Experiment 9 : The effect of substrate concentration on enzyme activity Objective To find out the relationship between the substrate concentration and the rate of reaction by determining the number of bubbles produce Hydrogen peroxide (H2O2) is a by-product of biochemical metabolism. An accumulation of hydrogen peroxide can be deadly‚ so it has to be decomposed. One of the decomposing factors is an enzyme called Catalase. Catalase breaks hydrogen peroxide into water and oxygen. The chemical

Properties of Different Bonds An ionic compound forms from a nonmetal and metal element. A covalent compound is formed by two non metal elements. A metallic compound is formed by two metal elements. Metallic compounds have generally high melting points‚ are loose and flexible with their electrons‚ conduct electricity well‚ and have low solubility in water. Ionic compounds are generally crystals‚ have a high melting point‚ and usually have high solubility in water and conduct electricity well when

Question 1 Electromagnetic radiation behaves both as particles (called photons) and as waves. Wavelength () and frequency () are related according to the equation where is the speed of light (). The energy ( in joules) contained in one quantum of electromagnetic radiation is described by the equation where is Planck’s constant (). Note that frequency has units of inverse seconds ()‚ which are more commonly expressed as hertz (). Part A A microwave oven operates at 2.40 . What is the wavelength

ago today I was going to watching Kurt referee his very first high school basketball game. I was so excited and so proud of him. I had no clue three years ago how much reffing would become a part of our life. Reffing is life in our household. Honestly‚ reffing takes up about 9 months of our life.

If one just pulls out a minute from the trap of economic integration and gaze around‚ it will immediately come to notice how engineering makes a difference in life. We live in a world where globalization is an important force shaping our future and we are so interested in technological advances that drive the economic engines of the world‚ but as stated by the IUPAP‚ what provides all the basic knowledge and research is simply the field of physics with all its branches of engineering. Would today’s
