    1.) Once in the respiratory tract, the flu virus targets cells based on specific glycoproteins on their surfaces. How does the virus gain entry into the target cell? Multiple Choice a.)Glycoproteins within the virus structure bind with glycoproteins on the membrane of the target cell and the virus squeezes through the glycoprotein into the cell. b.)Viruses are made up of lipids and can therefore diffuse through the membrane of target cells, gaining entry. c.)The H spikes of the influenza virus...

    5.To gain entry, spikes of the SARS-CoV-2 bind to angiotensin-converting enzyme 2 (ACE2) found in epithelial cells especially of the respiratory and oral passageways. As such, these cells are susceptible to infection by SARS-CoV-2. ACE2 is a protein consisting of multiple alpha-helices that is embedded in, and spans, the membrane. What is this type of protein called, and what structure do the alpha helices represent? 6.Following binding of spike proteins to ACE2, SARS-CoV-2 likely gains entry into the cell either...

    1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...
