Structure & Function of the Mitochondria Mitochondria are rod-shaped organelles 0.5 - 1.0 µm in diameter They are the site of aerobic respiration in eukaryotic cells The function of mitochondri...
Investigating RQs Respirometers are used to measure and investigate the rate of oxygen consumption during respiration in organisms They can also be used to calculate respiratory quotients The exper...
Respiratory Quotient (RQ) The respiratory quotient (RQ) is: the ratio of carbon dioxide molecules produced to oxygen molecules taken in during respiration RQ = CO2 / O2 The formula for the Respirat...
Energy Values of Respiratory Substrates Glucose is the main respiratory substrate for aerobic respiration in most cells When the supply of glucose in a cell has been used up a cell may continue res...
ATP: Universal Energy Currency Energy released during the reactions of respiration is transferred to the molecule adenosine triphosphate (ATP) ATP is a small and soluble molecule that provides a sh...
The Need for Energy Living organisms are composed of cells, and within each cell, many activities and processes are constantly being carried out to maintain life Work in a living organism requires ...
