The pKa of an acid depends partly on its environment. Predict the effect of each of the following environmental changes on the p
Galina-37 [17]
The pKa represents the pH of the medium at which the zwitterionic amino acid assumes most stable ionic form due to structural stabilization. As the pKa is dependent upon the environmental factors of the solution around the amino acids, a change in their structure and localization can cause change in the pKa of the protein. Thus, the answers can be found as below:

Part A: Decrease (As the lysine is basic in nature, it will tend to stabilize the electrostatic interaction and weak interactions between the acidic amino acids and hydrogen bonds in the viscinity, thus lowering the pH and hence pKa of the protein)

Part B: Increase (As the carboxyl group is acidic in nature, removal of it will tend to increase the pKa since the basic amino acids will tend to accumulate more negative charge in their viscinity)

Part C: Increase (As glutamic acid is an acidic amino acid, its shift from outside to a non-polar site will prevents its ionization and hence the pKa will tend to shift from slightly acidic to slightly basic, hence increase)

What geological feature is located below an active volcano
frez [133]

Answer:

Below an active volcano lies magma chamber. Magma is the liquid which makes the lava. It’s located within the crust of the earth.

Explanation:

Magma chambers lies within the crust of the earth. Volcano is made up of magma which has come in contact with water. Upon contact with water, it erupts.

Once the volcano erupts it can destroy all forms of life surrounding it. The parts where the lava has fallen are no more capable of inhibiting.
