👉 Diathermaneity is a term used in the field of biochemistry and physiology to describe the phenomenon where an enzyme, such as an adenosine triphosphate (ATP) synthase, becomes inhibited or inactivated by a second molecule of ATP. This inhibition can be caused by a variety of factors, including changes in pH, temperature, or other environmental conditions that alter the activity of the enzyme. In biochemistry, this phenomenon is often referred to as "deactivation" or
