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.
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.
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.
The three sources of food energy are protein, carbohydrates (sugars), and fats.
One example of an energy change that occurs in your body is the conversion of glucose into ATP (adenosine triphosphate) during cellular respiration. Glucose is broken down in the presence of oxygen to produce ATP, which is used as the primary energy source for cellular processes.
