The answer would be: taking-in phase
Rubin postpartum emotional phase is divided into 3. The first phase is called taking in. In this phase, the mother is more focused on her need(resting after delivering the baby, food, or water). The phase is usually last for 2-3 days.
After this phase, there will be taking-hold phase and letting-go phase.
Answer:
C. The enzyme with mutation 1 has decreased affinity for pyridoxal phosphate, whereas the enzyme with mutation 2 has lost the ability to bind to the substrates.
Explanation:
A coenzyme is an organic cofactor that binds with an enzyme in order to initiate or aid the function of the enzyme. A coenzyme binds to the active site of the enzyme (where the reaction occurs), thereby triggering its activation by modifying protein structure during the reaction. Some examples of coenzymes include Coenzyme A and Adenosine triphosphate (ATP). Pyridoxal phosphate is a coenzyme (it is the active form of vitamin B6) that is required for the function of cystathionase. Moreover, cystathionase is an enzyme that enables cells the synthesis of cysteine from methionine (transsulfuration pathway). The binding of pyridoxal phosphate to the enzyme increases the binding affinity of the enzyme for the substrate, thereby influencing its activity. In this case, it is expected that mutation 1 reduces the binding affinity of the enzyme to the cofactor, and thereby the cofactor is required at a higher concentration to restore normal enzyme activity.

The answer is A.
You can remember this by thinking that since there was no change in the amino acid sequence, the mutation is silent in the fact that it didn't cause any trouble in the amino acid sequence.
