Metabolism refers to all the chemical reactions in the body of a cell or organism to keep it alive. Metabolism converts the nutrients from the food we eat in to vital energy which the body needs to carry out daily activities. The respiratory system‚ cardiovascular system and the digestive system are the three body systems that are involved with energy metabolism. There are two kinds of activities involved with metabolism processes‚ these are; building up of body tissues and energy stores and the

Copper sulphate experiment Introduction There are a number of different methods of making salts‚ such as the reaction of a metal with an acid. Copper metal‚ however‚ does not react with sulphuric acid and so another method must be used. In this experiment a basic copper compound (copper(II) oxide) will be reacted with sulphuric acid giving copper(II) sulphate as one of the products. Method 1. Wear goggles and keep your face away from the beaker during the reaction 2. Place 20 cmm3 sulphuric

Sheep” we measured the temperature of the 10 milliliters of Solution 2. Then we dropped a ball of steel wool into the test tube and measured the temperature again. We stored the test tubes on the test tube rack to observe the next day. A chemical reaction did occur in the lab. There were a color change and an odor change that was observed on Day 2 of the lab. On Day 1‚ the liquid was clear and the smell was very strong. On Day 2 of the lab‚ most of the liquid was gone but the color was a muddy

Metabolisms are all the chemical reactions that the living cells and organisms use to maintain life. It also divides into two categories: Catabolism – that breakdown the molecules to obtain energy and Anabolism – that creates all of the compounds that the cells need to function. Nutrition is an important part of the availability of nutrients that utilized in the reactions that either synthesize or catabolize the material that is employed by the cells to produce power. This power is a requirement

What are Enzymes? Enzymes are proteins that quicken chemical reaction in our body. They are found in our digestive system‚ in the stomach mostly. They are there to speed up the process of breaking down food into molecules that provide nutrients to the body. Enzymes are made up of amino acids. The Digestive System: Many people believe that when you eat a meal it drops into a pool of stomach acid‚ and then it is broken down as it goes into the small intestine to have nutrients taken out‚ and then
