Graph attached

Answer:

b. Less energy is needed to start reaction B.

Explanation:

The graph shows two different reactions and the energy required over time

a. More energy is released by the original reaction. - this is false, more energy is required for the original reaction to proceed

b. Less energy is needed to start reaction B. - this is true, the peak of the curve is lower showing less energy is required

c. The original reaction is catalyzed. - this is false, likely reaction B is catalyzed

d. Reaction B occurs at a slower rate.- false, they occur at the same rate.

Why does synthetically produced RNase refold incorrectly if the reducing agent is removed before urea removal?

olya-2409 [2.1K]

<h2>Disulfide bonds interaction </h2>

Explanation:

The high concentration of urea causes unfolding of protein and thus results in loss of function of a protein. The urea interacts with the protein and prevents the folding of a protein.
During oxidation, the disulfide bonds that are required for proper functioning and stabilization of protein are formed, while in the presence of urea, the disulfide bonds are not positioned correctly. The protein oxidation results in covalent modification of a protein that results in the change of physical and chemical properties of a protein.
The change of physical and chemical properties of protein after oxidation and in the presence of urea cannot be modified even after the removal of urea. Thus, protein does not fold properly.
Hence the right answer is "disulfide bonds are not positioned correctly rather than week bonding interaction"

Sickle-cell anemia is an example of an inherited disease. Individuals with this disorder have misshapen (sickle shaped) red bloo

Makovka662 [10]

Answer:

See the eplanation below, please.

Explanation:

In sickle cell anemia, hemoglobin has the form of rigid bars inside the red blood cells, causing them to adopt sickle shapes being not very flexible. These cells can block blood vessels, stopping the flow, causing oxygen to not reach the tissues.

The cause of this anemia is due to a genetic mutation (there is a substitution of thymine for adenine in the beta globin gene, located on chromosome 11), generating Hemoglobin S with a decrease in oxygen binding.

Goryan [66]

Answer:

Explanation:

The stinger should be scrapped away from the skin. The stinger of honey which is located in the abdomen of the bee produces venom via the venom sac. A sting from a bee introduces this stinger and the whole abdomen into the skin. This causes allergy and must be removed
