A galaxy is a group of stars, interstellar gas, dust, etc.
There are different types of galaxies. They are all categorized by their shape:
Spiral: a spiral galaxy has a disc in the centre and curved arms that come out of it.
Irregular: it does not have a specific shape. It is just a mass of things.
Elliptical: an elliptical galaxy looks basically like a disc in the universe.

An enzyme is a type of protein found within a cell. Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life.
The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.
Enzymes are produced naturally in the body.
For example, enzymes are required for proper digestive system function. Digestive enzymes are mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. You can also take enzymes in pill form if you’re having certain digestive problems.
