energy production. They are also the responsible location for which respiration takes place. Mitochondria contain enzymes that help convert food material into adenosine triphosphate (ATP)‚ which can be used directly by the cell as an energy source. Mitochondria tend to be concentrated near cellular structures that require large inputs of energy‚ such as the flagellum. The role of the mitochondria is very important in respiration. In the presence of oxygen‚ pyruvate or fatty acids‚ can be further

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

Investigating a factor that affects the rate of enzyme activity Enzymes speed up reactions. They have an area with a very particular shape called the ‘active site’. When the right molecule comes along (substrate molecule) it will fit perfectly into the active site and there will be a reaction. After the reaction the products then leave the active site. This process is often referred to as the lock and key theory as only one enzyme can carry out one type of reaction. The catalase enzyme speeds

Heart Rate Research Question: Do different exercises have different effect on heart rate? Method: 1. Find test subject 2. Prepare for activity (stretching) 3. Take heart rate of subject before exercise 4. Record heart rate 5. Do sit ups for 2 mins 6. Time using stop watch 7. Record heart rate 8. Allow subject to rest (lower heart rate) 9.

but before Obama came to office the unemployment rate was not bad. Obama has brought us into greater debt but has helped reduced the unemployment rate drastically. Thanks to this there is less crime in America. If we want to be a strong committed country there should be no one without a job. The unemployment rate before Obama in 2000 was 4.2 and once Obama came to officer the unemployment rate is 7.9. Obama must reduce the unemployment rate. Unemployment only makes the countries debt go up

Coursework Rates of Reaction Research The rate of reaction tells us how quickly a chemical reaction takes place. It is important for people in industry to know how fast a reaction goes. They have to know exactly how much of their product they can make each hour‚ day or week. In a shampoo factory‚ the rate might be 100 bottles per minute. We can’t work out the rate of a reaction from its chemical equation. Equations can only tells us how much product we can get. They don’t say how quickly

increase the competitiveness of domestic goods. The increase of nominal exchange rate can make the real exchange rate Increase‚ which will stimulate export and restrict import. It means that the trade balance will be improved. When the rate rises‚ the price of export is cheaper by counting in foreign currency‚ and the price of import in domestic currency increases‚ which is called the price effect. The decrease of exchange rate makes the price of export cheaper‚ the export volume increase‚ while the import
