“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which…

Objectives: Observe the effects of cellular respiration on temperature in a closed system. Investigate carbon dioxide production in germinating pea seeds and crickets. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at different temperatures. Compare the alcoholic fermentation of glucose, sucrose, and starch by yeast. Ultimately, the…

Introduction This report discusses an experiment conducted to examine the rate of aerobic cellular respiration in aquatic organisms. The study focused on Elodea (an aquatic plant), snails, and goldfish. Carbon dioxide production was monitored as a measure of respiration. Each organism, being ectothermic, was placed in covered beakers resulting in varying amounts of carbon dioxide…

Describe the role of the citric acid cycle as a central metabolic mechanism. Explain what happens to the cells’ abilities to oxidize acetyl CoA when intermediates of the cycle are drained off for amino acid biosynthesis. Glucose is a source of energy that is metabolized into glycolysis to pyruvate yielding ATP. To become more efficient,…

Yeast is a singled celled fungus that contains protein and is part of the fermentation process. As explained in question nine, fermentation is the process of the breakdown of sugars by bacteria and yeast using a method of respiration without oxygen (anaerobic respiration). It involves a culture of yeast and a solution of sugar, producing…

Background Research Yeast are eukaryotic microorganisms Just like other organisms, they must respire in order to survive. Respiration can be defined as the controlled release of energy from organic compounds to form adenosine troposphere (TAP). The type of respiration that occurs is called aerobic respiration. It occurs when glucose and oxygen are present. It can…
