Adenosine triphosphate(ATP)
sunlight
A solar cell is not an energy source, but an energy converter. In the case of solar, the energy source is light, and the solar cell converts it from light energy to electrical energy.
The sun is the major external source of energy.
The mitochondria is known as the powerhouse of the cell because it is responsible for converting nutrients into adenosine triphosphate (ATP), the cell's primary energy source. This process is known as cellular respiration.
Carbohydrates
the major source is sun
A cell's main souce of energy is glucose.
solar light is the source of energy for a solar light
Glucose is a sugar, so yes it is a source of energy.
glucose
The powerhouse of the cell is the mitochondria. It generates energy for the cell through a process called cellular respiration, producing ATP molecules that serve as a major energy source for various cellular activities.
ATP is called the energy source (battery) of the cell.
