Why was the cow insulin an effective substitute for the human insulin?

Biology

Ray Of Light [21]3 years ago

Pork and beef insulins are similar to human insulin, differing only in one or a few amino acids. However, even a slight difference is enough to elicit an allergic response in some people. To overcome this problem, researchers looked for ways to make insulin that would more closely resemble human insulin.

Answer:

The insulin of the cows is very similar to the human one, differing in the composition three amino acids.

Explanation:

Insulin is a peptide hormone, with a very complex structure. Its structure is formed by 51 amino acids distributed in two chains, linked by disulfide bonds between the cysteine amino acids. Cow insulin is different in three amino acids from human insulin. This difference is quite significant to produce allergy. To solve the problem, a process known as transpeptidization must be applied, which allows the substitution of the three different amino acids with the amino acids of the human insulin sequence.

<span>Desert rabbits are adapted to the warm climate because their large ears aid in the removal of heat due to the high heat of vaporization of water.
The rabbits that live in the desert are jackrabbits. An extensive network of blood vessels is present in the large ears of jack rabbits, due to this their large ears are used in cooling and radiating heat.</span>

Makovka662 [10]

Reflex action refers to the response to a stimulus, while reflex arch refers to the path taken by the reflex action.

<h3>What is the nervous system? </h3>

1. Low oxygen levels are detected by sensory receptors in the arteries.

2. An impulse is produced by sensory neurons.

3. Certain parts of the brain get an impulse from the central nervous system.

4. Motor neurons carry messages from the brain.

5. Isabel's respiration becomes more rapid.

Reflex actions are immediate, reflexive reactions to stimuli that limit bodily harm.

Therefore, it travels to the brain via the central nervous system and sends impulses via Isabel's motor neurons, which aid to speed up her breathing.

g The Electron Transport Complex (ETC) consists of four proteins. How many of these proteins directly contribute to the proton g
vladimir2022 [97]

Answer:

Three proteins directly contribute to the proton gradient by moving protons across the membrane

Explanation:

The Electron transport chain is a group of proteins and molecules incrusted in the internal mitochondrial membrane and organized into four complexes, I, II, III, and IV. These complexes contain the electron transporters and the enzymes necessary to catalyze the electron transference from one complex to the other. Complex I contains the flavine mononucleotide -FMN- that receives electrons from the NADH. The coenzyme Q, located in the lipidic interior of the membrane, conducts electrons from complex I and II to complex III. The complex III contains cytochrome b, from where electrons go to cytochrome c, which is a peripheric membrane protein. Electrons travel from cytochrome c to cytochromes a and a3, located in the complex IV. Finally, they go back to the matrix, where they combine to H+ ions and oxygen, to form the water molecule. As electrons are transported through the chain, protons are bombed through three proteinic complexes from the matrix to the intermembrane space. These are complexes I, III and IV.

In the family tree below, people with the recessive trait of attached earlobes
madam [21]

Answer:

C. It is a male with atleast one dominant allele

Explanation:

In the given pedigree, the two normal parents of the generation I have one daughter with the attached earlobe. Since the trait is recessive, the daughter should be homozygous recessive to express the trait. The genotype of the daughter (shaded circle in generation II) is "aa". To have a daughter with "aa" genotype, both the parents should have one copy of "a" allele. So, the genotype of both parents is "Aa".

In generation II, individual A is non-shaded square. Squares represent males in a pedigree. Since its not shaded, it does not have attached earlobe. Both the parents are heterozygous dominant for attached earlobes (Aa x Aa = 1/4 AA : 1/2 Aa : 1/4 aa). The genotype of this individual may be AA or Aa.
