The main function of the virion is to deliver its DNA or RNA genome into the host cell so that the genome can be expressed (transcribed and translated) by the host cell. The viral genome, often with associated basic proteins, is packaged inside a symmetric protein capsid.
Explanation:
what is a virus A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898, more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology.
Cellular respiration is defined as a ATP generating process in which organic molecule is oxidized and inorganic molecule is final electron acceptor
Pain experienced in leg muscles is the result of formation of lactic acid in muscle cells
Under low oxygen, NADH cannot be reoxidized to NAD+ but NAD+ is required as an electron acceptor to continue glycolysis
In lactic acid fermentation pyruvate is the final electron acceptor and converted in lactate
Reaction catalyzed by lactate dehydrogenase
The pain in her chest is caused from the lack of oxygen she received while running so her chest starts to heavily breathe so that the lungs can receive as much oxygen possible
