Answer:
C- Impair the ability to consider the consequences of acting impulsively
Explanation:
Alcohol consumption leads to an increase in the level of dopamine released in the brain, thus increasing pleasure. This increase in levels of dopamine can lead to impairment in reasoning and minor memory loss. With these factors, impulsive actions are more likely to occur. Aggressive behavior might eventually settle in, when euphoria eventually becomes depression.
Answer:
p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.
Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.
<u>Answer:</u>
ATP or the Adenosine Triphosphate is the energy currency of the living world, which transfers energy from one organic molecule to other, even from one cell organelle to other.
<u>Explanation:</u>
The functional group of ATP is phosphate which is quite evident from its name.
Adenosine diphosphate is the parent molecule. During either photophosphorylation or the respiration, the Inorganic phosphate molecule that is present in the cellular fluid gets attached to the parent molecule ADP via a high energy bond which is broken to give energy to the normal reactions.
