2020年10月1日 · Intermediary metabolism is traditionally viewed as the large, highly integrated network of reactions that provides cells with metabolic energy, reducing power and biosynthetic intermediates. The elucidation of its major pathways and molecular mechanisms of energy transduction occupied some of the brightest scientific minds for almost two centuries.

2022年5月14日 · Glucose is taken up and metabolized by all cells to generate ATP by glycolysis and cellular respiration, and excess glucose is preferentially converted into glycogen rather than fats. Fructose is taken up only by liver cells, and excess …

Intermediary metabolism refers to the network of biochemical reactions within cells that process and convert nutrients into energy, building blocks for cellular structures, and other molecules necessary for cellular function.

指 物质代谢 过程中从开始物质A到最终产物X的中间各种反应。 在反应A→B→C→D→…→X中B→C、C→D等都是中间代谢。 中间代谢不是A→X的最短途径，多数是长途径迂回的反应系列。 由于细胞内的其他物质或各种条件对中间阶段的酶可产生作用，因此可能调节A的消耗或X的生成速度，同时也能转换成为另外的途径。 中间代谢在合成反应时需供给能量，而由异化反应释放出能量（如糖酵解生成ATP）等，所以物质代谢与能量代谢的联系和统一等是很重要的。 作为研究 …

2020年3月1日 · Intermediary metabolism refers to the sum of all intracellular chemical processes by which nutritive material is converted into cellular components. It includes anabolism (synthesis of macromolecules) and catabolism (breakdown of macromolecules).

Intermediary metabolism encompasses the compounds which are intermediates in the processes and the regulatory mechanism which maintain their homeostasis.

Intermediary metabolism is traditionally viewed as the large, highly integrated network of reactions that provides cells with metabolic energy, reducing power and biosynthetic intermediates. The elucidation of its major pathways and molecular mechanisms of energy transduction occupied some of the brightest scientific minds for almost two centuries.

Intermediary metabolism often referred to simply as metabolism, includes all steps between extracellular foodstuffs or nutrients and cellular components. These steps are catalyzed by enzymes within the cell and provide energy, reducing power and building blocks for maintaining cellular homeostasis or supporting cell growth.

By definition, “intermediary” means “between the most complex (structure) and the least complex”, whereas “metabolism” is a term derived from Greek meaning “a change or alteration.” In terms of the nutrient needs of vertebrate organisms, then, the building blocks of the three major energy substrates may be arranged (synthesized ...
