via the beta-oxidation pathway. Fats are used as the body does not require energy to be released rapidly until the point when the athlete achieves a relatively stable “metabolic pace.” The production of ATP is quicker from glucose than from fatty acids though‚ from anaerobic respiration. By 5 minutes once the athlete gets settled into a steady pace‚ aerobic pathways begin to take over. This aerobic pathway involves the catabolism of glucose‚ as a fuel. Reliance on glucose is due to the ability to

break it down into carbon dioxide‚ water‚ and energy required for the body to function. More scientifically‚ it is a three-step pathway that produces ATP (adenosine triphosphate.) The three stages of cellular respiration are: glycolysis‚ the citric acid cycle‚ and electron transport. Ethanol is a volatile‚ colorless liquid and is considered a psychoactive drug. Ethanol is generally known to have depressant effects on the central nervous system. If you subject mealworms to a 95% ethanol solution

Study of Krebs cycle using Mitochondria from Mung Bean Seedlings INTRODUCTION The mitochondria is a very important organelle in the plant cell because it carries out very important cellular reactions in the cell like the Krebs cycle and oxidative phosphorylation which is how the plants produce ATP from the pyruvate produced through glycolysis (Meyer and Millar‚ 2008). Glycolysis produces a net of 2 ATP for the plant which is not enough for the cell to function while the Krebs cycle and electron

Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

proteins that trigger activation of caspase family proteases and alteration of cellular reduction-oxidation (redox) potential (Reed and Green‚ 1998). Succinate dehydrogenase (SDH) and malate dehydrogenase (MDH) are enzymes that play a role in the Citric Acid Cycle portion of cellular respiration and are investigated further in this experiment. The purpose of this experiment was to prepare whole as well as broken preparation of mitochondria and compare the enzymatic activity of succinate dehydrogenase

the Krebs cycle‚ and electron transport. I would like to focus on the two common pathways; glycolysis and the Krebs cycle. Glycolysis is a series of reactions that convert glucose into pyruvate and help with the production of ATP. This process is anaerobic‚ which means that oxygen is not present‚ nor is it needed. The reactions happen within 3 phases and a total of 10 steps. The first phase of glycolysis is sugar activation. This is where the glucose is converted into 2 pyruvic acid molecules

glucose. Cells are broken down into simple food molecules. Cellular Respiration undergoes two processes: Glycolysis and The Krebs Cycle. In Glycolysis enzymes help in chemical reactions that break down oxygen and glucose into different molecules. Pyruvic and 2 molecules of ATP are produced during Glycolysis. In the Krebs cycle nine reactions occur. Pyruvic acid is broken down and carbon dioxide and energy are given off. This energy is then used to create ATP and water. 5. Why are photosynthesis
