bar sit still on the shelf in the grocery store? Indeed‚ candy bars have a significant amount of carbohydrates (mostly simple‚ such as sugar) in their composition. The energy stored within these carbohydrates is chemical potential energy‚ and cannot actually be released or converted into usable chemical energy until it is eaten and taken up into the body‚ where various cells break down the carbohydrate molecules and contribute to the body’s metabolism via the different pathways (e.g.‚ citric acid

Living things get energy to do things through photosynthesis‚ food molecule breakdown‚ build up‚ storage‚ and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything. Photosynthesis is one way plants(plants are the main source of energy for all things)get energy to do things. The reactants of this are water‚ carbon dioxide‚ and although light energy is not a reactant‚ it is necessary once the energy from the seed is gone. Carbon

others will separate. Introduction Food is a vital source of energy that is needed for survival‚ without this energy source our bodies wouldn’t be able to function. All food can be broken down into various food groups such as water‚ proteins‚ carbohydrates‚ vitamins‚ fats‚ fibre and minerals. Our bodies need all of these food groups to function with each of them playing a specific role. These food groups are present in our every day food and are taken into our body through a process of digestion

It is also known‚ as sucrose is a sweet crystalline substance obtained from various plants‚ especially sugar cane and sugar beef. It is used a sweetener in foods to make them taste better‚ and is made up off glucose and fructose. Glucose‚ called a simple sugar‚ is a carbohydrate‚ which makes it a pure energy molecule.

Refined sugar is unhealthy when consumed in large amounts and there are healthier options. Refined sugar has no nutrition. There are also many health risks when sugar is over consumed. Humans need carbohydrates to survive but there are many healthier way to get them than too many cookies or soda. Simple sugar is made of two components. They are mainly fructose and glucose(Dubost‚ June 12‚ 2013). Sugar is naturally produced in plants during photosynthesis. It is found naturally in milk‚ fruit‚
