Enzymes in Living Tissues Purpose: The purpose of the lab was to analyze the enzymes in living tissues‚ represented by the pieces of liver. Also‚ hydrogen peroxide was used to demonstrate these effects. Storyboard: Materials: 2 50 mL beakers 10 mL graduated cylinder 3% hydrogen peroxide solution Hot water bath Lemon juice or HCl Fresh liver Forceps Procedure: Measure 10 mL of hydrogen peroxide and record its temperature. Pick the liver up with the forceps and

CELL THEORY – STEM CELLS Stem cells are a large focus of study in today’s biomedical world. “They are cells that exist in an undifferentiated state‚ and transform into differing tissue types depending on what the cells surrounding them are‚“ (National Institute of Health‚ 2012). Stem cells have the remarkable potential to develop into many different cell types in the body during early life and growth. In addition‚ they also serve as an internal repair mechanism inside many tissues‚ dividing without
