the mitochondria. Aerobic respiration provides a lot of energy needed per molecule of glucose (the level of ATP produced can be as high as 38 ATP molecules per 1 molecule of glucose. When the body is exercising intensely respiration happens faster and the muscles need more oxygen. Anerobic respiration uses a reaction of glucose and water to make energy it creates by-products of water and carbon dioxide (glucose + oxygen → carbon dioxide + water (+ ATP or C6H12O6 + 6O2 → 6CO2 + 6H2O) There will come

UNKNOWN LAB REPORT UNKNOWN NUMBER 54 Ron Williams 7-28-05 Bio 205 Prof. Curlee Fall 2005 Purpose There are many reasons for knowing the identity of microorganisms. The reasons range from the knowing the causative agent of a disease in a patient‚ so as to know how it can be treated‚ to knowing the correct microorganism to be used for making certain foods or antibiotics. This study was done by applying all of the methods that have been learned so far in the microbiology laboratory

Intro: Carbohydrate‚ any of a large group of compounds in which hydrogen and oxygen‚ in the proportions in which they exist in water‚ are combined with carbon; the formula of most of these compounds may be expressed as Cn(H2O)n. Structurally‚ however‚ these compounds are not hydrates of carbon‚ as the formula would seem to indicate. Carbohydrates‚ as a class‚ are the most abundant organic compounds found in nature. They are produced by green plants and by bacteria using the process known as photosynthesis

should be negative and is not a protein. In the second experiment to test for glucose with the Benedict reagent sugar should be positive for glucose. Starch mixed with the Benedict reagent is probably positive for glucose because it is a polysaccharide. Onion juice mixed with Benedict reagent is probably positive for glucose because it is a fructose. Distilled water with Benedict reagent should be negative for glucose. The third experiment to test for starch using with and without the IKI reagent

absorbs the light and turns it into chemical energy. The plant then uses this energy to carry out photosynthesis. In humans chemical energy found in food is absorbed by the body’s cells during respiration to produce energy. The process of respiration Glucose + Oxygen → Carbon Dioxide + Water + Energy (C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP) This type of respiration is called aerobic respiration which means respiration with oxygen. Mitochondria carry out respiration in the cells. This is why muscles have so

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 the amount of the CO2 evolved

which occurs because of the high blood sugar levels. High blood sugar levels result in an overflow of glucose from the kidneys‚ carrying the fluid along with it. Because there is a constant loss of body fluid through urination there is a constant thirsty feeling (polydipsia). Diabetes is usually accompanied by sudden weight loss‚ due to the body not being able to utilize the available glucose to generate energy. This can result in the individual being hungry throughout the day (polyphagia)‚
