If antibodies to fibronectin are exposed to an embryo through which neural crest cells are migrating

Biology
1 answer:
lidiya [134]3 years ago

Answer:

Neural crest cell movements are inhibited.

Explanation:

Neural crest cells may be defined as the temporary group of cells that are unique for the chordata group. These cells arise from the embryonic ectoderm and give rise to future melanocytes.

Antibodies to fibronectin association is helpful to study the signalling factors. If these anitodies to fibronectin is shown in the embryonical stage. The neural crest migration is inhibited by its exposure to fibronectin and this might hinder the embryonic development.

Thus, the answer is neural crest cell movements are inhibited.

What are molecules that help make the cell make its proteins correctly
gavmur [86]

Answer:

To build proteins, cells use a complex assembly of molecules called a ribosome. The ribosome assembles amino acids into the proper order and links them together via peptide bonds.

Hope this helps :)

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?
Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the  active site.

On binding, it disrupts the  normal hydrogen bond and hydrophobic   interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and   ACTIVE SITE of the  enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit  for binding with the substrate, therefore  the efficiency  is reduced. No substrate-enzyme complex, and hence no substrate-product  complex for the release of  products, this brings down the turnover rate and eventually

<u>the rate of reaction of the enzyme</u>

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,
