hi
why is the antibiotics non effective on viruses?
and is the co2 transport included in the syllabus or i should only know the bohr's effect?
CO2 transport is in the syllabus. They've asked about it in the past papers, I'm sure.
Antibiotics are ineffective against viruses because viruses are entirely different from other life forms in many different ways (there's even a debate about whether viruses are actually living things to begin with). Antibiotics (Greek 'anti-' against and 'bio' life) only affect proper life forms, such as bacteria and fungi, which have internal machinery, can move around, eat, reproduce, grow, etc. Viruses on the other hand are practically dead - they do not reproduce themselves and cannot metabolize - until and unless they come into contact with a living cell. When they infect the cell, they 'hijack' the internal machinery of that cell and use it to carry out their dirty work.
