Katabolizma is a metabolic process in which complex molecules are broken down into simpler ones, releasing energy in the process. This energy is essential for various bodily functions, including movement, growth, and maintaining body temperature. Katabolizma plays a crucial role in how the body utilizes nutrients from food. During katabolizma, substances like carbohydrates, fats, and proteins are decomposed. For example, when the body breaks down glucose, it releases energy that can be used immediately or stored for later use. This process is vital for maintaining overall health and supporting daily activities.
