Cellular respiration is a fundamental process in plants where glucose and oxygen are converted into water, carbon dioxide, and ATP, releasing energy that drives various cellular functions. In the context of plant physiology, it is a critical aspect of energy metabolism, enabling plants to grow, develop, and respond to their environment. Within the broader categories of science and chemistry, cellular respiration provides an excellent example of how biological systems utilize chemical reactions to generate energy and maintain homeostasis. It involves several stages, including glycolysis, the Krebs cycle, and the electron transport chain, each with its unique set of enzymes and intermediate compounds. By studying cellular respiration in plants, researchers can gain insights into the molecular mechanisms that underlie energy metabolism and how they contribute to plant health and productivity.
