Protein are digested and transported by fellow proteins. Give vivid example to support the statement
julsineya [31]

Answer:

Proteins are digested in the body when ingested food from a protein source, is broken down in the stomach by enzymes like Chymotrypsin, trypsin which are both proteins, their common goal is to convert protein into a more simple form or simplest form ( Amino acids). This enzyme (Chymotrypsin and trypsin) are Proteins and they act as biological catalysts that are responsible for breaking proteins down.

An example of how Proteins are transported by fellow proteins is the case of Ferritin. Ferritin is an essential protein in the cell of the body that regulates the amount of iron available to the body. This is important for the hemoglobin in red blood cells.

What is expressed when both alleles for a gene are equally expressed as in human blood type
alexandr402 [8]

As both the genes get equally expressed in the human blood group genes, both the proteins or characters expressed by those genes get prominent in the phenotype of the organism.

<h3><u>Explanation:</u></h3>

In case of human blood type, there are co dominance between the genes coding for A blood group and B blood group. Absence of both of them produce the O blood group and presence of both of them produce the AB blood group.

The gene for A blood group codes for enzyme α-1,3-N-acetylgalactosamine transferase which attaches the N Acetylgalactosamine to surface of RBCs which are actually the A antigens.

The gene for B blood group codes for  α-1,3-galactosyl transferase which attaches galactose to surface of RBCs which are actually B antigens.

Presence of both of these genes make both N Acetylgalactosamine and galactose to be present on RBC membrane. This is why co dominance occurs in case of AB blood group persons.
