PLEASE SOLVE CORRECTLY GUYS ​

Answer 1

1.Good nutrition aims to achieve and maintain a desirable body composition and high potential for physical and mental work. Balancing energy intake with energy expenditure is necessary for a desirable body weight.

2.glucose

3.There are seven essential factors for a balanced diet: carbs, protein, fat, fibre, vitamins, minerals and water.

4.Carbohydrates are truly hydrates of carbon because the ratio of hydrogen atoms to oxygen atoms is always nearly 2:1, as in H2O. They also have many functions. Most of the energy you receive comes from the carbohydrates that you eat.

5.(CH2O)x, where conventionally x ≥ 3. Monosaccharides can be classified by the number x of carbon atoms they contain: triose (3), tetrose (4), pentose (5), hexose (6), heptose (7), and so on.

6.Disaccharides are one of the four chemical groupings of carbohydrates (monosaccharides, disaccharides, oligosaccharides, and polysaccharides). The most common types of disaccharides—sucrose, lactose, and maltose—have 12 carbon atoms, with the general formula C12H22O11.

7.(C6H10O5)n

9.Cellulose is the main substance found in plant cell walls and helps the plant to remain stiff and strong.

10.Functions of roughage: Its main function is to add bulk to the diet, which in turn aids in the digestion process and healthy Function of the bowel system. Prevents constipation and helps in getting rid of undigested food. They help in retaining water in the body.

11.Fiber, also known as roughage, is the part of plant-based foods (grains, fruits, vegetables, nuts, and beans) that the body can't break down.

12.The metabolism of glucose is representative of that of carbohydrates. If we begin with 1 mole of glucose (180 g) and oxidize it with 6 moles of oxygen molecules, there are 6 moles of carbon dioxide, 6 moles of water and 686 kcal of energy produced.

HAVE A NICE DAY....

Answer 2

Answer:

1.we need nutrition for

• proper growth
• good development

2. carbohydrate

3.carbs, protein, fat, fibre, vitamins, minerals and water

4. 2:1

5. CnH2nOn

6. C12H22O11

7. Cx(H2O)y

8. fructose

9. plant cell wall

10. Roughage is simply referred to as dietary fiber. It is the indigestible portion of food obtained from plants. They do not provide any nutrient to our body but play an essential part of a healthy diet plan. Functions of roughage: Its main function is to add bulk to the diet, which in turn aids in the digestion process and healthy Function of the bowel system. Prevents constipation and helps in getting rid of undigested food. They help in retaining water in the body. Some roughage foods include fruits, apples, pears, and whole grapes, whole grains and green leafy vegetables.

11. wholemeal flour, fruit, vegetables, nuts, seeds and pulses such as peas, beans and lentils are major sources of fiber

12. 686 kcal. energy is produced by 1mole of glucose
