Final answer:
In cooking, energy is derived from nutrients absorbed by the digestive system and transported by the circulatory system to cells, where mitochondria generate ATP for the muscles to perform cooking actions.
Step-by-step explanation:
When you are cooking, energy transfers from your body to the cooking utensils and the food. The digestive system breaks down food into smaller molecules, which are then absorbed into the blood. The circulatory system transports these nutrients to various cells in the body, including muscle cells. Within these muscle cells, organelles known as mitochondria carry out the process of cellular respiration, which converts these nutrients into adenosine triphosphate (ATP), the energy currency of the cell.
This ATP is then used by the muscles to exert force on cooking utensils, which in turn interact with the muscular system. The muscular system consists of many types of cells, including skeletal muscle cells, which contract and apply force aided by the skeletal system. The interaction between your muscles and bones allows you to perform the actions required for cooking, such as stirring or flipping, that apply forces to your cooking utensils and move your object, in this case, the food.
