proportional to the intense of the respiration process that was taking place (Doltar et al.‚ 249). This means that there was high rate of respiration at a temperature of 30°C test tube as compared with the other three test tubes. The optimum temperature for enzyme activity is usually between 35-37°C (Burchfield‚ 303). At this temperature the enzyme activity is maximum and thus the rate of respiration is very high at this temperature. This is the reason why the rate of respiration was very high at the range

Lab 8 Cellular Respiration and Fermentation Objectives: 1. Observe the effects of cellular respiration on temperature in a closed system. 2. Investigate carbon dioxide production in both germinating pea seeds and crickets. 3. Perform an investigative study of the rate of cellular respiration in both pea seeds and crickets at various temperatures. 4. Compare the alcoholic fermentation of glucose‚ sucrose‚ and starch by yeast. Introduction All organisms must have a continual

1. Define conquistador. What impact did conquistadores have on american indian societies? A conquistador is a spanish conqueror. The conquistadors exposed the american indian societies to diseases that they had no immunity to‚ causing thousands of natives to die. 2. What is the enlightenment?

Tyler Cowan Professor Foltz Biology 181 April 8th 2015 Lab Report: Respiration Abstract: The objective of this lab was to figure out which has a higher cell respiration rate between crayfish and elodea. In order to figure this out we first set up three beakers to represent our control‚ elodea and crayfish and filled them with 75mL of culture solution which were dechlorinated making the solution acidic. We then had to place both the elodea and the crayfish in separate beakers filled with 25mL of

W0Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is a way cells store food and energy‚ a catabolic pathway for the production of adenosine triphosphate (ATP). The cellular respiration happens in both eukaryotic and prokaryotic cells. The three stages are Glycolysis‚ Citric cycle‚ and electron transport. • What is the role

cannot be used as directly by cell as a source of energy so cells use ATP as their immediate source of energy. * This conversion of glucose into ATP takes place during cellular respiration and there are 2 different forms of cellular respiration depending upon whether oxygen is available or not * Aerobic respiration requires oxygen and produces CO2‚ water and lots of ATP. * Aerobic has 4 stages: 1) Glycolysis – the splitting of the 6-carbon glucose molecule into 2 3-carbon molecule

Cellular Respiration Lab Report Wednesday 8:00 A.M. Lab March 2nd‚ 2005 I. Introduction In this lab we are measuring the amount of oxygen used in both germinating and non germinating peas. We are measuring the oxygen consumption by taking a reading of a respirometer submerged in two water baths. The first bath will be cold water and the second warm to determine the effect of temperatures on oxygen consumption. Our negative control will be glass beads to measure to increase or decrease
