- A typical human hepatocyte (liver cell), a widely studied eukaryotic cell, has a diameter of about 20 μm. Calculate the volume of both a prokaryotic and a eukaryotic cell. To appreciate the magnitude of the size difference between the two cell types, estimate how many bacterial cells would fit inside the liver cell. (Hint: Use the expression V = πr 2h for the volume of a cylinder and V = (4/3)π r 3 .A bacteri was isolated from a Hyper alkaline spring. It was observed to be embedded in its cell membrane. Describe the proteins properties if it can act as anchorage of prokaryotic cytoskeletal elements.The dimensions of prokaryotic ribosomes are approximately 14 nm by 20 nm. If ribosomes occupy 20% of the volume of a bacterial cell, calculate how many ribosomes are in a typical cell as E. coli. Assume that the shape of a ribosome is approximately that of a cylinder.
- The true nucleus is generally absent in E.coli and other prokaryotes.Comment.How many E. coli cells can fit in the volume occupied by a single eukaryotic cell of a round shape with the diameter of 50um? Assume that a E. coli cell is a cylinder with the diameter of 0.5um and the height of 2um. In this problem am I suppose to already have prior knowledge of the volume of eukaryotic cell and prior knowlege of volume of E coliSterile normal saline is used in most surgical procedures as an irrigation solution. During certain surgical procedures, such as those for malignancy, the surgeon may request that sterile water be used for irrigation instead of saline following excision of the cancerous mass. What reaction will occur between the eukaryotic cells of the body and the water?
- In the eukaryotic cell, the members of the endomembrane system work together to synthesize protein products used for excretion out of the cell (e.g. insulin, milk etc.) and for use within the cell (e.g. lysosomes etc.). Explain in detail the correct sequence of steps and processes involved. 200 word minimum.Enumerate four ultrastructures common to all cells whether prokaryotic or eukaryotic. What particular significance can you associate with the presence of these common ultrastructures in all cells?Eukaryotic cells are almost always larger than prokaryotic cell. What structure might allow for their larger size.
