They can and do secrete proteins
As an example of this they secreate protoglycans into the extra cellular space to form a 'slime.' The protens are made in the cell and secreted out of it.
A further example is where bacteria have been genetically modified to express insulin, which is a peptide hormone (and therefore a complex protein).
If bacteria (which are prokaryotes) were unable to excrete protein they would be unable to produce the insulin as it would quickly accumulate in the cell and cause its death.
What else can I help you with?
Can prokaryotes synthesize proteins?
Yes, prokaryotes can synthesize proteins. They have ribosomes and the necessary machinery to transcribe DNA into mRNA and then translate the mRNA into proteins. The process of protein synthesis in prokaryotes occurs in the cytoplasm.
What do prokaryotes and eukaryotes have in commmon?
DNA, proteins, plasma membrane
How is protein synthesis different in prokaryotes and eurkaryotes?
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
What is the method by which cells excrete proteins and how does it start in the endoplasmic reticulum?
Cells excrete proteins via exocytosis, where the proteins are pinched of the Golgi apparatus in vesicles. These vesicles then fuse with the cell surface membrane, thus expelling them from the cell. The entire process is Protein Traffiking, where it starts by being absorbs into the RER (rough endoplasmis reticulum) and is modified and activated during its journey to the outside of the cell. You're welcome.
Are cytoskeletons in prokaryotes?
Yes, some prokaryotes have cytoskeletons, although they are simpler in structure compared to eukaryotic cytoskeletons. Prokaryotic cytoskeletons are involved in maintaining cell shape, cell division, and intracellular transport. Examples of proteins that play a role in prokaryotic cytoskeletons include FtsZ, MreB, and Crescentin.
Can prokaryotes synthesize proteins?
Yes, prokaryotes can synthesize proteins. They have ribosomes and the necessary machinery to transcribe DNA into mRNA and then translate the mRNA into proteins. The process of protein synthesis in prokaryotes occurs in the cytoplasm.
Why ribosomes are attached to DNA in prokaryotes?
Ribosomes are not physically attached to DNA in prokaryotes; they are located in the cytoplasm where protein synthesis occurs. Ribosomes use the genetic information stored in DNA to assemble proteins. DNA in prokaryotes serves as the genetic blueprint for making proteins, and ribosomes read this information to build the proteins.
What do prokaryotes and eukaryotes have in commmon?
DNA, proteins, plasma membrane
Are cell structures common to both prokaryotes and eukaryotes on which proteins are made?
ribosomes
Why are red blood cells unable to synthasize proteins?
Mature blood cells do not have a nucleus. Without this genetic material, the cells are unable to synthesize proteins.
Are Golgi bodies in bacteria?
No. Prokaryotes have no need of protein modification and the ability to ship proteins out of the only cell they are.
How is protein synthesis different in prokaryotes and eurkaryotes?
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
What if you don't get enough proteins?
Your body will be weak and unable to function.
Prokaryotes have what structure necessary for protein synthesis?
Prokaryotes have ribosomes, which are the structures necessary for protein synthesis. Ribosomes are responsible for assembling amino acids into proteins based on the instructions provided by messenger RNA (mRNA).
Is humen ammoniatelic?
No, humans are unable to be considered an ammonotelic species. This is because we as humans are ureotelic, which means we excrete excess nitrogen as urea.
What are some problems that might arise if you are trying to produce a eukaryotic protein in a bacterium?
proteins are expressed differently in prokaryotes and eukaryotes
What would be a direct consequence of the disappearance of nitrogen fixing prokaryotes?
Organisms would not be able to get the nutrients they need to make proteins.
