Cellular respiration is where stored energy is extracted from food, specifically glucose, through a process of metabolic reactions. This process begins in the cytoplasm with glycolysis, which breaks down 1 molecule of glucose into 2 molecules of pyruvate. Next, it goes to pyruvate oxidation (occurs in the mitochondrial matrix) where it takes the 2 pyruvates and oxidizes it to make the products of 2 acetyl CoA, 2 molecules of CO₂, and 2 NADH. Then it continues onto the citric acid cycle which goes

individual substances. There was a .31 grams difference and only a 3% error, meaning the final mass of 10.40 grams varied 3% from the original mass of 10.09 grams, which reveals that not much error was made in finding the mass of each substance. This lab applies to the real world in that it is useful for someone purifying water because he/she would know to filter it to separate the water from whatever substances are inside of it. Another application to the real world is if someone were to drop a metal

The goal of this experiments is to observe the relative trends of bacteria growth over time in broth. This experiment was conducted over the period of two days by observing the growth of bacteria in an agar broth. This solution was created by taken a single bacteria colony from a petri with an inoculation loop and placing into a bottle filled with an agar broth. After this, the bottle was placed in a incubator and left there for 24 hours. On day one, the bottle's Absorbance was measured using a spectrophotometer

Next, the mouth is a collection of the teeth, gums, hard palate, soft palate, tongue, tonsil, ulva, lips, et cetera. The mouth is a premier environment for bacteria to live because it has a warm climate. Also, when the hosts eats, they receive an appropriate amount of nutrients to survive. Following, to determine how many bacteria are in the mouth, researchers have measured the weight of all the bacteria on the teeth. The weight of the mentioned bacteria is 10 mg. But since the teeth are only 1/20

For the Identification of an Unknown Compound lab, the physical properties, along with the IR and the H1 NMR will be used to determine the molecular structure and identity of the unknown compound. For the physical properties, the smell, color, state, solubility and the refractive index will be used. Then, the IR and H1 NMR be obtained using the unknown compound given during the lab. The IR and H1 NMR will play a major role in determining the molecular structure of the compound because the stretches

the enzyme directly corresponds to the substrate to carry out a specific job. An enzyme is able to be used until it becomes denatured, or when the active spot of the enzyme changes shape due to high temperatures, or pH and salinity changes. In this lab, an important enzyme in animals called catalase, which is essential to catalyze the breakdown of Hydrogen Peroxide (H2O2), was tested. Hydrogen

The purpose of this experiment was to demonstrate how diffusion and osmosis moves across a dialysis membrane. The sub-purpose was to determine if the sucrose solution, that was in dialysis tubing would leak into the distilled water. The hypothesis states that if a sucrose solution, in dialysis tubing, is placed into a beaker filled with distilled water the net movement of sucrose will be into or out of the dialysis bag. The null hypothesis states that if the sucrose solution in a dialysis bags mass

Introduction In the northern hemisphere, many oak trees deriving from hundreds of species can be found. Oak trees come from the genus Quercus. The flowers produced on oak trees are known as acorns. The Flowering Dogwood tree can be found in eastern North America, and is known as genus Cornus Florida. The flowering dogwood tree produces loose circular fruit. In the experiment, the effects of climate on primary tree growth in different genus that originate from the same area were examined. Two different

Alcohol on Daphnia magna Yong Im El Centro College This experiment tested the effects of alcohol on the heart rate of Daphnia magna. We observed the heart rate of the D.magna in just water and compared it with the organism in a 5 percent alcohol solution. The results showed that the D.magna heart rate was decreased by 33 percent. The alcohol has an effect on the central nervous system. Introduction Alcohol is a common organic compound formed when a hydroxyl group (-OH) is substituted for a hydrogen

The effects on heart rate on a Daphnia Magna with varied substances William Piper WCCC/Spring 2015 Semester A&P 2 Dr. Sisak Introduction: The purpose of the experiment conducted was to test the effects of varied substances on the heart rate of a Daphnia Magna. A Daphnia Magna is a freshwater flea native to North America (Wikipedia, 2015). The substances used on the Daphnia were aspirin, nasal spray, Alka-Seltzer, coffee, and tea. Aspirin is a common pain reliever and fever reducer (Rx List,
