Answer:
The protein phosphatase-1 dephosphorylates the residues of serine, which are phosphorylated by the protein kinase A. The cyclic-AMP inducible genes are stimulated by CREB that is phosphorylated by protein kinase A. Thus, overexpression of protein phosphatase 1 would prevent their induction.
Although, protein phosphatase 1 would not influence the function of cAMP-gated ligand channels, as these channels are opened directly by binding of cAMP rather than by protein phosphorylation.
The antimicrobial activities in the mouth are hydrochloric acid denatures proteins and killing many microbes.
The capability of an hydrochloric acid activating pathogen-killing compounds is not a part of insect immunity,There has recently been an increase in interest in trehalose metabolism for therapeutic applications due to trehalose's relevance in numerous pathogenic species.The most significant biosynthetic process is the enzyme TPP (trehalose-6-phosphate phosphatase) (OtsAB).
Here, five important nematode and bacterial pathogens' recombinant TPPs, including three new members of this protein family, are compared for their enzyme characteristics.
The kinetics of the hydrolysis of trehalose-6-phosphate show that all five enzymes display burst-like kinetic behaviour, which is characterised by a decrease in enzymatic rate beyond the pre-steady state.
The observed super-stoichiometric burst amplitudes can be explained by many global conformational changes that occur in members of this enzyme family during substrate processing.

The value of n, the Hill coefficient, for hemoglobin is about 2 to 3 times as great as the value for myoglobin.
Hill Equation
The two closely related equations that help to explain the binding of macromolecules to ligands are called the Hill equation. It helps to quantify the interaction between various ligand binding sites.
Hill coefficient
It is used to describe the cooperativity of ligand binding. It can be positive and negative depending on the value of the Hill coefficient. If the value of the Hill coefficient is more than one then it exhibits positively cooperative binding and if it is less than one then it exhibits negatively cooperative binding. Then there is the noncooperative binding where the Hill coefficient value is one. As for the hemoglobin and myoglobin, the values are,
- Hill coefficient of hemoglobin is 2.7 - 3.
- Hill coefficient of myoglobin is 1.0.
Thus hemoglobin is positively cooperative and myoglobin exhibits noncooperative binding.

Answer:
Diffusion is the process of small molecules moving from a high concentrated area to a lower concentrated area. For example, in a crowded train station, when a train arrives, people move from the high concentrated area, which is the platform, and move onto the lower concentrated area, which is the trian.
Explanation:
The process of diffusion does not cost any energy, as it happens naturally, and would cost energy to go against it, like trying to go from the train into the platform costs more energy than just going with the crowd into the train. And only small molecules can do this without using energy. Large molecules, like starch, can't do this without using energy.(ATP) hopefully, this helped you, and it would mean a lot to me if you could give me brainliest!
The nucleus is the part which controls the cell and is semipermeable
