter transfers some of the chemical, potential energy in food to high-energy, phosphate bonds (~P) usually in adenosine triphosphate (ATP) molecules, and these, or at least the energy that they store, are then used to power mechanical work (e.g. muscular contraction), che

序曲

Excretion,s, are broken down further in a process known as oxidative deamination:.The keto acids can be used in other pathways of intermediary metabolism. However, because of its low pH, ammonia is highly toxic to tissues and must be removed rapidly from the body or be rendered harmless. These processes are r

Growth,n increases in the sizes of whole organisms with time. Size, of course, can be expressed either in linear dimensions, mass or potential energy and this in itself has presented one of the major difficulties for formulating a precise definition — which is the most appropriate unit? Some consideration

Integration,or, at least, partial isolation. However, organisms interact with their abiotic environment and each other as whole, functional units and so in this final chapter we consider how the separate pieces of the metabolic jig-saw fit together.

Monotonous

Acquisition,Invertebrates, like all other heterotrophic organisms, require food to supply the raw materials necessary for building the body and to supply energy to power movement and metabolism. Whatever its form or origin, food must therefore supply the following:

Reproduction,dependent on reproductive success. Hence the process of reproduction is likely to bear the stamp of natural selection in a more obvious way than any other aspect of the functional biology of organisms.
