How can I effectively memorize complex biological pathways for my upcoming midterm without just relying on passive re-reading?

I am a sophomore pre-med student currently struggling to keep up with the dense metabolic pathways required for my Cellular Biology exam next week. I have already tried transcribing my lecture notes three times, but I keep blanking on the specific enzyme names during practice quizzes. My professor expects us to explain the entire process step-by-step rather than just identifying components. What active study strategies or mnemonic techniques would you recommend for retaining this amount of technical information under time pressure?
