Cellular Respiration Through Alcoholic Fermentation

The experiment was conducted to determine the impact different yeast amounts had on yeast fermentation. It was hypothesized that the more yeast added the more CO2 would be produced. The carbon dioxide production was measured in the fermentation of yeast with solution of no yeast in test tube 1, 1mL yeast in test tube 2, and 3mL of yeast in test tube 3 over a period of twenty minutes. All of the yeast amounts produced CO2, but test tube 3 was the most efficient of the three. Introduction: This lab was to investigate fermentation, a cellular process that transfers the energy in glucose bonds to ATP. The energy in ATP can then be used to perform cellular work. Fermentation is…

Cellular Respiration and Rigor Mortis

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 fermentation or lactic acid fermentation. Overall, cellular respiration can be used in rigor mortis, which helps investigators determine the time of someone’s death. Aerobic respiration is used in the present of oxygen, and the first step in it is glycolysis….

Cellular Respiration in Sports

The Krebs cycle refers to a complex series of chemical reactions that produce carbon dioxide and Adenosine triphosphate (ATP), a compound rich in energy. The cycle occurs by essentially linking two carbon coenzyme with carbon compounds; the created compound then goes through a series of changes that produce energy. This cycle occurs in all cells that utilize oxygen as part of their respiration process; this includes those cells of creatures from the higher animal kingdom such as humans. Carbon dioxide is important for various reasons, the main one being that it stimulates breathing, while ATP provides cells with the energy required for the synthesis of proteins from amino acids and the replication of deoxyribonucleic acid (DNA); both are vital for…

Cellular Respiration

Abstract The effect of nature of substrates on the rate of cellular respiration in yeast was determined by using the Smith fermentation tube method. Mixtures of 15ml distilled H2O, 10% yeast suspension and 15ml of the following solutions (all at 10% concentration):1- starch, 2 – lactose, 3 – sucrose, 4 – glucose, 5 – fructose, 6 – distilled water , were poured in six smith fermentation tubes. Cotton balls were plugged in the openings of the tubes and the tubes were kept upright and observed for 30 minutes. The mixture with the sucrose solution acquired the highest computed volume of gas evolved and the rate of CO2 evolution seconded by glucose and followed by fructose. This stated that the higher…
