Enzymes lower the amount of energy needed in a chemical reaction. This happens because enzymes are catalysts‚ so they speed up the activation rates that occur in living organisms. Without enzymes‚ it would be difficult to break down particles like food in the digestion system. Enzymes are all very specific to what chemical reactions they will work with‚ and the temperature‚ pH‚ and salt concentration have to be a specific levels in order for the enzyme to function. The structure of each enzyme has

Does caffeine affect heart rate? Background Information: Caffeine is a bitter white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. A German chemist‚ Friedrich Ferdinand Runge‚ discovered it in 1819. Plants produce caffeine as an insecticide. It is found in varying quantities in the beans‚ leaves‚ and fruit of over 60 plants‚ where it acts as a natural pesticide that paralyses and kills certain insects feeding on the plants. Cocoa in South America‚ coffee in Africa

Business Environment 1. Define the term ‘Business Environment’. Explain the various elements of the internal environment of business. What do you understand by the task environment? A business environment can be defined as the surroundings‚ external factors‚ circumstances and all the influencing factors that affect the operations of a business. In a business environment there are two main classes of factors namely internal and external. The internal factors are considered those that the company

The purpose of the experiment conducted was to observe if a higher concentration or lower concentration gradient would affect the diffusion rate of the iodine moving through the starch concentration. This was shown to be an accurate experiment as with a higher concentration gradient the diffusion that did occur happened a lot faster and diffused more efficiently compared to no iodine solution and just water. This is due to the molecular collisions speeding up the experiment in the time period given

factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory experiment was to determine which solution would have the highest impact on oxygen production within the aquatic plant‚ Elodea densa (Brazilian Waterweed). The

1. Explain how exchange rate targeting by the central bank can affect the balance of payment position of a country (Hint: Consider the current and the capital accounts) Exchange rate targeting is whereby the exchange rate becomes the nominal anchor. The subject of the most favorable monetary regime for small open developing economies is still widely discussed. The advantages and disadvantages of different exchange rate regimes are far too many to be readily captured and used to come up with a specific
