<p>A detailed PowerPoint of slides outlining kidney structure and function. Separate sections focus on ultrafiltration; reabsorption in the proximal convoluted tubule; water reabsorption in the Loop of Henle; and the role of the hypothalamus and posterior pituitary in releasing anti-diuretic hormone (ADH) and its affect on the permeability of the collecting duct in osmoregulation.</p> <p>Also included:</p> <ul> <li>Labelling excretory system activity sheet</li> <li>Information Sheets on the Kidney and it’s function</li> </ul>

<p>A collection of slides, past paper questions and worksheets on the Enzymes topic at A-level Biology.<br /> This includes:</p> <ul> <li>Enzyme Activity (Induced Fit &amp; Lock and Key Models)</li> <li>Factors Affecting Enzyme Activity</li> <li>Enzyme Inhibitors</li> <li>Biomarkers &amp; Biosensors</li> <li>Immobilised Enzymes</li> </ul>

<p>These powerpoints include the following topics within the GCSE Ecology Unit:</p> <ul> <li>Food Chain and Webs</li> <li>Sampling</li> <li>Factors affecting distribution</li> <li>Global Warming</li> <li>Decomposition</li> <li>Carbon &amp; Nitrogen Cycles</li> <li>Pyramids of Number &amp; Biomass</li> <li>Eutrophication</li> </ul> <p>There is a pupil booklet to go allow with this Ecology Unit.</p> <p>Hope these resources come in helpful.</p>
