Metabolism

Question	Answer
What is metabolism?	Metabolism encompasses the integrated and controlled pathways of enzyme-catalysed reactions within a cell.
What are the two metabolic pathways?	• Anabolic Pathway • Catabolic Pathway
Describe a anabolic pathway	• Require energy • Involved in bio-synthetic processes making complex molecules from simpler ones. • Example: protein synthesis
Describe a catabolic pathway	• Releases energy • Involved in the breakdown of complex molecules into simpler ones. • Example: aerobic respiration
Give an example an anabolic reaction	• Glucose-1-phosphate ---> Starch • Enzyme: phosphorylase (potato)
Give an example of a catabolic reaction	• Starch ---> Maltose • Enzyme: Amylase
What is a synthetic pathway?	Known as a Anabolic Pathway
Which is irreversible?
Which is reversible?
Give an example of a metabolic pathway	• Glycolysis • Converts glucose to an intermediate metabolite called pyruvate
What is the alternative route?	• Sorbitol - which bypasses steps controlled my enzyme A,B and C.
