When the PPT confuses you (e.g., "How does succinate dehydrogenase work on the inner membrane?"), go to the index of the physical Lehninger 7th edition. Read the 2 paragraphs surrounding that term. Because you already have the big picture from the PPT, those two paragraphs will stick immediately.

Simply owning the PPT is not enough. Here is the exact workflow to make the 7th edition PPT "better" than reading ever was.

In the fast-paced environment of medical school, undergraduate pre-med programs, and graduate exams (like the MCAT or GRE Biology), students face a critical problem. Reading a 1,300-page dense text cover-to-cover is often impossible. This is why the search term has exploded in popularity.

For those more biology-oriented, sources like Alberts' Molecular Biology of the Cell are often described as less dense and easier to understand, though Lehninger is preferred for in-depth "biochem" topics like enzyme kinetics.
