Changing our definition of life? Scientists rethink it?

Markus Ralser. In his research, he focused on cells that feed themselves and processes that grow wrong in the organism—the study intended on the origin of life.The group from the University of Cambridge studied a Glycolysis process that a process of beaks down sugar in a series of chemical reactions releasing energy that cells can use.

Living cells

There is some core chemical engine in every living cell. It is true in the simplest bacterium and the neuron of the human brain.The chemical engines drive metabolism to transform an energy source such as food into valuable parts and build up the cells.There are fossil microorganisms in rocks laid down 3.5 billion years ago, a mere billion years after Earth formed.

Key problem

The living organisms are extraordinarily complicated as the simplest bacterial cell has hundreds of genes and thousands of different molecules. The first metabolic process primarily produced in the biological process is carbon dioxide's fixation into organic materials.

Human metabolism

Every living thing takes in nutrients and uses them to build and repair its body. The digestive system can break down into simple chemicals that our bodies can use.One of the ways that cells can extract energy from nutrients is the citric acid cycle or Krebs cycle. The individual pathway in metabolism is intricate.

Living engine

Metabolic engines are not wholly inanimate the way Rocks are, nor are they fully living the way a bacterium.The biological machinery that built Earth's endless forms is most beautiful, no matter the definition.
