Temperature and Yeast Fermentation
Saccharomyces cerevisiae, commonly known as baker’s yeast, is an key ingredient used mainly when baking bread or making alcoholic beverages. The main role of the...
Yeats Fermentation Lab
Investigative Question: How does the sugar concentration affect the fermentation of yeast?
The percentage of sugar in a solution is directly proportional to the amount of produced CO2, as a result of Yeast fermentation.
Amount of CO2 m...
Examining the Effects of Mass and Type
Of Sugar on Yeast Fermentation Lab
Purpose: To measure and analyze the effects of various types and masses of sugar in an ethanol fermentation reaction with yeast.
Ethanol fermentation is a system in which hydrogen ions...
IB Biology Internal Assessment: Yeast Fermentation Rates
Question- Growth: What is the effect on Yeast Growth/Expansion during fermentation when mixed in water of varying temperatures?
Hypothesis- Temperatures above or below the recommended fermentation temperatures will...
Yeast cells explanation of respiration hence colour change etc
Low temp colour change should be visible as the yeast cells are not necessarily dead, just inactive.
Activity increases from 20-45 c
High rate around 30-40
Starts to slow down basical...
Effects of Molasses Concentration on Yeast Fermentation
The purpose of this lab was to determine how yeast cells are affected by the concentration of a food source, and for our purposes, the food sources were corn syrup and molasses. Our hypothesis was that the yeast cells would ferment...
Living organisms catabolize organic molecules within their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve ox...
Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose
In our lab this week we tried to see how different amounts of substrates affect our organism, yeast, in its fermentation process. Yeast...
Cellular respiration is defined as an enzyme mediated process in which organic compounds such as glucose is broken down into simpler products with the release of energy (Duka, Diaz and Villa, 2009). It is a series of metabolic processes and oxidation-reduction reactions. Oxidation of substrates, su...

The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast, smith fermentation tubes and different substrates namely, starch, lactose, sucrose, glucose and fructose, which are from different kinds of carbohydrates, ranging from...
The purpose of this experiment is to determine the effect that temperature has on the growth and respiration of yeast fermentation. The growth and respiration of the yeast can be determined by using a glucose/ yeast solution mixed with water in flasks set at different temperatures. Ye...
THE EFFECT OF INHIBITORS AND MANIPULATION IN ENERGY PRODUCTION OF YEAST CELLS FOR GLYCOLYSIS AND FERMENTATION
The aim of this experiment was to study the process of alcoholic fermentation in Saccharomyces cerevisiae (yeast cells) and measure the rate of Co2 production during anaer...
I am going to try and measure the rate of respiration in yeast and find out what factors affect the rate of respiration. I am going to change the concentration of the glucose solution and I’m going to measure the volume of gas produced during respiration in cm³.
Factors Affecting Fermentation of Glucose by Yeast
Fermentation is anaerobic respiration whereby food is altered into more simple compounds and energy in the form of chemicals is produced, an example being adenosine triphosphate (biology-online.org/dictionary/Fermentation). All th...

Question: Which type of carbohydrate, glucose, sucrose, or starch, will produce the greatest amount of...
Effect of varying Temperatures on Enzymatic Activity of Bacterial and Fungal Amylase and hydrolysis of Starch
This experiment consisted of setting up a control group of starch in various temperature and then placing both fungal amylases and bacterial amylases in a mixture of starch an...
