How does an influenza virus cause symptoms of the flu to spread in the human body

An Influenza virus cause symptoms via different mechanisms such as:

•the inhibition of adrenocorticotropic hormone (ACTH)

•production of the huge amounts of proinflammatory cytokines and chemokines  produced from influenza-infected cells

Influenza virus invades the cells when the cleavage of the viral hemagglutinin protein occurs by some of the human proteases. It is cleaved by proteases found in the throat and lungs (that is why these tissues are inflammatory).

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
