There are dynamic relations between the living forms and their physical environment within the environment. The cyclic movements of chemical elements of biosphere between the organism and the ...

The Calvin-Benson cycle assimilates almost all the carbon in plants and is thus among the most important biochemical cycles for life on Earth. It is believed to be self-sufficient in that it ...

The regeneration of a signaling molecule, phosphatidylinositol 4,5 bisphosphate (PIP2), is not as simple as it was thought to be. Experimental work and mathematical modelling show that the decades-old ...

As travelers crossing time zones know all too well, humans and other organisms have circadian clocks, the biological machinery that controls daily cycles of gene expression and physiology. The ...

The Biogeochemical Cycles can be defined as the cyclic movement of chemical elements of biosphere between the organism and the environment. The term ‘Biogeochemical’ is a combination two words- Bio ...

Scientists at Penn State have discovered a previously unknown biochemical process that has led to their development of a fundamental new theory of the origin of life on Earth. The new theory improves ...

Class V myosins are two-headed, actin-based motors that use the free energy derived from ATP hydrolysis to produce a wide variety of directed cellular movements including the transport of melanosomes, ...

Few living things seem to have less in common than plants and animals, but that assumption is being increasingly challenged. Evolution, and the ways in which the kingdom of plants and the kingdom of ...
