| AP Cellular Respiration Lab Report Lab #3 Name Other Group Members: Name and Name Background Information Cellular respiration is the catabolic pathway that includes Glycolysis‚ Krebs cycle‚ and the Electron Transport Chain. The glycolysis and Krebs cycle portion of cellular respiration both use substrate-level phosphorylation while the electron transport chain uses oxidative phosphorylation. Cellular respiration can also include Alcohol or Lactic Acid
Free Cellular respiration Adenosine triphosphate
Fermentation is a metabolic pathway that produce ATP molecules under anaerobic conditions (only undergoes glycolysis)‚ NAD+ is used directly in glycolysis to form ATP molecules‚ which is not as efficient as cellular respiration because only 2ATP molecules are formed during the glycolysis. One type of fermentation is alcohol fermentation‚ it produces pyruvate molecules made by glycolysis and the yeast will break it down to give off carbon dioxide‚ the reactant is glucose and the byproducts are ethanol

Objectives for Lecture 9 Know the difference in resolution and magnification between light and electron microscopes. Understand the process of cell fractionation based on centrifugation and know what the purpose of cell fractionation is. Know what the differences in cell structure are between prokaryotic cells and eukaryotic cells Know that most eukaryotic cells are between 10-100 m in diameter‚ whereas most prokaryotic cells are about 1 m in diameter. Know the following terms‚ plasma

is anaerobic respiration‚ the production of lactate during which the muscles have a limited supply of oxygen‚ and however keep working despite this. Aerobic respiration requires oxygen and glucose present to work‚ and occurs in 4 stages: 1) Glycolysis- the splitting of a 6-carbon glucose molecule into 2 3-carbon pyruvate molecules. There is a net gain of 2 ATP’s produced. 2) Link reaction- the conversion of the 3-carbon pyruvate molecule into carbon dioxide and a 2-carbon acetyl co-enzyme

Seven Mystery Deaths Omesh Khemai Biology 1 Professor Depass 10.28.14 Case Study The first was a 12-year-old girl. Her parents said that she was awake in the middle of the night complaining of a stuffy nose and sore throat. They gave her an extra strength Tylenol and sent her back to bed. At 7am the next morning‚ the parents discovered that the girl had collapsed on the bathroom floor. An ambulance rushed the girl to a nearby hospital‚ where she was pronounced dead. That same day

Fructose is phosphorylated by the enzyme hexokinase to form fructose-6-phosphate‚ an intermediate of glycolysis. Diagrams of enzymatic activity As depicted in the diagram above‚ an enzyme acts a catalyst to lower the activation energy of a reaction. The enzyme’s conformation is such that the substrates easily bind to the enzyme and with the addition

from exertion or prolonged stress and the failure to maintain an expected power output. (Amussen) The process by which your body produces energy is called glycolysis. During glycolysis‚ glycogen is broken to produce creatine phosphate‚ which releases energy. The energy released catalyzes a reaction to produce ATP. The ending product of glycolysis is lactic acid‚ which is created by breaking pyruvate acid down. Then lactic acid is broken down to produce lactate. For each compound of lactic acid that

The Webster’s Dictionary defines calorimeter as‚ “an apparatus for measuring quantities of absorbed or emitted heat or for determining specific heats.” While direct calorimeters measure the amount of heat produced in a small chamber‚ indirect calorimeters measure the amount of heat produced by taking into account the amount of consumption of oxygen and elimination of carbon dioxide. Both contain the same concept‚ but have a different approach. Indirect calorimetry is the preferable way for physiologists
