The protein nature of enzymes

• what does metabolism mean?

  all the organism’s chemical processes, comprising anabolic and catabolic pathways
• what does metabolism refer to?

  to all the reactions of the body
• what does metabolic pathway mean?

  a sequence of enzyme-controlled reactions in which a product of one reaction is a reactant in the next
• how do reactions occur?

  in sequences called metabolic pathways
• what are the reactions that occur in metabolic pathways?

  • anabolic reactions, building up molecules (e.g. protein synthesis)
  • catabolic reactions, breaking molecules down (e.g. digestion)
• whats an example of an anabolic reaction?

  protein synthesis
• whats an example of a catabolic reaction?

  digestion
• what are metabolic pathways controlled by?

  enzymes
