Abstract 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 simplest sugars glucose and fructose to the polysaccharide starch and water as the control‚ the hypothesis was tested. With the span of thirty minutes with five-minute intervals‚ the height of carbon dioxide

Goldfish Respiration Abstract The purpose of this experiment is to tests the effects of temperature on the respiration (breathing) rate of goldfish. In order to determine the goldfish respiration change adding small amounts of crushed ice to the water‚ than behavior will be noted. Then‚ the goldfish will experience the same experiment four more times and be noted again. This experiment will be conducted with four students‚ one goldfish‚ a 250 mL and a 150 mL beaker‚ thermometer‚ crushed ice‚

Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

Purpose: To determine the effect of various factors on the rate of reaction between an enzyme andits substrate‚ and also to determine the optimal ranges under which the enzyme activity ismaximized. Also to determine whether saline and alcohol are inhibitors or activators Hypothesis: PH factor prediction: I predict that as the pH increases so the activity of the enzyme willincrease until it reaches optimum pH range (pH 7) because the enzyme is less denaturedwhen it reaches the preferred pH level

Comparing the Rate of Fermentation of Yeast in Solutions with Different Concentrations of Glucose Brandon Bosley BIO 121 11/19/2013 Introduction: In our lab this week we tried to see how different amounts of substrates affect our organism‚ yeast‚ in its fermentation process. Yeast (Saccharomyces cerevisiae) is an organism that is cultured for the cells themselves‚ as well as the end products that they produce during fermentation. Yeasts are commonly known for the ethanol fermentation due

LAB REPORT Lab #9- Yeast Fermentation Dates of performed work: 3/26/18 Date submitted: 4/23/18 Abstract Yeast are unicellular fungi which act as facultative anaerobes. This means that yeast is able to produce ATP by aerobic respiration while oxygen is present‚ but are also capable of anaerobic respiration if oxygen is not available. This is called fermentation.

This isone-factor interest rate modeling. q The model will allow the short-term interest rate‚ the spot rate‚ to follow a random walk. This model leads
