Which transfer molecule allows the energy in food to be delivered cells for their use?

The transfer molecule that allows the energy in food to be delivered to cells for their use is ATP,

ATP stands for adenosine triphosphate. It is a molecule that cells use to store and release energy. ATP is produced in the mitochondria of cells, which are small organelles that act as the power plants of cells. ATP consists of three phosphate groups attached to a molecule of adenosine, a nitrogenous base.

When a cell needs energy to perform a task, it breaks down ATP into ADP (adenosine diphosphate) + Pi (inorganic phosphate). This reaction releases energy that the cell can use to power various processes, including muscle contraction, nerve transmission, and chemical synthesis.

The energy stored in ATP is derived from the breakdown of organic molecules, such as carbohydrates (glucose) and fats (lipids), through the process of cellular respiration. During cellular respiration, these organic molecules react with oxygen to produce ATP and carbon dioxide as waste products.
