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

FRQ #3 a) The flow of genetic information from DNA to protein in eukaryotic cells is called the central dogma of biology. The role of RNA in protein synthesis is extremely important as protein synthesis could not occur without RNA. Three forms of RNA exist solely to create proteins. Through a process known as translation‚ RNA constructs the proteins necessary to sustain life. Spliceosomes Process pre-mRNA by splicing out intronic nucleic acids producing mRNA which is then translated to protein

Biology What is cholesterol? Cholesterol‚ a waxy substance produced by the liver and found in certain foods‚ is needed to make vitamin D and some hormones‚ build cell walls‚ and create bile salts that help you digest fat. our liver produces about 1‚000 milligrams of cholesterol a day‚ enough cholesterol for the body to be ok without food with colesterol but it’s hard to avoid cholesterol entirely because so many foods contain it. Consequences o high cholesterol. Too much cholesterol in the

What is the aim of the study? [1 mark] The aim of this study is to modify knowledge of genes and enzymes for carotenoid biosynthesis in plant and also put some light on the challenges that are currently being faced by plant developmental biology and biotechnology. What is the author’s hypothesis? Was it supported or refuted by their research? [2 marks] The author’s hypothesis was that‚ “ Carotenoids protect photosynthetic organisms against potentially harmful photooxidative processes

Cycles in Biology Cycles in biology play a fundamental role in the world that we live in. Cycles occur all around and inside of us in many different forms‚ from the Krebs to the Calvin cycle. There are large scale cycles happening and they are essential in regulating the nutrients and substances that are around us which without‚ life on earth could no function. One of the largest cycles that occurs all around us is in everyday life is the carbon cycle. The current atmospheric
