is an remote controlled vehicle without passengers‚ or an unmanned aerial vehicle or UAV. There has been a lasting debate over whether drones should be regulated by the government or if they shouldn’t. Drones should be regulated by the government to protect our privacy‚ wildlife‚ and national security. One reason that drones should be regulated by the government is that drones can endanger wildlife. In the article‚ “Are private drones privacy pirates?” (source 3)‚ it states‚ “In April‚ volunteers

1.7 Factors that affect the activity of an enzyme It is important when working with enzymes to understand basic enzymatic theory behind them when selecting conditions to measure the activity of the enzymes. The factors that are known to affect the concentration of enzymes are temperature‚ pH‚ concentration of enzyme‚ concentration of substrate‚ buffer type and concentration‚ the presence of any inhibitors and cofactors (Worthington-biochem.com). 1.7.1. Temperature With most catalysed reactions‚

20th‚ 2012 Enzyme Lab What is an enzyme? Enzymes are specialized protein molecules simplifying most of the body’s metabolic processes such as‚ supplying energy‚ digesting foods‚ purifying your blood‚ executing the body of waste products etc. Enzymes act as catalyst by speeding up the reactions that happen in our bodies and decreasing the amount of activation energy needed to break a complex down. A reactant is any given enzymatic reaction is called a substrate for that specific enzyme. The place

Developing my own self-regulated learning plan I followed self regulated learning process in my preparation for OSS exam‚ which really helped me. First of all I clearly defined my main goal‚ to pass OSS exam. In order to achieve my goal I needed 5 months‚ before the exam will take place. As for allocation of time for every section of exam I should spend 3 weeks. I will study at home‚ library and can take private courses if I will stuck at certain topics. These mentioned steps will take at Forethought

Enzymes Enzymes are… * Biological catalysts Lower the energy level needed for a biochemical reaction to occur. This energy level is called activation energy. * Proteins Polypeptide chains made up of 100’s-1000’s of amino acids in a specific sequence. * Do not get “used up” in a reaction The number of “uses” of an enzyme depends on the enzyme. * Work more efficiently at certain optimum temperatures. * They are “reaction-specific”. Each enzyme is included in one reaction.

on Enzyme Activity Rate Abstract The reaction rate of an enzyme can be affected by many factors‚ and the purpose of this experiment was to find out how an increasing substrate concentration influences the rate of an enzyme activity; we obtained data from recording the absorbance of the samples which contain the same amount of potato juice (enzyme oxidase) and different amount of catechol (substrate) while holding pH and temperature constant. Our findings illustrate that the rate of enzyme activity

Self-Regulated Learning "Learning is what most adults will do for a living in the 21st century." (Alfred Perlman). As he said‚ there is no doubt that learning is a very important skill especially in modern society because of the knowledge explosion and rapid developing of information technology. However‚ there are different results with different learning methods. Good learning method can lead to success easier‚ on the contrary‚ poor learning method means wasting time and energy. Therefor

on the rate of enzyme activity of Catalase Aim To investigate the effect of substrate concentration (manipulated by increasing concentration of hydrogen peroxide) on the rate of enzyme activity of catalase‚ produced by liver cells‚ on the decomposition of hydrogen peroxide. Introduction Enzymes are biological catalysts that increase the rates of reactions. In an enzyme-catalyzed reaction‚ the substrate binds to the active site and forms enzyme-substrate complex with the enzyme through the lock

Biology Homework Explain how blood sugar levels are regulated in your body. Blood sugar level (also known as blood glucose level) is the amount of glucose (sugar) in the blood. The amount of glucose in the blood is expressed as millimoles per litre (mmol/l). Blood sugar levels are tightly regulated in the human body. Glucose‚ transported via the bloodstream‚ is the primary source of energy for the body’s cells. The levels of glucose in the blood are monitored by the cells in the pancreas. If the
