If you're talking about biological viruses, they dont actually need energy as they are mostly proteins and are inactive most of the time and become active only when they reach a host like a bacterium or any other cell. Its pure thermodynamics on how the virus attaches itself and injects DNA/RNA into the host. So there is no need for energy
Viruses do require energy however, they can only recieve it when they attach to a host cell.
yes
yes medical viruses does use energy
''Viruses do not have their own metabolism, and require a host cell to make new products.''
No. Viruses are not cells since they are not considered living. Scientists classify viruses as non-living because they require a host in order to reproduce, cannot move on their own, and do not expend energy in order to carry out life functions.
They get their nutrients fron their host.
a host cell
No, only a host cell to reproduce. (Viruses do not grow)
They both require a host cell to reproduce and they are both types of viruses
Viruses need a living host for reproduction. They, themselves, are not alive, so they must have a living host to provide the material to use for building duplicates, as well as for the energy to use in the production.
viruses dot need energy.
no it does not require energy.
The host
Viruses require a living organism to do anything - most especially to reproduce.
