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

What is the effect to the result of acceleration when you lower the height of ballistic ball? The effect to the result of acceleration when the height of ballistic ball was lowered was the result of acceleration increases based on the experiment every time the ballistic ball goes down. 2. What possible reasons

Knowing how to describe motion is an important first step in understanding the underlying physics that governs changes in motion. We see changes in motion all the time‚ as we go to work or school‚ participate in sports or even wander around our homes. If we never changed our own motion‚ we would never make it out of bed in the morning. The study

This study focuses on the effect that temperature has on the enzyme amylase. Enzymes are composed of proteins and acts as a catalyst to speed up the rate of a specific chemical reaction by lowering the activation energy. Reactions do not need enzymes to occur‚ but the human body and other living organisms depend on the use of enzymes in order for biochemical reactions to happen in milliseconds. Each enzyme contains a distinct three dimensional structure which is related to its particular function
