ial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose). After a warm water bath‚ Sarkosyl detergent‚ toluene and ONPG were added to the tubes and incubated again. The data was qualified by observing the color change from clear to yellow to indicate the presence of lactase. The resu

respiration? The raw materials are glucose and oxygen. 3. What is the simple reaction for cellular respiration? C6H12O6+6O2=6CO2+6H2O+Energy 4. Why is it not practical for an organism to release all of the energy in glucose at once? There wouldn’t be any energy left to repeat cellular respiration and create more energy. 5. List and briefly describe the events of the stages of respiration? Glycolysis is where glucose is split into two molecules of 3-carbon

occurs to break down the stored nutrients for the body to use. Glycolysis is the catabolic process in which glucose is converted into pyruvate via ten enzymatic steps. There are three regulatory steps‚ each of which is highly regulated. There are two phases of Glycolysis. The first is known as the "priming phase‚" because it requires an input of energy in the form of 2 ATPs per glucose molecule. The second phase is known as the "pay off phase‚” because energy is released in the form of 4 ATPs‚

that facilitates the transfer of glucose from the blood into cells. Insulin lowers blood sugar by stimulating the liver to store glucose as glycogen. The release of insulin is nutrient-regulated – it is typically released after a meal. Glucagon: The release of glucagon is nutrient-related; typically released when blood sugar drops‚ during times between meals. (HINT: Think glucose-gone for glucagon.) Glucagon stimulates the liver to break down glycogen into glucose and release it back into the

is an example of a substrate? Lactase Lactose → Glucose + Galactose a. Lactose 2. During photosynthesis‚ plants use light energy to synthesize glucose from carbon dioxide. However‚ plants do not use up energy during photosynthesis; they merely convert it from light energy to chemical energy. This is an illustration of: a. The first law of thermodynamics 3.

In presence of simple sugars‚ the blue solution changes color to either green‚ yellow or brick-red‚ depending on the amount of sugar. Method 1) Mix smalls amount of each food sample (i.e.‚ Egg lumen‚ cylindrical piece of potato tuber‚ bread crump and crisps) in different test tubes with distilled water to make a

Background information: Heart rate : Heart rate is the number of time a persons heartbeats per unit of time‚ usually measured in BPM (beats per minute). Heart rate is measured by finding the pulse on body‚ usually taken from carotid artery‚ which supplies blood to the head and the neck and radial artery‚ which Is located on your wrist below your thumb
