  • What does amylase do?
    breaks down glycosidic bonds within starch molecules. Transforming complex carbohydrates into simpler sugars
  • mitochondria
    provides energy for the cell, site for aerobic respiration
  • Ribosomes
    makes protein for the cell, and protein synthesis
  • cell membrane
    controls what comes in and out of the cell
  • Cell wall
    support and structure for the cell, helps maintain the shape
  • Cytoplasm
    Jelly like substance where chemical reactions occur
  • vacuole
    large sac in the middle of the cell which contains cell sap
  • Chloroplast
    contains chlorophyll, where photosynthesis occurs
  • What happens to the active site when there is a reaction?
    The active site will bind to the specific substrate to start the reaction
  • proteins
    a large 3D molecule formed by a chain of amino acids. The 3D shape is formed by folding in the chain which depends on the sequence of amino acids
  • Factors that affect enzymes
    Temperature being above the optimum, increase in pH and concentration
  • Magnification
    The process of enlarging the physical appearance/image of something
  • Enzymes
    Known as biological catalysts. Increases rate of reactions and speeds them up.
  • Magnification Equation 

    image size/actual size
  • Differences between light + electron microscope
    electron has higher resolution + greater magnifaction so you can see a larger image and in more detail
  • Specialised cells
    Cells that have a specific function. Around 200 in the human body, Adapted to their functions.
  • Fertilisation
    Occurs in the oviducts of the female reproductive system. Cells in the lining of the oviduct transport egg cells (developing embryos) towards the uterus.
  • How are oviduct cells adapted?
    hair like cilia which waves from side to side to sweep substances along
  • nucleus
    controls the cell, contains DNA, genetic material and chromosomes
  • 3 things a plant cell has which an animal cell doesnt
    vacuole, chloroplast and cell wall
  • interphase
    DNA is copied
  • cytokinesis
    the cell divides in two
