Pepsi [2]

Answer:

The correct option is: <em>a deficiency of dopamine in the substantia nigra.</em>

Explanation:

The substantia nigra is the principal site involved in the physiopathology of Parkinson´s disease.

Cells from this area degenerate and die progressively causing important degeneration in the central nervous system. The cells that die -with no known reason- are those that produce dopamine and proportionate dopaminergic innervation to the encephalon. In fact, almost all the symptoms exhibited by patients with the disease can be explained by the lack of dopamine in the substantia nigra.  

This area uses the neurotransmitter to communicate neurons from the base ganglia. Ganglia are responsible of modulating and modifying movements.

The nigrostriatal system participates in planning and automatic execution of learned movements. When the ganglia activity decreases, so it does the amount and velocity of movements, something typical of the disease.

Does Ajay’s diet provide enough protein to meet his RDA of 0.8g/kg of body weight? (2.2lbs = 1kg)

Answer:

The correct answer is yes.

Explanation:

RDA or recommended dietary allowance refers to the minimum amount of a nutrient, that is, regarded as essential for the proper functioning of the body or to sustain good health. The RDA is formulated by the Nutrition Board of the National Research Council.  

In the given case, the weight of Ajay is 154 pounds. In terms of kilograms, 1 kg is equivalent to 2.2 pounds.  

Thus, 154 pounds will be equal to 154/2.2 = 70 Kg.  

Based on RDA, the requirement of protein for a healthy individual should be 0.8 g/kg of the body weight. Therefore, Ajay needs to consume 70*0.8 = 56 grams of protein. However, based on his diet he is consuming 78 grams of proteins in a day. Hence, it can be concluded that Ajay is consuming adequate protein to meet his RDA.
