Metabolism

• The anabolism and catabolism of an organism makes up it's metabolism
• Metabolic pathways are the series of chemical reactions that occur within cells to produce energy or other useful substances
• Catabolic pathway is where larger molecules are broken down into smaller ones, releasing energy.
• Anabolic pathway is where small molecules are combined together to form large complex molecules such as proteins, nucleic acids etc.
• Metabolism comes from a greek word metabole meaning change
• Metabolism is also known as Intermediary metabolism
• Metabolism helps to produce, store and utilize energy
• The main function of metabolism is to convert food into ATP (energy)
• ATP stands for adenosine triphosphate
• Metabolic reactions are catalysed by enzymes and are highly specific and regulated
• There are two aspects of metabolism
• Two aspects of metabolism are Anabolism and catabolism
• Pathways that play both anabolic and catabolic roles are Amphibolic
• Tissues or organs located in metabolism are blood, liver kidney muscle brain adipose tissue and adrenals
• There are 3 major metabolic conditions
• The major metabolic conditions are Fed state, starved state and diseased state
• In fed state there is increased energy storage
• In starved state there is increased energy release
• In diseased state there is metabolic struggle for survival
