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: （）

(A) 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.

Answer 1

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

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)are taken from outside. (True )

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

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

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.(False)-all these steps occurs in the duodenum.

Acetyl CoA can readily make fat. And glucose.(False)-acetyl co A can not be converted back to pyruvate so it can not be converted back to glucose.

• (D)Maltose is a disaccharide formed by the combination of 2 units of glucose monosaccharide.
• (D)fat can not be converted back to glucose. Because pyruvate dehydrogenase is a irreversible step which can not convert Acetyl co A back to glucose.
• (B)Race has no effect on BMR of the body. But gender,age and physical activity has effect on BMR.in females BMR is found to be lower than men because they have less muscle mass and more body fat. As the age increase muscle mass decrease body become lean. Physical activity effects BMR ,it keeps BMR in normal range if the person do physical activity.
• All the options are correct there should always be a proper dorm of doing exercise With proper equipments and rest should always be given to the body to recover from the overuse.
