Elis [28]3 years ago
4 0
The catecholamines is the stress related hormone that newborns needs in their bloodstream to avoid breathing problems. A catecholamine is a monoamine which is an organic compound that has a catechol and a side chain amine and is consequent from the amino acid tyrosine which is consequent from the dietary sources as well as fusion from phenylalanine. The catecholamine is water soluble and are 50 percent certain to plasma proteins in transmission.

Would the coupling of the processes shown below be found in a eukaryotic cell? explain why or why not. A diagram of transcriptio
nika2105 [10]

Polyribosomes are groups of ribosomes linearly arranged, associated with mRNA, and producing several copies of proteins. The coupling of processes shown in the image can not be found in eukaryotic cells.

<h3>What is a polyribosome?</h3>

A polyribosome is a group of single ribosomes associated with an mRNA molecule and producing simultaneous translation events of the same protein.

Polyribosomes can be found in both prokaryotic and eukaryotic cells. However, translation occurs at different moments and places in these cells.

⇒ In a prokaryotic cell

Polyribosomes can act before transcriptional termination occurs.

While transcription is still happening, ribosomes can produce many polypeptide copies.  

This is because

  • both transcription and translation occur in the cytoplasm simultaneously.

  • transcription and translation directions are 5' to 3'.

  • mRNA does not need to be modified after transcription.

⇒ In eukaryotic cells

Polyribosomes are found in the cytoplasm but only when

  • the transcription process is over,
  • the mRNA molecule is already modified and left the nucleus.

Since transcription occurs in the nucleus and translation in the cytoplasm, they can not be simultaneous.

According to this information, the coupling of processes shown in the image can not be found in eukaryotic cells.

Leto [7]

The human consist of four types of tissues: epithelial, muscular, and nevous.

The cell in the picture have a simple columnar epithelium being part of the ciliated tissues. The structures in the picture can be identified as:

A- Cilia (microvilli) (motile structural elements of the epithelial)

B- Epithelial columnar cells (epithelium) (keratinized squamous cell)

C- Connective tissue

D- Basement membrane
