Answer to Problem 1E

Correct answer:

Among the answers given, the correct answer is option c) eicosanoids.

Explanation of Solution

Explanation for the correct answer:

The option (c) is eicosanoids. the arachidonic acid is converted into the eicosanoids by the action of certain enzymes. Cyclooxygenase (COX) is required in the conversion of arachidonic acid into the prostaglandins. On the other hand, lipoxygenase is required in the conversion of arachidonic acid into the leukotrienes. The function of eicosanoids is to give an immune response to the body.

Explanation for the incorrect answer:

The option (a) is amines. The amines are the derivatives of the ammonia. We can replace hydrogen atoms of the ammonia with the carbon groups, so that, we can get an amine. Hence, this option is incorrect.

The option (b) is thyroid hormones. Thyroid hormones are the thyroxine-based hormones and have precursor thyroglobulin. Hence, this option is incorrect.

The option (d) is steroids. Steroids are the hormones that help in the metabolism, maintain salt-water balance, immune functions, and development of sex characteristics. Its precursor is cholesterol. Hence, this option is incorrect.

The option (e) is peptides. Peptides are the group of amino acids that are linked by the peptide bonds. So, peptides are made up of the amino acid units. Hence, this option is incorrect.

Conclusion

Hence, the arachidonic acid is the raw material for the eicosanoids. So, the correct option is c).

Older adults have unique challenges in terms of their nutrient needs and physiological changes. Some changes may make it difficult to consume a healthful diet, so it is important to identify strategies to help overcome these obstacles. From the list below, choose all the correct statements about changes in older adults. Select all that apply.   Poor vision can make it difficult for older adults to get to a supermarket, and to prepare meals. With age, taste and visual perception decline. As people age, salivary production increases. In older adults with dysphagia, foods like creamy soups, applesauce, and yogurt are usually well tolerated. Lean body mass increases in older adults.
When physical activity increases, energy requirements increase also. Depending on the type, intensity, and duration of physical activity, the body’s requirements for certain macronutrients may change as well. From the list below, choose all the correct statements about the effects of increased physical activity or athletic training. Select all that apply. An athlete who weighs 70 kg (154 lb) should consume 420 to 700 g of carbohydrate per day. How much additional energy an athlete needs depends on the specific activity the athlete engages in and the frequency of the activity. Those participating in vigorous exercise should restrict their fat intake to less than 15%% of total energy intake. Athletes who are following energy-restricted diets are at risk for consuming insufficient protein. The recommendation to limit saturated fat intake to less than 10%% of total energy intake does not apply to athletes or those who regularly engage in vigorous physical activity.
When taking vitamins and vitamin-mineral supplements, how can one be sure they are getting what they are taking?
