Which metal does the work?
Tap a card, then tap its group.
Ask what the site does: carrying O₂ or electrons needs a metal that changes charge, while activating water needs a strong Lewis acid that stays put.
Assumptions
•
Each card names one protein or cofactor with a single kind of metal at its working site.
•
Metals that change oxidation state (Fe, Cu, Co) carry O₂ or electrons; metals with one stable ion (Zn²⁺, Mg²⁺) hold, bend or activate molecules.
•
Proteins with two kinds of metal, such as cytochrome c oxidase (Fe and Cu), are left out.
