Effects of Sucrose Concentration On Cell Respiration In Yeast Abstract This lab investigates the effects of Sucrose concentration on cell respiration in yeast. Yeast produces ethyl alcohol and CO2 as a byproduct of anaerobic cellular respiration‚ so we measured the rate of cellular respiration by the amount of CO2 produced per minute. The results show a trend wherein increased concentrations of sucrose increase the rate of cellular respiration. Introduction All living cells require energy

Diffusion & Cell Size Lab Background The absorption of nutrients‚ excretion of cellular wastes‚ and the exchange of respiratory gasses are life processes which depend upon the efficient transport of substances into‚ out of‚ and throughout living cells. The process of diffusion can be easily visualized by adding a drop of blue food coloring to a glass of water. Initially‚ the food coloring remains in a small area in the water‚ dying it a dark blue. Over time‚ the molecules of food coloring

My major is earth and environmental studies‚ and I really care about some problems related to human and environment. To be honestly‚ I decided to choose “Over-consumption” to my persuasive speech topic as early as in the beginning of this semester. I felt I had responsibility to tell people the truth of the over-consumption and persuaded them to stop this bad situation‚ after I watched Greenpeace activist Annie Leonard’s video “story of stuff”. At the first time‚ I hesitantly think that this problem

Drinking is widely regarded as a socially acceptable practice and is embedded into the lifestyle of many cultures. In Australia alone‚ results from a 2015 survey reported that 86.4% of participants over the age of 18 consumed alcohol at some point in their life while 56.0% drank alcohol in the past month. It is possible for us to use alcohol safely. Many of us are able to control the amount of alcohol they drink and are known as recreational drinkers. They have the ability to refuse alcohol once

Cellular respiration is the process of breaking down chemical energy‚ most commonly glucose and oxygen‚ for use in the body as ATP with the release of water and carbon dioxide as bi-products (Mauseth‚ 2014). This process can be observed by careful analysis of the metabolic rate which is the total amount of energy released by an organism per unit mass. The respiratory quotient (R.Q) is the ratio of CO2 molecules lost per O2 molecules consumed which can be used to determine the efficiency of the metabolic

Antioxidant Effects on Reactive Oxygen Species Abstract Antioxidants are among key molecules for a healthy living. Antioxidants are molecules that prevent damage of cells through inhibition of oxidizing agents such as free radicals. This experiment was aimed at investigating the role of antioxidant on the inhibition of reactive oxygen species. To demonstrate this‚ quercetin was used as antioxidant and its effect on reactive oxygen species examined. RAW 264.7 cells
