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 via fusion of its envelope with the cell membrane, or via endocytosis. If the latter, the virus must escape the endosome before fusion with the cellular lysosome. Once inside the cytoplasm, the virus unpackages and its positive stranded RNA genome is released.
This type of protein is called membrane spanning proteins.
Alpha helix represent the secondary structure of proteins.
6. Endocytosis is the process of engulfing the extracellular components by the invagination of cellular membrane.
Lysosome is the acidic compartment of cells which contain many hydrolytic enzymes .it becomes fused with the endosome or late endosome which is produced when something has been captured by cell either by phagocytosis or cell has to digest some protein intracellularly.
Then these late ENDOSOME fused with lysosomes and digest the particles which is present inside the endosome.
RNA is a nucleic acid which can produce proteins.
Thank you

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...
1-1. The SARS-CoV-2 is an enveloped virus, meaning it is surrounded by a bilayer of membrane that it acquires as it exits the host cell. a. What is the host membrane bilayer made of? b. What is the other main macromolecule that comprises the “fluid mosaic” model of a cell membrane? 1-2. 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...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
