Viruses lack the properties of living things:
1. They have no energy metabolism
2. They do not grow
3. They do not respond to stimuli
4. They do not reproduce independently- they have to replicate by invading living cells.
Explanation:
Genetic evolution is the meaning of biologic life, in that it is the why and how of it, as well as the stock of future biological existence. The genes that survive -- and in turn the organisms they make -- are the winners in the existence game. ... We owe our existence to this process, and our future depends on it.
The three main stages of cellular respiration (aerobic) would include Glycolysis, the Kreb's Cycle and the Electron Transport Chain. The Krebs Cycle takes Citric Acid which is a derivative of Pyruvic Acid and converts this through 4 cycles into Hydrogen, carbon dioxide and water in the Mitochondrial Matrix.
