The new hydrophilic amino acid would not form the same interactions with hydrophobic R groups. As a consequence, protein's 3D structure would likely be affected.
Different types of amino acids have different properties and thus form different interactions. For example, hydrophobic amino acids (water-repelent) such as alanine, valine, leucine, isoleucine, proline, phenylalanine, cysteine and methionine. participate in van der Waals type of interactions. They often form the hydrophobic core of the protein which doesn’t interact with water surrounding.
On the other hand, hydrophilic amino acids (arginine, asparagine, glutamine, aspartat..) are polar, can dissolve in the water and can join the hydrogen bond network.
Answer:
The correct answer will be option-C.
Explanation:
The production of ATP from ADP and Pi (inorganic phosphate) catalyzed by an enzyme known as ATP synthase.
ATP synthase is made up of two main regions called F₀ and F₁ in which F₀ is embedded in the membrane and acts as a pump through which proton flux takes place. The F₁ unit is the rotating unit of the ATP synthase which rotates due to energy provides by the protons during proton flux.
When proton moves through F₀ unit down their concentration gradient, it provides energy to the F₁ subunits which bind ADP and inorganic phosphate to release ATP.
Thus, Option-C is the correct answer.
<span>Both of these show the distribution of phenotypes. In directional selection, the distribution of phenotypes forms a "bell curve." Selection against one of the extreme phenotypes causes the distribution to "move" in one direction or the other. An example might be plants whose flower color is determined by incomplete dominance: white, pink, or red. Pink flowers may be the average phenotype, but if we start to remove red flowers from the population, the "mean" phenotype will be shifted toward white flowers.
In disruptive selection, the average phenotype is selected against. This produces a "two-humped" bell-type curve, and the greater distribution is split between the two phenotype extremes. If we have the same type of incomplete dominance as mentioned in the previous paragraph, assume that the pink flowers are selected against. This means that the two "humps" shown in the distribution will be centered around the red and white phenotypes.</span>
