The number one source of energy for the human body is carbohydrates, which are broken down into glucose to provide fuel for our cells. Other sources of energy include fats and proteins.
groundnut is a source of nitrogen.
solar (sun) hydro(water)
The Sun is one source of energy.
One molecule that fits this description is glucose. Glucose is a source of energy as it can be broken down during cellular respiration to release energy, it can be stored in the body as glycogen for later use, and it can mix with water to form a solution due to its hydrophilic nature.
It is a source of calories, which is a form of energy. Without sufficient exercise, this type of energy produces additional fat in the body. The other type of energy is when we feel 'energetic' as a result of fitness and vitality. Eating pizza is not necessarily a good source for this type of energy. So one word 'energy' has two different meaning. The food industry uses this confusion to sell products that don't necessarily make you energetic.
Exothermic. Glucose is one of the major source of energy of the body and can only act as an energy source because its breakdown into CO2 is an exothermic reaction.
The body cannot use water as a source of energy, although it is essential to life. Water contains no calories because the human body cannot metabolize it further to get energy (calories) out of it. This is unlike, say sugar or carbohydrates, that the body digest, metabolizes and gets energy out of. Water is essential for other processes in the body, but it is not converted in any way to make energy.Calorie- The amount of heat energy needed to raise the temperature of one gram of water one degree C.Carbohydrate - An essential nutrient that is the body's main source of energy.
A. A sustainable energy source is one that will not run out. This is because sustainable energy sources like solar, wind, and hydropower are renewable and can be used indefinitely without depleting their source.
One of the three main classes of foods is carbohydrates, which are a primary source of energy for the body. Carbohydrates are found in foods like grains, fruits, and vegetables, and they are broken down into glucose, which fuels bodily functions and physical activity. They are essential for maintaining energy levels and supporting brain function.
Vitamins are not a source of energy for the body. While they are essential for various metabolic processes and overall health, they do not provide calories like carbohydrates, proteins, and fats do. Instead, vitamins serve as co-factors in enzymatic reactions and help in the utilization of energy from other nutrients.
