Question

What are antibiotics? Give 2
examples.
why are antibiotics ineffective
against viral diseases?​

Answer 1

Answer:

1.The main types of antibiotics include:

• Penicillins - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.
• Cephalosporins - for example, cefaclor, cefadroxil and cefalexin.
• Tetracyclines - for example, tetracycline, doxycycline and lymecycline.
• Aminoglycosides - for example, gentamicin and tobramycin.

2.Viruses can't reproduce on their own, like bacteria do, instead they attach themselves to healthy cells and reprogram those cells to make new viruses. It is because of all of these differences that antibiotics don't work on viruses.

Answer 2

The mitochondrial intermembrane space is the space between the outer membrane and the inner membrane. It is also known as perimitochondrial space. Because the outer membrane is freely permeable to small molecules, the concentrations of small molecules, such as ions and sugars, in the intermembrane space is the same as in the cytosol.[17] However, large proteins must have a specific signaling sequence to be transported across the outer membrane, so the protein composition of this space is different from the protein composition of the cytosol. One protein that is localized to the intermembrane space in this way is cytochrome c.[28
