Question

True of False:

Vitamins and minerals are very important to health, they are absorbed without any change during digestion. (     )

The human body needs fatty acids, and it can make all but two of them—linoleic acid (the 18-carbon omega-8 fatty acid) and linolenic acid (the 18-carbon omega-3 fatty acid). (     )

Sometimes a nonessential amino acid might become essential under special circumstances. (    )

the cells of the pancreas do not make the protein hemoglobin, which is needed only by the red blood cells.                                      (     )

When nutrients enter the body from the digestive tract, the stomach receives them first; then it metabolizes, packages, stores, or ships them out for use by other tissues. ( )

Acetyl CoA can readily make fat. And glucose.                   (     )

Choose the best answer to the following questions:

Which of the following sugar is NOT a monosaccharide:          (     )    

1. Glucose (B) Fructose (C) Galactose (D)Maltose

Which of the following statement about fatty acid is WRONG:     (      )

(A) All of the energy-yielding nutrients—protein, carbohydrates, and fat—can be broken down to acetyl CoA.

(B) Acetyl CoA can enter the TCA cycle or it can make fat.

(C) In the end of Energy Metabolism, oxygen is consumed, water and carbon dioxide are produced, and energy is captured in ATP

(D) Fatty acids can be used to make glucose.

In estimating energy requirements, the DRI Committee developed equations based on research measuring total daily energy expenditure. These equations consider how the following factors influence BMR and consequently energy expenditure, which of the following is not included:                         (      )

(A)Gender. (B) Race (C)Age. (D) Physical activity.

For building fitness and minimizing the risk of overuse injuries, which of the following tip should be considered:

1. Be active all week, exceptt on the weekends.

(B) Use proper equipment and wear proper attire while doing dangerous exercises.

(C) Perform exercises using proper form.

(D) Include warm-up and cool-down activities in the beginning and at the end of exercise.

1. The higher the blood pressure is above normal, the greater the risk. Low blood pressure is generally a sign of long life expectancy and low heart disease risk.. What is your recommendation on “how to implement a Heart-Healthy Diet”.

2. What is the harmful effects of excessive fiber intake?

3 To be more healthy, what would you Plan a Healthy Diet with a daily variety of foods .

4 Some fats in the diet are essential for good health, but others can be harmful. For this reason, recommendations focus both on the quantity and the quality of the fat in the diet. Both the amounts and types of fat in the diet influence the risk for disease. Please give 3 or more examples to illustrate the point.

Answer 1

1) Vitamins and minerals are very important to health, they are absorbed without any change during digestion. ( False)

True Explaination :-

Vitamins and minerals are very important to health, they are absorbed after changing during digestion.

2) The human body needs fatty acids and it can make all but two of them - linolein acid ( the 18- carbon omega- 8 fatty acid) and linoleic acid ( the 18- carbon omega- 3 fatty acid) . ( True)

Explaination :-

The human body is capable of synthesizing most of the fatty acids it needs from the food except linoleic acid and linolenic acid as they cannot be synthesized by human.

3) Sometimes a non- essential amino acid might become essential under special circumstances.( True)

Explaination:-

Some amino acids are essential because they cannot be made by our bodies or are made too slowly for our needs. Sometimes non- essential amino acids can become essential under special circumstances. If amino acids are lacking , the body cannot make the protein it needs to perform different functions.

4) The cells of the pancreas do not make the protein hemoglobin which is needed only by the red blood cells. ( True)

Explaination :-

Nearly all of the body's cells posses the genes for making all human proteins but each type of cell makes only the protein it needs. Example :- Cells of the pancreas express the gene for insulin, in other cells that gene is idle. Similarly , the cells of the pancreas do not make the protein hemoglobin which is needed only by the red blood cells.
