Answer:

To decrease workload of the heart .

Explanation:

These blockers are used in the treatment of CAD to decrease the myocardial oxygen by reducing heart rate and workload of the heart.

Nitrates are used for vasodilation.

Anti-lipid drugs are used to decrease homocysteine levels.

ACE inhibitors inhibit the conversion of angiotensin.

allsm [11]

Answer:

Protein B has a higher affinity for ligand C than protein A

Explanation:

Binding affinity is a measure of the strength of the bonds or interactions between a single biomolecule or receptor to its ligand. A ligand is usually a small molecule that binds to a specific receptor.

The receptor is usually a large molecule that contains a specific site for the binding of ligand.

Binding affinity is usually measured by the equilibrium dissociation constant (KD). The equilibrium dissociation constant KD is a ratio of the dissociation and the association of ligand to the receptor. The value of KD is used to evaluate and compare the strengths of bimolecular interactions.  The larger the KD value, the more weakly the target molecule and ligand are attracted to and bind to one another.

The higher the dissociation constant (KD), the weaker the affinity is between the interacting molecules, whereas, the smaller the KD value, the greater the binding affinity of the ligand for its target.

Protein B has a KD value of 10⁻⁹ M while Protein A has a KD of 10⁻⁶ M.

Ration of KD of protein B to protein A = 10⁻⁹ M/10⁻⁶ M = 10⁻³

Therefore, protein B has a KD value which is 1000 times smaller than the KD of protein A.

Which organelle contains DNA and controls the activity in the cell?<br> ОВ<br> Ос<br> OD<br> ОЕ
IrinaK [193]

Nucleus can be defined as a large organelle found in the Eukaryotic cells and it is also  know as the cell's command center,thus it controls the activity of the cells

Explanation:

  • The answer to the above question is (c )nucleus. During the cell cycle the nucleus of the cell mediates the replication of the of the DNA and controls the gene expression.
  • The nucleus contains a structure which is known as nucleolus and which is made up of protein and ribonucleic acid(RNA)
