Rate of Respiration in Yeast Aim: I am going to investigate the rate of respiration of yeast cells in the presence of two different sugar solutions: glucose, sucrose. I will examine the two solutions seeing which one makes the yeast respire faster. I will be able to tell which sugar solution is faster at making the yeast respire by counting the number of bubbles passed through 20cm of water after the yeast and glucose solutions have been mixed. Prediction: I predict that the glucose solution will provide the yeast with a better medium by which it will produce a faster rate of respiration. This is because glucose is the simplest type of carbohydrate (monosaccharide).
The Effect of Temperature on the Rate of Respiration in Yeast There are two types of respiration in yeast: Aerobic: [IMAGE] Anaerobic: Glucose [IMAGE] Carbon dioxide + ethanol + energy Respiration is controlled by enzymes, which are proteins which speed up one or more biological reactions. Within any cell many chemical reactions are going on at any one time. Yeast has many different types of enzymes that speed up respiration. Prediction I predict that as temperature increases, the rate will also increase, until a certain optimum temperature, after which, the rate will decrease until the rate is zero as respiration has stopped completely. Reason
Investigating the Effect of Substrate Concentration on Catalase Reaction. Planning -Aim : The aim of the experiment is to examine how the concentration of the substrate (Hydrogen Peroxide, H2O2) affects the rate of reaction. the enzyme (catalase).
Cellular respiration is a series of metabolic reactions, in which cells of most organisms carry out to produce energy. Yeast are single-celled organisms, classified in the Fungi family, that carry out this process, converting sugar, as a source of energy, and oxygen to create adenosine tripohosphate (ATP) for other chemical reactions. If the yeast cell is in a situation when oxygen is not present, the cell will undergo fermentation, which produces carbon dioxide and ethyl alcohol, aiding the baking of bread and making of wine.
· Add 2g of yeast to the water and add sugar (1g, 2g, …up to 5g).
The Effects of Concentration of Sugar on the Respiration Rate of Yeast Investigating the effect of concentration of sugar on the respiration rate of yeast We did an investigation to find how different concentrations of sugar effect the respiration rate of yeast and which type of concentration works best. Respiration is not breathing in and out; it is the breakdown of glucose to make energy using oxygen. Every living cell in every living organism uses respiration to make energy all the time. Plants respire (as well as photosynthesise) to release energy for growth, active uptake, etc…. They can also respire anaerobically (without oxygen) to produce ethanol and carbon dioxide as by-products.
The purpose of this investigation is to test the effects of multiple sugar substances on the respiration of yeast. Most people think of yeast when they think of what makes bread rise, cheese, alcoholic beverages, or other food products. Another type of yeast can also cause yeast infections, an infection of the skin. Yeasts (Saccharomyces) are tiny, microscopic organisms with a thin membrane and are usually oval or circular-shaped. They are a type of single-celled fungi of the class Ascomycetes, capable of processing sugar into alcohol and carbon dioxide (CO2 ) ; this process is known as fermentation. Fermentation and the products are the main focus points for this experiment being that cellular respiration of yeasts happens via the process of fermentation, which creates by-products of alcohol and CO2. The level of CO2 produced by the yeasts will show how effective each sugar substance is in providing cellular energy for the yeasts.

“Fermentation occurs in fruits, bacteria, yeasts, fungi, as well as in mammalian muscle”(Biology Online, 2008, p. xx-xx) . “Yeasts were discovered to have connection with fermentation as observed by the French chemist, Louis Pasteur” (Biology Online, 2008, p. xx-xx). “Pasteur originally defined fermentation as respiration without air” (Biology Online, 2008, p. xx-xx). “However, fermentation does not have to always occur in anaerobic condition” (Biology Online, 2008, p. xx-xx). “Yeasts still prefer to undergo fermentation to process organic compounds and generate ATP even in the presence of oxygen” (Biology Online, 2008, p. xx-xx). “However, in mammalian muscles, they turn from oxidative phosphorylation (of cellular respiration) to fermentation when oxygen supply becomes limited, especially during a strenuous activity such as intensive exercising” (Biology Online, 2008, p. xx-xx).
