What is the process in which the body produces and uses energy from food?

The process in which the body produces and uses energy from food is called metabolism. It involves two main components: catabolism, where food is broken down into smaller molecules to release energy, and anabolism, where these molecules are used to build and repair tissues. Carbohydrates, fats, and proteins are converted into glucose and other energy-rich compounds, which are then utilized by cells to fuel various biological functions. Hormones and enzymes regulate these metabolic pathways to maintain energy balance and support overall health.
