Biology coursework The aim of this experiment is to investigate the affect of pH on the enzyme amylase. The amylase is used to break down the polysaccharide starch. Amylase is a digestive enzyme classified as a saccharidase (an enzyme that cleaves polysaccharides). It is mainly a constituent of pancreatic juice and saliva‚ needed for the breakdown of long-chain carbohydrates (such as starch) into smaller units. Amylase is also synthesized in the fruit of many plants during ripening‚ causing them

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

Biology Notes Genetics Trait - distinguishing characters or phenotypic features of an individual. (e.g. Blue eyes‚ black hair‚ etc.) Purebreed - having descended from ancestors of a distinct type or breed. Purebreed organisms in a given species or variety all share similar traits. (e.g. Purebred dog.) P Generation - Designation given to the parent generation. F1 and F2 generation - First and second filial generation. First Filial Generation - offspring from the cross of the P generation.

Biology 1500 Name: Chapter 10 Assignment 1. What is Genetics? The study of the way in which an individual’s traits are transmitted from one generation to the next. 2. What is heredity? Heredity is the tendency for traits to be passed from parent to offspring. 3. Why did Gregor Mendel choose garden peas to student for his experiments? Mendel chose to work with the garden pea because several of its characteristics made it easy to work with: many varieties were available‚ he knew

Biology project Measuring Light Intensity Soil moisture and soil pH meters are also available - both are used by simply pushing the probe into the soil and reading themeter. Errors can be made when measuring abiotic factors when the soil moisture or pH meter probes are not cleaned between readings. As always the results can be made more reliable by taking many samples. Here are some examples: Daisies The more light available‚ the more daisy plants will be present.0 This is because daisies
