affect the rate of chemical reactions. The main purpose of enzymes in cellular respiration is to help in transporting electrons from one molecule to another. These transfers are called redox reactions. Where the loss of electrons from one molecule oxidation must correspond with more electrons to another substance known as reduction. Factors that would affect enzymes would be PH‚ temperature‚ enzyme concentration‚ substrate concentration. Glycolysis is the first step in cellular respiration and it means

microorganisms. The sludge is largely converted to ’biogas’‚ a mixture of CH4 and CO2‚ which is used to generate electricity for the plant. The liquid is treated by bacteria which break down the organic matter remaining in solution. It is then sent to oxidation ponds where heterotrophic bacteria continue the breakdown of the organics and solar UV light destroys the harmful bacteria. The role of the laboratory A wide variety of analytical tests are used to determine the purity of the wastewater at various

their cells and use the energy released to manufacture ATP by phosphorylating ADP. Many prokaryotes and virtually all Eukaryotes phosphorylate ADP either through fermentation (anaerobic) or respiration (aerobic). Both of these processes involve oxidation of foodstuffs‚ yet only the latter requires oxygen. Cellular respiration is a very complex process that consists of many steps that take place inside the cell‚ in an organelle called a mitochondrion. Mitochondria are responsible for converting digested

Discuss different strategies for producing wine with low or no SO2. Is there global demand from consumers for such wines? SO2‚ sulfur dioxide has been considered as one of the essential additives for making sound wine‚ which acts as antioxidant and antiseptic. History of sulfur in wine dates back to Roman times when they discovered that wine was kept fresh by burning sulfur candles inside empty wine vessels. However‚ the number of wines produced with low or no SO2 is increasing in these 10 years

AP Chemistry Final Exam Review ESSAY. Write your answer in the space provided or on a separate sheet of paper. 1) Explain the difference between a qualitative and a quantitative measurement. Provide examples to illustrate this difference. Answer: A qualitative measurement is a measurement that gives descriptive‚ nonnumeric results; a quantitative measurement is a measurement that gives definite‚ usually numeric results. "The rock is heavy" would be a qualitative measurement. "The rock weighs 110

The Rate Of Photosynthesis: Lab report 1) Construct a graph of your data 2) Using the graph‚ estimate the time at which 50 percent of the leaf disks were floating on the surface. The point at which 50 percent of the leaf disks are floating will be you point of reference for future investigations Using the graph the estimated time that roughly 50% of the leaf disks were floating on the surface was around the 10th minute. At the 10th minute our number rose up to

INTRODUCTION From natural gas‚ crude oils‚ and other fossil materials such as coal‚ few intermediates are produced that are not hydrocarbon compounds. The important intermediates discussed here are hydrogen‚ sulfur‚ carbon black‚ and synthesis gas. Synthesis gas consists of a nonhydrocarbon mixture (H2‚CO) obtain- able from more than one source. It is included in this chapter and is fur- ther noted in Chapter 5 in relation to methane as a major feedstock for this mixture. This chapter discusses
