Answer: The correct answer is the last option.

Explanation:

Carrier identification test is a screening test that tells if a person is carrier of a particular autosomal recessive disease. It helps in determining the possibility of passing that disease to a child.

Genetic counsellor is professional who is expert in human genetics, research, lab work, counselling, et cetera. After the test, it is best to contact a genetic counsellor as he can explain the family pedigree of the disease. He can best explain the probability of passing a genetic disease to the child.

An enzyme contains a catalytic histidine residue in its active site that must release an R group proton to solution in order to

Options missing:

a) The pH of the environment should be relatively high.

b) The pH of the environment should be relatively low.

c) The pH of the environment would not matter.

d) The environment should be set to the biochemical standard state.

Answer:

a) The pH of the environment should be relatively high.

Explanation:

For optimal function an enzyme needs a certain environment or condition. As temperature increases, the rate of enzyme activity also increases. As temperature increases toward its optimum point of 37 degrees Celsius (98.6 F), hydrogen bonds relax and make it easier for the hydrogen peroxide molecules to bind to the catalase.

The part of the enzyme where this reaction takes place is called the active site. A temperature that is higher or lower than this optimum point changes the shape of the active site and stops the enzyme from working. This process is called denaturation.

Enzyme pH levels also change the shape of the active site and affect the rate of enzyme activity. Each enzyme has its own optimal range of pH in which it works most effectively. In humans, catalase works only between pH 7 and pH 11. If the pH level is lower than 7 or higher than 11, the enzyme becomes denaturated and loses its structure. The liver sustains a neutral pH of about 7, which creates the best environment for catalase and other enzymes.

General acid catalysis would require histidine to be protonated at pH values (pH 8.0) optimal for enzymatic activity which is relatively high.

What happened to the eggplant after adding salt?
ivanzaharov [21]

Answer:

Salting eggplant is often explained on two points: The first point contends that eggplants can be quite bitter, and salting helps cut the bitterness. (No, salt doesn't draw out bitterness. It just helps hide it.) Second, salting eggplants reduces the sponginess and leaves you with a creamy, silky texture.
