Metabolic Capacity

selected references

Catabolic metabolism provides the energy (ATP) that is essential for normal organism function, and in endotherms it also produces heat necessary for thermoregulation. However, many birds and mammals do not regulate their body temperature metabolically during development, even after birth or hatching. We are investigating changes in enzyme kinetics and gene expression to understand the development of metabolic capacity and, hence, endothermy.
