What this topic covers
Explain the significance of respiration, describing a simplified outline of chemical processes (glycolysis, Krebs cycle with ATP production). Deduce gaseous exchange and heat energy production during respiration from experimental setups. Describe respiratory organs and surfaces (body surface, gill, trachea, lungs, stomata, lenticel) and their organisms. Describe the mechanism for stomata opening/closing. Determine respiratory mechanisms in plants and animals. Examine oxygen's role in energy liberation and explain effects of insufficient oxygen on muscles. Use yeast cells and sugar solution to demonstrate fermentation and state the economic importance of yeasts.
