CONCLUDING STATEMENTS (Bioenergetics)
There are two aspects of bioenergetics that we want to emphasize at the end of this article. These are the dependence of life on photosynthesis and the diversity of energy interconversions in living...

ATP powers most of the endergonic processes in cells. How the potential energy of the phosphoanhydride bond of ATP may be used to drive otherwise unfavorable reactions (Fig. 11) is discussed in this...

In animal, yeast, and fungal cells, DNA is present in two organelles, the nucleus and the mitochondria. In plant and algal cells, DNA is present in plastids (of which chloro-plasts are one example) as...

From a purely thermodynamic standpoint, life is an improbable event. Consider, for example, the complex structures of organisms, not only at the macroscopic level, but also at the microscopic and...

Metabolism may be defined as the total of all the chemical reactions that occur in organisms. Green plants can synthesize all the thousands of compounds they contain from carbon dioxide, water, and...
