Pea Respiration Lab:
This lab demonstrated how germinating seeds respire and need to consume oxygen in order to keep growing. Germinating seeds have a higher respiratory rate than non-germinating seeds. Cellular respiration allows organisms to release the energy stored in the chemical bonds of glucose.
Liver Enzyme Lab:
The lab demonstrated how an enzyme catalyzes a reaction and what can influence rates of catalysis. Enzymes are proteins that increase the rate of biological reasons. They accomplish this by lowering the activation energy of the reaction. Enzymes have optimal temperature and pH ranges at which they catalyze reactions. Enzyme concentration can also influence the rates of the reaction.
Diffusion and Osmosis Lab:
The lab shows the process of diffusion and osmosis in a semi-permeable membrane. Osmosis is the movement of water across a semi-permeable membrane from a region of high water concentration to a region of low water concentration. Water moves from a hypotonic region (low solute concentration) to a hypertonic region (high solute concentration).
