You’ve heard the word protein before. On a food label, in a biology class, from someone at the gym who will not stop talking about their macros. But strip away all of that and here’s what protein actually is: the molecule your body uses to do almost everything. Every reaction happening in your cells right now, every signal your body is sending, every structure holding your organs in place; there’s a protein behind it. You are, in a very literal…

The same outcome, repeated across every human who…
If you’ve spent any time on the internet, you’ve seen the joke. Someone asks a biology question and the answer is always, inevitably, without a doubt “mitochondria is the powerhouse of the cell.” It’s the one biology fact everyone remembers, usually because it was drilled into them so aggressively in school and over the internet that it’s almost impossible to forget. The problem is that’s basically where the explanation stops. Powerhouse of the cell. Great. Thanks. But what does that…
