PCH ANSWER: Nutrient first of all you must know that there are three form of nutrients or substances that are really important to keep the body in tip top shape. these are the carbohydrates, proteins and fats. carbohydrates are used mainly to provide energy to all cells in the body. proteins' main functions are for cell growth and repair although they can also provide energy. the fats on the other hand is rarely used for energy though it provides the highest amount because if the body does so, it can lead to ketoacidosis. they function mainly in insulation.
protein
Teenagers have high energy needs due to their rapid growth and development, increased physical activity levels, and metabolic rate. Their bodies require more calories and nutrients to support these processes and meet the demands of a growing body.
Heat is a form of energy that results from the movement of particles within a substance. This movement generates thermal energy, which can be transferred from one object to another through conduction, convection, or radiation. Heat is commonly measured in units of joules or calories.
Both males and females require energy to support basic metabolic functions, physical activity, growth, and reproduction. However, males generally have higher energy needs due to their higher muscle mass and metabolic rate. Differences in hormones and body composition can also influence energy requirements between the sexes.
Temperature refers to the degree of hotness or coldness of a body. It is a measure of the internal energy of a substance.
The decrease in body energy requirements with age is primarily due to a decrease in muscle mass and a decline in metabolism. As we age, we tend to become less physically active, which reduces the amount of energy our body needs. Additionally, hormonal changes and a decrease in organ function further contribute to lower energy needs as we get older.
Nutrients are the substance in foods that the body needs to promote growth and repair body, tissues, and to get energy. The body needs nutrients including protein to regulate bodily functions.
body needs food for growth, energy and repair
A nutrient is needed by the body to promote normal growth, provide energy, repair and more. :)
carbohydrates
Lean body mass. Growth period. Body tempreture . hormonal stasus
The substance found in foods that is energy-rich is called macronutrients, specifically fats, carbohydrates, and proteins. These macronutrients provide the body with the energy it needs to function properly.
In food, there are many macro molecules. Among them, the main contribution towards the energy is given by the carbohydrates and fats. For the development, growth and repair our cell needs proteins and other micro nutrients like vitamins and minerals.
Teenagers have high energy needs due to their rapid growth and development, increased physical activity levels, and metabolic rate. Their bodies require more calories and nutrients to support these processes and meet the demands of a growing body.
Basal Energy expenditure is the amount of energy needed by the body for maintenance of life when a person is at complete digestive, physical, mental, thermal, and emotional rest. The factors that influence non basal energy needs are lean body mass, growth periods, body temperature, and hormonal status.
The energy a body needs comes from the food consumed or eaten.
