Respiration

Respiration refers to the process by which living organisms use oxygen to produce energy. Inside the cells of an organism, energy is released when organic substances such as glucose react with oxygen and are converted into carbon dioxide and water. This energy is essential for the growth and activity of organisms, and the reaction is vital for sustaining life. Respiration also affects sake production, particularly in fermentation processes involving plants and yeast. In sake brewing, yeast converts sugar into alcohol through respiration, so the respiration process is closely tied to the quality and flavor of the sake.
