2 (a) What do you understand by the term multi-enzyme complex?
A multi-enzyme complex is a physical association of several different enzymes that catalyze sequential steps in a metabolic pathway. This arrangement allows for efficient channeling of substrates from one enzyme's active site to the next, preventing diffusion of intermediates and increasing the overall reaction rate.
