patients that develop clinical signs of infection. Unlike other diseases sepsis is not diagnosed by the location or type of microbe involved in the infection. Some of the criteria used to diagnose sepsis are abnormalities of body temperature‚ pulse‚ respirations‚ and white blood cell counts. Some symptoms that are common in septic patients are fever‚ hypothermia‚ heart rate greater than 90 beats per minute‚ altered mental status‚ swelling of the extremities‚ and high blood glucose in diabetic patients

how starch and cellulose are treated to allow them to be used by the yeast? One potential ethanol feedstock is starch. Starch molecules are made up of long chains of glucose molecules. Thus‚ starchy materials can also be fermented after breaking starch molecules into simple glucose molecules. Examples of starchy materials commonly used around the world for ethanol production include cereal grains‚ potato‚ sweet potato‚ and cassava. A great amount of ethanol fuel is currently produced by starch

system‚ respiratory system and muscles are affected. Short term effects are immediate and long term refers to our adaptation to exercise. After an intense exercise we are still breathing heavily‚ that is due to our internal respiration taking in more oxygen or cellular respiration (where the cells converts the food into energy or releases the molecules of Carbon‚ Hydrogen‚ Oxygen and Nitrogen which make up our food and are stored to higher cells known as ATP or Adenosine Triphosphate). There are

the cells. They’re two types of metabolism which are Catabolism (Aerobic Metabolism) and Anabolism (Anaerobic Metabolism). Catabolism (Aerobic Metabolism) occurs when there is plentiful supply of glucose and oxygen for the cells to use for cellular respiration (Aerobic Respiration happens eventually with the mitochondria in the cells producing A.T.P-Adenosine Triphosphate). Anabolism (Anaerobic Metabolism) will occurs after vigorous exercise when demand for glucose and oxygen cannot be met by the

(Aerobe-Organisms that require oxygen for cellular respiration.) Aerobic respiration is a characteristic of eukaryotic cells‚ even though prokaryotic cells can use aerobic respiration as well. Helps produce allot of ATP. Example: Kreb’s Cycle. Anaerobic: Doesn’t require oxygen to survive and perform life functions. (Anaerobe-Organisms that don’t require oxygen to live) Anaerobic respiration occurs in mitochondria. Prokaryotes are capable of anaerobic respiration. Doesn’t produce allot of ATP‚ hence
