Key Concepts

Ectothermy

Ectothermy refers to the phenomenon where an organism’s internal body temperature is largely determined by the external environment. In reptiles, this means that their bodily functions, including movement, are heavily influenced by ambient temperature, as they do not internally generate significant heat to regulate their temperature independently.

Temperature-Dependent Metabolism

The metabolic rate in reptiles is strongly influenced by the surrounding temperature. Colder conditions slow down metabolic processes, resulting in reduced energy production and decreased physiological activity, which in turn causes sluggish movement.

Enzyme Kinetics

Enzyme kinetics explains how the rate of enzyme-catalyzed reactions is dependent on temperature. At lower temperatures, the catalytic activity of enzymes diminishes, slowing down essential biochemical reactions that support muscle activity and overall movement.
