Lab 04: Sugar Respiration in Yeast Sugars are vital to all living organisms. The eukaryotic fungi‚ yeast‚ have the ability to use some‚ but not all sugars as a food source by metabolizing sugar in two ways‚ aerobically‚ with the aid of oxygen‚ or anaerobically‚ without oxygen. The decomposition reaction that takes place when yeast breaks down the hydrocarbon molecules is called cell respiration. As the aerobic respiration breaks down glucose to form viable ATP‚ oxygen gas is consumed and carbon

IB HL BIOLOGY Dialysis Lab: Exploring Osmosis and Diffusion Through A Membrane Introduction: Dialysis is the flow of certain solutes through a semi permeable membrane. Dialysis is usually used on patients with failing kidneys to clinically purify blood in their kidneys‚ or other regions of their bodies. The dialysate contains waste matter that flows from the blood our of the dialysis tubing. Question/aim of lab: To test the solutions inside and outside the dialysis tubing with Benedict’s

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air‚ but it is the Oxygen in the air which is necessary for aerobic respiration. Anaerobic respiration is in the absence of air. Here is a molecular model of a glucose molecule. You do not need to memorise the diagram for you GCSE exam‚ but it should help you to understand that a molecule of glucose contains six atoms of Carbon (shown in blue)‚ twelve
