ATP stands for adenosine triphosphate. This means that there are 3 phosphate groups in the molecule, which are linked to the adenosine with very high energy covalent bonds. Whenever any of these phosphate groups' bonds is broken, it releases all of the energy that was involved in the bond. It is converted to ADP (adenosine diphosphate) and so on by enzymes, that can break the covalent bonds to phosphate groups and release the big pack of potential energy.
Glucose is the primary energy source for the brain. It is converted into ATP, which is the main source of energy for brain cells to function and communicate effectively. Adequate glucose supply is crucial for optimal brain function.
The above example is considered a load because it consumes energy from the source it is connected to. It draws power from the source to operate or perform its function. In contrast, an energy source is a provider of energy that can supply power to a load.
Glucose is the preferred source of energy for the human body because it is easily broken down and converted into energy, providing a quick and efficient fuel source for cells to function properly.
The energy source a person is using when lifting a chair is chemical energy stored in their muscles. When a person contracts their muscles to lift an object, chemical energy from food they have eaten is converted into mechanical energy to perform the task.
In an energy source, such as a power plant or a battery, energy is converted from one form to another. For example, in a power plant, mechanical energy from a turbine is converted into electrical energy. In a battery, chemical energy is converted into electrical energy.
Glucose is the preferred energy source for the human body because it is easily broken down and converted into energy, providing a quick and efficient source of fuel for cells to function properly. Additionally, glucose can be stored in the body for later use, making it a reliable and readily available source of energy.
The body needs carbohydrates as a source of energy. Carbohydrates are converted into glucose, which is a form of sugar, the body uses to support the function of the muscles and brain.
Energy is added in the illustration through the input of some external source, such as a battery or a power supply. This external source provides the necessary energy to the system, allowing it to perform its intended function.
A hand mixer typically operates using electrical energy. When the mixer is plugged into a power source, the electrical energy is converted into mechanical energy to rotate the beaters and mix ingredients. This mechanical energy is what allows the hand mixer to perform its mixing function efficiently.
Producers, such as plants, derive energy from sunlight through the process of photosynthesis. This energy is converted into chemical energy stored in molecules such as glucose.
The body needs carbohydrates as a source of energy. Carbohydrates are converted into glucose, which is a form of sugar, the body uses to support the function of the muscles and brain.
Oil has a reserve of chemical energy. If we burn it, that gets converted to heat energy.
