Chapter 10, Problem 1RQ

Summary Introduction

Concept Introduction:

Monosaccharide is the simplest form of carbohydrate. They cannot be broken down since they consists only a single sugar group. Examples of monosaccharide include fructose (sugar) and glucose (blood sugar). Cells can utilize the glucose found in food directly for energy; meanwhile fructose is converted to glucose in the liver.

Answer to Problem 1RQ

Correct answer:

The correct option is (a) ‘that may help maintain hydration and contribute to blood glucose’.

Explanation of Solution

Option (a) is given ‘that may help maintain hydration and contribute to blood glucose’. During short, intense physical exercise (like wrestling or boxing), monosaccharide is the only fuel having ability of providing the body with energy quickly enough. In the first few minutes of any intense physical activity, it is carbohydrate that almost exclusively meets energy demands. This is the basic unit of carbohydrate. So, it is the correct answer.

Option (b) is ‘also called electrolytes, to help replace those lost during physical activities’. Monosaccharide is broken into fructose and glucose and not electrolyte which help to replace the energy lost during physical activity. Hence, option (b) is incorrect.

Option (c) is ‘that provide a nutrient advantage to most people’. Monosaccharides are non-essential nutrients. It means the body can produce all of those it needs for proper functioning from other nutrients, so monosaccharide do not need to get them from food. Also, they are not advantageous for every individual. Hence, the option (c) is incorrect

Option (d) id given as ‘a and c’. Option (a) is correct but option (c) does not justify an answer with (a). Hence, option (d) is given (a) and (c) is incorrect answer.

Hence, options (b), (c), and (d) are incorrect.

Conclusion

Therefore, monosaccharide in sports drinks helps to maintain hydration and contribute to blood glucose.
