Answer:
B. binds to the tryptophan repressor when the repressor is bound to tryptophan.
Explanation:
Bacterial genes are commonly composed of operons that are activated or deactivated depends on the needed. If the bacteria need, for example, an amino acid such as tryptophan for synthesizing proteins. An activator "turns on" the transcription that the operon has and produces the amino acid.
On the other hand, if the bacteria have a high presence of tryptophan amino acid, a repressor binds to the tryptophan operator and avoids the amino acid transcription, in consequence, constrain the tryptophan production.
+⇔
Decreasing the temperature of the reaction,the reaction shifts forward.
The explanation is given below.
Explanation:
If the temperature of the reaction mixture is increased,then the equilibrium will shift to decrease the temperature.
If the temperature of the reaction mixture is decreased,then the equilibrium will shift to increase the temperature.
During the formation of the ammonia,it gives off heat.So it is an exothermic reaction.
+⇔
A decrease in the temperature favors the reaction that is exothermic (the forward reaction)because it produces energy.Therefore,if the temperature is decreased,the yield of the ammonia increases.
<em>Therefore if the temperature is increased,the reaction shifts forward and the yield of the ammonia increases and it is an exothermic reaction.</em>
Answer:
it is false
Explanation:
it goes in different ways not in order
Answer:
Option (D)
Explanation:
Phosphorylation can be simply defined as the addition of a phosphate group to an organic and inorganic molecule. This process helps in regulating the processes that occur in the cells. It leads to the growth and development of cells and this process is efficiently carried out with the help of enzymes like kinase. It also plays an important role in transferring the signals within the cells, synthesis, and functioning of proteins within the cells, and storing as well as releasing of energy.
Thus, the correct answer is option (D).
