Metabolism

Cards (7)

  • Metabolism
    The sum of all the chemical reactions in a cell or the body
  • Respiration
    1. Releases energy from glucose
    2. Energy released is used by enzymes to synthesize new molecules in the cell
  • Glucose
    A really important chemical in metabolism
  • Conversion of glucose in plant cells
    1. Converted into cellulose which strengthens the plant cell wall
    2. Converted into starch which is a storage form of glucose
    3. Reacted with nitrate ions to make amino acids which are then used to synthesize proteins
  • Conversion of glucose in humans and other animals
    Converted to the molecule glycogen which is a storage form of glucose
  • Lipid synthesis
    1. One molecule of glycerol is reacted with 3 molecules of fatty acids to form a lipid molecule
    2. Lipids are found in the cell membrane
  • Protein breakdown
    1. Excess proteins are broken down into the chemical urea
    2. Urea is then excreted by the kidneys
