Membranes in metabolism
a) Introduction to metabolic pathways – integrated and controlled pathways of enzyme-catalysed reactions within a cell.
(i) Anabolic (energy requiring) and catabolic (energy releasing) pathways — can have reversible and irreversible steps and alternative routes.
(ii) Membranes form surfaces and compartments for metabolic pathways to allow high concentrations and reaction rates. Protein pores, pumps and enzymes embedded in phospholipid membranes.
