Tricarboxylic acid

Tricarboxylic acid, also known as the Krebs cycle or the citric acid cycle, is like a big circle party that happens in our cells.

Imagine your cells are throwing a party, and they need a lot of energy to keep the party going. The tricarboxylic acid cycle is like the main attraction that provides the energy, just like a big bounce house that keeps the party going.

To start the cycle, a molecule called acetyl-CoA enters the party. This molecule is made up of carbon, hydrogen, and oxygen. Then, it meets with a molecule called oxaloacetate, and they become best friends.

Together, they do a little dance, and that dance creates energy in the form of ATP. ATP is like a superhero that gives energy to our cells so they can do their job.

After the dance, the two molecules join together and become one, forming a new molecule called citrate. Citrate goes through a bunch of different steps, and each step creates more energy in the form of ATP.

Finally, after going through a bunch of steps, the molecule goes back to the beginning of the cycle and starts over again. It's like a never-ending dance party where everyone is having a great time and creating lots of energy.

In summary, the tricarboxylic acid cycle is like a big circle party that happens in our cells to create energy in the form of ATP. It starts with two molecules joining together, doing a dance, and creating energy. Then, the molecule goes through a bunch of steps and finally goes back to the beginning to start the cycle all over again.
