integration through hormones. In this chapter‚ you will learn about the neural system of human‚ mechanisms of neural coordination like transmission of nerve impulse‚ impulse conduction across a synapse and the physiology of reflex action. 316 BIOLOGY 21.1 NEURAL SYSTEM The neural system of all animals is composed of highly specialised cells called neurons which can detect‚ receive and transmit different kinds of stimuli. The neural organisation is very simple in lower invertebrates. For

Chemistry plays an important part in studying Biology. It answers some questions that Biology could not explain alone. Questions like: How does an organism convert foods for energy? How do plants use sunlight and water into all the things that cells needed to grow and reproduce? How does the basic unit of life passed through generation to the next? Here are some contributions of Chemistry in Biology: • Within atomic theory‚ chemistry contributes towards biology in the understanding of atoms and elements

Biology coursework: Substrate specificity in yeast AIM: To find out which substrate (glucose‚ starch‚ maltose‚ sucrose or lactose)‚ does yeast‚ the organism containing the enzyme‚ breaks down the quickest. Introduction: Usually‚ every enzyme has a specific substrate that is what we call the “lock and key” theory. We can try the reaction of an enzyme with different substrates and this enzyme will just work well with one of those substrates. One type of reaction catalyzed by enzymes is anaerobic respiration
