• Organisms can be arranged into different groups based on the internal and external features they share
• Aerobic respiration is the series of chemical reactions in cells that uses oxygen to break down nutrient molecules to release energy.
• Glucose + Oxygen -> Carbon dioxide + water
• C6H12O6 + 6O2 -> 6CO2 + 6H2O
• Anaerobic respiration is the series of chemical reactions in cells that breaks down nutrient molecules to release energy without using oxygen.
• Glucose -> lactic acid
• C6H12O6 -> 2C2H5OH + CO2 (yeast- anaerobic respiration)
• Glucose -> alcohol + carbon dioxide (yeast)
• The variable you change is called the independent variable
• The variable you measure when you change the independent variable is called the dependant variable.
• The variables you keep the same are called control variables
• You can reduce the effect of random errors by taking a repeat reading and finding the mean. This will make the results more reliable.
• Make sure you're wearing sensible clothing in the lab. Safety goggles, gloves and a lab coat.
• Salivary Amylase (Carbohydrase)

  Made by the salivary glands

  Works in the mouth

  Breaks down starch into maltose
• Pancreatic Amylase (Carbohydrase)

  Made in the pancreas

  Works in the duodenum

  Breaks down starch into maltose
• Maltase (Carbohydrase)

  Made in the epithelial cells

  Works in the epithelial cells

  Breaks down maltose into glucose
• Pepsin (Protease)

  Made in the stomach

  Works in the stomach

  Breaks down protein into short chain amino acids
• Trypsin (Proteases)

  Made in the pancreas

  Works in the duodenum

  Breaks down short chain amino acids into single amino acids
• Lipase (Lipids)

  Made in the pancreas

  Works in the duodenum

  Breaks down lipids to fatty acids and glycerol
