Matthew Saldanha Bio DCP lab-Catalase experiment Aim: To investigate enzyme kinetics‚ using different concentration of the enzyme. Hypothesis: The assay system used in the lab consists of a filter paper disc coated with the enzyme and the dropped into a papercup of substrate (Hydrogen Peroxide). As the hydrogen breaks down the hydrogen peroxide into hydrogen and oxygen gas‚ the bubbles of oxygen gas collect underneath the filter and make it

affects its Fractional Loss of Kinetic Energy Research Question: What is the relationship between initial height of a drop and the fractional loss of kinetic energy in a bouncing ball? Introduction: When an object is held at a height above the ground‚ it possesses gravitational potential energy (Ep = mg∆h) that is directly dependent of the mass and height of which the object is positioned above the ground. When it is dropped‚ Ep is converted into kinetic energy (Ek = ½ mv2)‚ energy the

the Cobalt Used in Lithium-ion Batteries? In our modern world today‚ mankind’s surge in technological advances has made batteries a ubiquitous necessity in our daily lifestyles. The most popular form of battery is the lithium-ion (Li-ion) battery (Brain)‚ which is used an array of devices ranging from laptops and cellphones (Brain) to electric cars (Puiu). However‚ there is a need at the moment to develop a more sustainable and environmentally friendly lithium-ion battery. This is because the

A patient is admitted for electroconvulsive treatment (ECT). The physician orders the neuromuscular blocking agent metocurine iodide (Metubine) to reduce trauma by relaxing skeletal muscles. Explain the process of muscle contraction and how a neuromuscular blocking agent‚ such as Metubine‚ would interfere with muscle contraction. In order to understand how a neuromuscular blocking agent works one must first understand the process of muscle contraction and what has to take place in order for us

An investigation to find out what factors affect the rate of electrolysis of a solution containing copper (II) ions. Plan It is known that by passing a constant electric current through a copper sulphate solution the passage of ions through this solution results in copper atoms being dissolved into the solution from the anode‚ which has a positive charge while positive copper‚ ions (cations) are also being discharged at the cathode which has a negative charge. Normally anions‚ which have a negative

K. C4H8 (g) 2 C2H4 (g) The decomposition of cyclobutane follows first order kinetics as the unit of A is s-1. Comment: The units for A provide information on the reaction’s overall order of kinetics. Substitute the values of In A = 15.6 and Ea = 261 x 103 into the Arrhenius equation. k = 3.595 x 10-17 s-1 half-life = ln2/k = 1.93 x 1016 s (3sf) Example 5 Radioactive decay follows first order kinetics.
