Investigation into how pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product

Investigation of Water Potential in a Root Vegetable Introduction Background Information: Osmosis is the passage of water from a region of high water potential to a region of low water potential‚ down a water potential gradient through a semi-permeable membrane. If a plant cell‚ or an item with similar properties is put in water‚ three different things can happen: • If the surrounding area has a higher water potential‚ the cell will increase in mass through osmosis. The cell will

unit of the nervous system. These neurons work together with other excitable cells to produce action potentials when they receive electrical or chemical stimuli. Action potentials can be thought of as an “all-or-nothing” event and occur as a large-scale depolarization when sodium and other positive ions rapidly enter the neuron through membrane channel proteins. Once initiated‚ action potentials travel down the length of the axon and when it reaches the end a neurotransmitter is released into the
