The purpose of this investigation is to compare the ability of two different strains of yeast to respire, when using different sugars as respiration substrates. Considering the lengths that have been reached to develop varieties of yeast with greater suitability and effectiveness for very particular fermentation purposes, it seems reasonable to suppose that two different strains of the same species of yeast, selected for their different fermentation properties, have developed requirements that are not uniform. As a result of the…...

Aim: To investigate the effect of temperature on the rate of respiration in a suspension of yeast Saccharomyces cerevisiae. Background Knowledge: Yeasts are a form of eukaryotic microorganisms classified in the kingdom Fungi, with approximately 1,500 species known. They reproduce asexually by budding mainly, although some species reproduce by binary fission. They are unicellular, although some species with yeast forms may become multicellular due to way in which they normally reproduce. Typically the size of a yeast cell is approximately…...

Enzymes are the tools of life. They do almost everything in a cell. Virtually every one of life's chemical reactions is driven by some enzyme. Enzymes are organic catalysts that work like a starter on a car. With a small input of energy from the starter, a car can run on its own energy all day. They don't get not used up or changed when they "jumpstart" another molecule. They can perform the same task over and over working very…...

Microbes Anaerobic respiration happens in yeast and some germs, producing ethanol and carbon dioxide. They have been used in the making of lots of foods such as bread, yoghurt and vinegar, Lactic acid bacteria are the key component in yogurt production as they initiate the fermentation process. A lot of the types used in yogurt offer added health benefit to those who consume them routinely and are typically referred to as probiotics. Probiotics are thought to reinforce your body immune…...

Cellular respiration is a metabolic process where the body uses organic molecules to produce energy. One of the greatest energy sources that our body uses is glucose. In cellular respiration glucose is broken down, and the energy from those bonds is used to create adenosine triphosphate (ATP). There are two types of respiration: aerobic and anaerobic. In aerobic respiration there are 3 main steps: Glycolysis, Krebs Cycle (Citric Acid Cycle), and Oxidative Phosphorylation. In anaerobic respiration you can have alcohol…...

Abstract Carbon dioxide is a waste product of yeast respiration. A series of experiment was conducted to answer the question; does temperature have an effect on yeast respiration? If the amount of carbon dioxide is directly related to temperature, then varying degrees of temperature will result in different rates of respiration in yeast. The experiment will be tested using yeast and sugar at different water temperatures. I predict the warm temperature will be optimal for yeast respiration therefore the most…...

Apart from substrate concentration, which I will be changing in this experiment, it is important to keep the other variables the same to ensure the results are reliable and to get a fair test – results must change because of a difference in the input variable, not because of a different variable. I can monitor the temperature and check it stays the same by using a thermometer. I can keep the pH the same by always using water from the…...

Purpose Name Due Date Clothespin Lab / Muscle Fatigue What are the affects of anaerobic respiration on you muscles? Background Normally, muscles use oxygen through a process known as cellular/aerobic respiration to make energy (or ATP) from sugar (glucose). This process is very efficient and produces 38 ATPs for each molecule of glucose. Carbon dioxide and water are the results of this reaction. When muscles undergo rigorous exercise they require more oxygen to make ATP than the blood can supply.…...
