Biochemistry — 6-topic bundle

Life at its most fundamental level is chemistry. Biochemistry bridges biology and chemistry, revealing how the molecules within living organisms interact to sustain life. We're going to focus on the "big four" macromolecules that are essential for all known life forms.

Here are the main pathways involved:

1. Energy Investment Phase: Uses 2 ATP molecules to phosphorylate glucose, making it less stable and easier to cleave.
2. Energy Payoff Phase: Produces 4 ATP molecules (net gain of 2 ATP) and 2 NADH molecules as pyruvate is formed.
