Kerboodle Glossary
| Term | Definition |
|---|---|
| Active site | Part of an enzyme where reactants bind |
| Adult stem cells | Stem cells that are found in adults that can differentiate and form number of cells |
| Aerobic respiration | Exo reaction where glucose is broken down using O to make CO2 and H20 and release energy for the cells |
| Alleles | Dif forms of the same gene |
| Alveoli | Tiny air sacs in lungs that increase SA for gaseous exchange |
| Amino acids | Molecules made of C, H, O, N that are the building blocks of the exchange |
| Amylase | Enzyme that speeds up digestion of starch into sugar |
| Anaerobic respiratiom | Exo reaction where glucose is broken down into the absence of O to make lactic acid in the animals and ethanol and CO2 in plants and yeast. Small amount of energy for cells. |
| Arteries | Blood vessels that carry blood away from heart. Usually carry oxygenated blood and have a pulse |
| Asexual reproduction | One individual and the offspring is identical to the parent. No fusion of gametes or mixing of genetic info |
| Atria | Upper chambers of heart |
| Bacteria | Single-celled prokaryotic organisms |
| Benign tumours | Growths of abnormal cells that are contained in one area, usually within a membrane, do not invade other tissue |
| Bile | Neutralises stomach acid to give a high pH for the enzymes from the pancreas and small intestine to work well. Not an enzyme |
| Biodeversity | A measure of the variety of all the different species of organisms on earth |
| Cancer | Common name for a malignant tumour, formed as a result of changes in cells that lead to uncontrolled growth and devision |
| Capillaries | Smallest blood vessels. Run between individual cells, one cell thick walls |
| Cell membrane | Controls what moves in and out of the cell |
| Cell wall | The rigid structure and plant and algal ells. It is made of cellulose and strengthens the cell |
| Cellulose | Complex carbohydrate that makes up plant and algal cells and gives them strength |
| Chlorophyll | The green pigment contained in the chloroplasts |
| Chloroplasts | The organelles in which photosynthesis takes place |
| Community | Group of interdependent living organisms in an ecosystem |
| Coronary arteries | The blood vessels that supply oxygenated blood to the heart |
| Cytoplasm | Water-based gel in which the organelles of all living cells are suspended and most of the chemical reactions take place |
| Denatured | The breakdown of he molecular structure of a protein so it is no longer functions |
| Diffusion | The spreading out of the particles of any substance in a solution, or particles in a gas, resulting in a net movement of higher to lower concentration |
