Metabolic Processes
Metabolism is a collection of chemical processes that takes place in the body to convert food into energy (kidshealth.org, N.D.). These processes are included in both digestion and respiration. The breakdown of nutrients after digestion and energy formation using the products of this are the most vital components of metabolism. Bioenergetics is the term used to describe the pathways – both biochemical and metabolic – by which the cell obtains energy (news-medical.net, 2013).
The word ‘metabolism’ derives from the Greek noun ‘metabole’, which means ‘change’ (medicalnewstoday.com, 2013). Currently, this change in terms of metabolism is divided into two categories: anabolism and catabolism.
In order for metabolic pathways to work the body must break down nutrients through digestion. Some of the products of digestion then go on to be involved in respiration. The ultimate product of this is energy, which can be used for a number of things, including DNA
