Biology B4
  1. Enzymes
    1. Proteins produced by living things and speed up chemical reactions
      1. require the correct conditions
        1. Temperature
          1. Higher will speed up the reaction until it gets too hot
            1. changes shape of the substrate so it doesn't fit in to the active site - it's been denatured
          2. PH Level
            1. Interferes with the bonds holding the enzyme together. Changes the shape - Denatured
        2. Cells
          1. Similarities
            1. Nucleus - contains DNA (instructions for protein)
              1. Cyptoplasm - enzymes are made
                1. Cell Membrane - controls what goes in and out
                  1. Mitochondria - Aerobic respiration takes place
                  2. Differences - What Plant cells have
                    1. Cell wall
                      1. Vacuole
                        1. Chloroplasts
                        2. Bacteria (Simple Cell Structure)
                          1. NO Nucleus - DNA Floats around in the cyptoplasm
                            1. No mitochonrdia
                              1. can still respire
                          2. Respiration
                            1. Aerobic Respiration
                              1. releases more glucose per molecule than ->
                                1. Most common
                                2. Anaerobic Respiration

                                  Annotations:

                                  • NO OXYGEN
                                  1. when you do a lot of exercise, muscles don't have enough Oxygen
                                    1. Produces Lactic Acid
                                      1. can produce Ethanol
                                    2. Photosynthesis
                                      1. 6CO2 + 6H20 --> C6H1206 + 602
                                        1. plants use glucose
                                          1. 1) Respiration 2) Make Chemicals for Growth 3) Stored as starch
                                          2. 3 factors that effect it are
                                            1. Light intensity
                                              1. amount of CO2
                                                1. Temperature
                                              2. Diffusion, Osmosis & Active Transport
                                                1. movement of particles from a high concentration to a low
                                                  1. movement of water from a dilute to a more concentrated solution through a partially permeable membrane
                                                    1. movement of chemicals over a cell membrane from a lower concentration to a higher concentration
