| Description | Key Word |
| A biochemical pathway that forms part of the light independent reaction of photosynthesis, during with CO2 is reduced to form carbohydrate | |
| A synapse that occurs between a Neurone and a Muscle | |
| A hormone produced by alpha cells of the islets of Langerhans in the pancreas that increases blood glucose levels by initiating the breakdown of glycogen | |
| Process of making many copies of a specific sequence of DNA or part of a gene | |
| Portions of DNA within a gene that do not code for a polypeptide. Removed from the pre-messenger RNA after transcription | |
| A sequence of 3 adjacent nucleotides in mRNA that codes for one amino acid | |
| The thick filamentous protein found in skeletal muscle | |
| Protein channels across a cell surface membrane that uses ATP to move sodium ions out of a cell in exchange for potassium ions which move in | |
| The maintenance of a more or less constant internal environment | |
| The breaking down of large molecules into smaller ones by the addition of water molecules | |
| Consequence of an increase in nutrients in fresh water lakes and rivers, often leads to a decrease in biodiversity | |
| A condition in which the alleles of a particular gene are different | |
| A more or less self-contained functional unit in ecology made up of all the interacting biotic and abiotic factors in a specific area | |
| The process linking glycolysis with the krebs cycle in which H and CO2 are removed from pyruvate to produce acetyl coenzyme A in the matrix of the mitochondria | |
| A detectable alteration in the internal or external environment of an organism that produces some change in that organism | |
| The first part of cellular respiration in which glucose is broken down anaerobically in the cytoplasm into 2 molecules of pyruvate | |
| Widening of the Internal diameter of blood vessels | |
| Part of the nervous system, controlling the muscles and glands, that is not under voluntary control | |
| A gene that maintains normal rates of cell division and so prevents the development of tumours | |
| A hormone produced by beta cells in the islets of langerhans in the pancreas, which decreases blood glucose levels by increasing the rate of conversion of glucose to glycogen | |
| A fatty substance that surrounds axons and dendrites in certain neurones | |
| A junction between neurones in which they do not touch but have a narrow gap, the synaptic cleft, over which a neurotransmitter can pass | |
| A plant adapted to living in dry conditions | |
| Any microorganism which causes disease | |
| Stage of photosynthesis which does not require light energy but does need the products of the LDR | |
| Mutated versions of proto-oncogenes that result in increased cell division. Normally resulting in a tumour | |
| A technique used to separate DNA fragments of different lengths by placing them on Agar Gel and passing a voltage across them | |
| Series of aerobic biochemical reactions in the matrix of the mitochondria of more eukaryotic cells by which energy is obtained through the oxidation of acetylcoenzyme A | |
| Change that Occurs in the electrical charge across the membrane of an axon when it is stimulated and a nerve impulse passes | |
