Title of Experiment: The Effect of Temperature on the Hatching Success of Brine Shrimps. Abstract In this experiment‚ 40 brine shrimp eggs are put into a test tube containing salt water at different temperature such as 25°C and 35°C respectively. The eggs are left from two days to hatch. After two days‚ the number of eggs successfully hatched are observed and counted. Introduction Brine shrimp is the common name for a primordial crustacean that reaches less than 1.3 cm in length and is usually

The Affect of Water Temperature on Goldfish Breathing Rate Carlos Vega Vanessa Santamaria Rasa Hodges 9/12/2013 Introduction The main objective of our lab was to see how temperature affects the breathing patterns of an Ectothermic animal. Ectothermic is the same thing as cold-blooded. It means that the animal‚ in this case a goldfish (Carassius Aauratus)‚ does not produce its own heat internally so the animals temperature depends on the temperature of its surroundings. So

Biochemistry CP2085 Effect of Temperature‚ Study and Measure of Enzymes Activity Abstract This experiment investigates the effect that temperature has on the rate of activity of enzyme β-galactosidase and also the rate of β-galactosidase activity in different concentration of substrate over time. Ο-nitrophenylgalactoside (ONPG) is used as a substrate for β-galactosidase. A spectrophotometer is used to detect the change in colour of the substrate. Results show that increase in temperature up to 50oC speeds

Abstract α-amylase was immobilized covalently on iron oxide magnetic nanoparticles. The synthesis of magnetic nanoparticles was done by the coprecipitation conventional method. The chemical composition and particle size of the synthesized particles was confirmed via X-ray diffraction. Tyrosine‚ Lucien and chitosan and glutaraldehyde were investigated to make a covalent binding between the iron oxide magnetic core and the immobilized enzyme. Immobilization using chitosan and glutaraldehyde show

are amylases? Amylases are enzymes that break down starch or glycogen. Amylases are produced by a variety of living organisms‚ ranging from bacteria to plants and humans. Bacteria and fungi secrete amylases to the outside of their cells to carry out extracellular digestion. When they have broken down the insoluble starch‚ the soluble end products such as (glucose or maltose) are absorbed into their cells. Amylases are classified based on how they break down starch molecules i. α-amylase (alpha-amylase)

Effect of Temperature ( C ͦ) on Enzyme Catalase Activity in potato Aim: To investigate the Effect of temperature (10‚ 37‚ 60) Celsius (C ͦ) on enzyme catalase activity in potato using 2% of hydrogen peroxide (H202) as the substrate measuring the height (cm) of oxygen gas (bubbles) and calculating the volume of oxygen bubbles produced (cm3) Introduction: Enzymes are biological catalysts that speed up metabolic reactions without being affected. They lower the activation energy needed to start

Aim: To find the effect of temperature on enzymes‚ using a potato as a catalyst. The source of catalase is in the potato cells. 2H2O2 → O2 + H2O Planning: Introduction: An Enzyme is any one of many specialised organic substances‚ composed of polymers of amino acids‚ that act as catalysts to regulate the speed of the many chemical reactions involved in the metabolism of living organisms Enzymes are classified into several broad categories‚ such as hydrolytic‚ oxidising‚ and reducing‚ depending

Aim: The aim of the experiment is to test the effect temperature has on the activity of the enzyme rennin. Hypothesis: I believe the rate of reaction will speed up as the temperature increases until it reaches about 37oC‚ which is the body temperature‚ where it will begin to slow down and stop reacting. I believe this will occur because enzymes have a temperature range at which they work best in and once the temperature goes out of this range the enzyme will stop working. Introduction:Enzymes are

The role of salivary amylase in the digestion of starches remains controversial. In the absence of pancreatic amylase‚ the key enzyme for starch digestion‚ salivary amylase may well represent a potential compensatory alternate pathway for the digestion of amylose‚ amylopectin‚ and glycogen. Clinically significant depression of pancreatic amylase occurs in chronic pancreatitis‚ pancreatic resection‚ pancreatic neoplasm‚ cystic fibrosis‚ and other causes of pancreatic insufficiency.
