Maintining a balance Module 1

Module 1 Discussion

This module describe what homeostatic processes are and what they do (enzymes, what is homeostasis and feedback).

____________________________________________________________________________________________________________________________________________________________________________________________________ Identify the role of enzymes in metabolism, describe their chemical composition and use a simple model to describe their specificity on substrates

Identify the pH as a way of describing the acidity of a substance

Explain why the maintenance of a constant internal environment is important for optimal metabolic efficiency.

Describe homeostasis as the process by which organisms maintain a relatively stable internal environment

Explain that homeostasis consists of two stages - detecting and counterbalancing.

Outline the role of the nervous system in detecting and responding to environmental changes

Identify the broad range of temperatures over which life is found compared with the narrow limits for individual species

Compare responses of named Australian ectothermic and endothermic organisms to changes in the ambient temperature and explain how these responses assist temperature regulation

Identify some responses of plants to temperature change
