imagine a cell-surface receptor protein is being newly synthesized. How can it get into the membrane that it will ultimately be
motikmotik

Answer:

the steps for a new receptor synthesis:

Explanation:

Do not forget the steps vary from an eukarityc cell to prokarityc one.  

IN AN EUKARYOTIC CELL:

1- Transcription: in the nucleus, mRNA is synthesized from the DNA sequence that codifies the protein. Exons are spliced if needed by spliceosomes.  

2- From nucleus into cytoplasm: mRNA goes through nuclear membrane into the cytoplasm were ribosomes, substrates for protein synthesis and other organelles are.

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)  

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- (The mRNA has a signal that is recognized by the rough endoplasmic reticulum) The peptide goes into this reticulum (RER) and then into Golgi apparatus. (more chemical modifications are made if needed). By this moment the protein has an inserted portion in a lipid membrane.

6- The protein is transported in a vessel that finally fusions with cytoplasmic membrane and the receptor is in destiny. Hydrophobic aminoacid sequences are inserted in membrane.

IN A PROKARYTIC CELL:

1- Transcription (no splicing is needed, there are not exons)

2- There are not nucleus and cytoplasm divided (no transport)

3- Ribosomes recognize a signal in mRNA and start reading the genetic code, three consecutive nucleotides at a time and adjust the correspondent tRNAs (tRNAs carry the aminoacids)

4- Peptide bonds are formed between consecutives aminoacids, and a polypeptide is build up according to the mRNA sequence.

5- The mRNA has a signal that is guides the growing protein to cellular membrane. Hydrophobic aminoacid sequences are inserted in membrane.

What are the long-termand short-term<br> effects of stress on the body, brain, andbehavior?
IgorLugansk [536]

Answer:

The short term effects of stress include pain, nausea, change in appetite, heartburn, constipation, and in some cases, diarrhea.

Long term effect of stress on the body and behavior include changes in one's eating habits and chronic pain. Another long-term effect of stress is acid flux.

Asides having negative effect on the body and behavior, stress can also have some negative effect on the brain such as increasing the risk of developing mental illness, killing of the cells in the brain, brain shrink, and it can hurt one's memory.

Millions of years ago, the Indian plate began pushing gradually towards the Eurasian plate. The land above started rising in var
jasenka [17]

Answer:

D) Folded mountain with jagged, rough edges

Explanation:

The incident which happened some fifty million years ago was the collision of the Indian plates and the Eurasian plates thus giving rise to the folded mountains that are characteristic of the Himalayas. Subduction was not possible when these two plates collided because they had the same density.

So, the force with which the two plates collided resulted in the formation of folded mountains that rose upward. The peaks of these mountains were jagged, rough, and uneven.
