Question

4. Determine the time of protein synthesis from 20 amino acids in Escherichia coli cells

Answer 1

Step-by-step explanation:

Protein synthesis, or translation, is the process by which cells synthesize proteins from amino acids using the information stored in their DNA. In Escherichia coli cells, protein synthesis occurs in the ribosomes, which are small, specialized organelles that translate the genetic code in mRNA into a sequence of amino acids.

The time it takes to synthesize a protein from 20 amino acids will depend on a number of factors, including the size and complexity of the protein, the efficiency of the ribosomes, and the availability of the necessary amino acids and other resources. In general, the rate of protein synthesis in E. coli cells is relatively fast, with some ribosomes able to synthesize up to 20 amino acids per second. This means that it could potentially take only a few seconds to synthesize a small protein consisting of 20 amino acids. However, it is important to note that this is just a rough estimate and the actual time may vary depending on the specific circumstances.

Answer 2

E. coli can synthesize all of the amino acids from inorganic compounds and glucose but it is also capable of transporting intact amino acids into the cell from the extracellular environment.
