An insect bite on the face produces a break in the skin which introduces the normal skin flora (usually Staphylococcus and Streptococcus) to the sterile subcutaneous tissue causing inflammation. The inflammation of the subcutaneous tissue is called cellulitis. Since the infection is in the face, then it can travel from the infected site to the meninges through the cavernous sinuses and cause bacterial meningitis.

Where does the first stage of cellular respiration occur?

Anestetic [448]

The first stage of cellular respiration is glycolysis. It takes place in the cytosol of the cytoplasm. The word glycolysis means “glucose splitting,” which is exactly what happens in this stage. Enzymes split a molecule of glucose into two molecules of pyruvate (also known as pyruvic acid). This occurs in several steps, as shown in Figure below.
