The islets of Langerhans are microorgans located in the pancreas.

<h3>The islets of Langerhans </h3>

The islets are formed by polygonal or rounded cells, arranged in cords, around which there is an abundant network of blood capillaries with fenestrated endothelial cells.

<h3>Types of islets of Langerhans</h3>
  1. Alpha (A) cells: secrete glucagon. In humans, these cells have regular-shaped granules containing a dense center surrounded by a clear region under the membrane.
  2. Beta (B) cells: secrete insulin and amylin. B cells have irregular granules with a center formed of irregular crystals of insulin complexed with zinc.
  3. Delta cells (D): synthesize somatostatin.
  4. PP (F) cells: contain a pancreatic polypeptide.

With this information, we can conclude that the islets of Langerhans are microorgans that constitute a large production of products for the maintenance of life.

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.
