Katabolismissa

Katabolismissa is a Finnish term that translates to "in catabolism" or "during catabolism." It refers to a phase or process within the broader metabolic system of an organism. Catabolism itself is the set of metabolic pathways that break down molecules into smaller units that can be oxidized to release energy in the form of ATP. Therefore, when something is described as occurring "katabolismissa," it signifies that it is happening during this breakdown phase of metabolism.

This process involves the degradation of complex organic molecules, such as carbohydrates, fats, and proteins, into simpler substances like carbon dioxide, water, and ammonia. During katabolismissa, energy is released and captured for cellular activities. For instance, the breakdown of glucose through glycolysis and the subsequent stages of cellular respiration are processes that occur katabolismissa. Similarly, the breakdown of fatty acids in beta-oxidation and the deamination of amino acids also fall under this category. The term implies an active metabolic state where stored energy reserves are being mobilized and utilized.
