Fermentation: The Effect of Temperature Introduction Fermentation is a metabolic pathway that allows a cell to perform cellular tasks by shifting the energy in the glucose bonds to the bonds in ATP in the presence of less oxygen. Fermentation occurs to allow the process of Glycolysis to continue to produce ATP for the cell. In the process of fermentation, NADH is oxidized. Pyruvate directly gains the electrons from NADH, instead of the electrons going to the electron transport chain. To better

Using temperature as a way to describe a person has been understood as a metaphor, however studies have revealed that there is a connection between the association of warmth and feelings of social belonging (Ijzerman et al., 2012). The belief that our physical world has an influence on our cognition is called the embodiment theory (Chen, Poon & Dewell, 2014). In this theory it is believed that our surroundings shape of psychological feelings (Chen et al., 2014). Hence, why we use temperature as a

Unit 4: Heat and Temperature Topic A: Illustrate and explain how human needs have led to technologies for obtaining and controlling thermal energy and to increased use of energy resources. Investigate and interpret examples of heat-related technologies and energy used in the past (e.g. domestic and industrial purposes) Steam engines were the first engine type to see use in industrial purposes. A fire heats water which turns to steam and the steam then has the ability to move things. They were

don't take damage from the temperature and will remain at the normal and expected operating temperature.To do this the animal must consume energy from inside its body so that it can perform the act of maintaining homeostasis. This energy most often comes from

Effects of Temperature on Catechol Oxidase. Lania Ellis, 2014, 102 Student Center Dr. San Marcos, TX 78666. Temperature can affect the reaction of catechol oxidase by speeding up or slowing down the reaction. I was able to see what happened to the absorbance after changing the temperature of the catechol oxidase solution. I did this by heating and cooling the solutions to measure the absorbances in hot, cold, warm, and room temperature. Then the data was compared to see how the temperature effected

effect of temperature on a chemical reaction. Hypothesis: If the temperature (I.V.) of materials in the reaction are increased, the reaction time (D.V.) will decrease. Variables: In this experiment, the temperature (in degrees Celsius) of the chemicals is the independent variable. To change the temperature, the materials are placed in a bath of water being heated by a hotplate. The reaction time (in seconds) is the dependent variable of this experiment. This will be changed by the temperature of the

The Effect of Temperature on the Enzyme Peroxidase     The objective of this experiment is to explore the effect of temperature on the enzyme peroxidase. To comprehend the effect that temperature can have on enzymes, specifically peroxidase, one must understand what enzymes are and what their function is. Enzymes are proteins that are found in cells that function as catalyst (Ms. Chang's Enzyme Notes). What is meant by this is that enzymes increase the speed of chemical reactions without changing

Investigating the effect of temperature on plant cell membranes The purpose of this activity is: • to practise experimental and investigative skills • to investigate the effect of temperature on cell membrane structures Procedure SAFETY: Always carry scalpels clasped to a tile and with the tip pointing away from you. Beetroot cells contain pigments called betalains that give the tissue its dark purple-red colour. The pigment is contained in the cell vacuole. Investigation

in a bunsen burner until it completely phase changed into liquid. Then, we placed the test tube containing liquid pdB in cool tap water recording the temperatures of both the water and the pdB every 30 seconds until they were within 3°C of each other. After, we placed a test tube containing frozen solid pdB in hot tap water recording the temperatures of the pdB and the water every 30 seconds until they were within 3°C of each other. To finish the experiment, we graphed our data in one graph. The graph

constant temperature 1-2m from the entrance within four different habitats – open field, forested, short ground cover and sandy bank – during both summer and autumn. However, noticeable differences in the temperatures between the seasons were observed. Although, this was expected as the insulating properties of the soil stop daily, but not seasonal, fluctuations in temperature from a depth of approximately 0.30cm (Reichman & Smith 1990), with the main factors that did influence burrow temperatures being
