describe the organelles and structures a protein that is destined to leave the cell would interact with on its journey from synt
Umnica [9.8K]

Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.

The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).

Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.

Entamoeba histolytica can cause keratitis if it is introduced through an abrasion in the conjunctiva
inysia [295]

The given statement was False: A hookworm infestation frequently leads to anemia.

what is entamoeba histolytica ?

The parasitic anaerobic amoebozoan Entamoeba histolytica belongs to the genus Entamoeba. E. histolytica, which mostly infects humans and other primates and causes amoebiasis, is thought to infect between 35 and 50 million individuals globally. It is believed that E. histolytica infections cause more than 55,000 fatalities annually. Prior to the discovery that at least 90% of these illnesses were caused by a second species, E. dispar, it was believed that 10% of the world's population was affected. Although animals like dogs and cats can briefly contract the disease, it is not believed that they significantly contribute to its spread.

Histolysis literally translates to "dissolution and disintegration of biological tissues."

as the given statement was False, "A hookworm infestation commonly results in anaemia."

How do sexual reproduction produce new plants?
gavmur [86]

Sexual reproduction in flowering plants involves the production of male and female gametes, the transfer of the male gametes to the female ovules in a process called pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit.
