what type of biological molecule is an enzyme?

Almost all enzymes are proteins.

Since this is not my area of expertise, I searched Google under the key words "enzymes" to get these possible sources:

In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search. Also see http://hanlib.sou.edu/searchtools/.

I hope this helps a little more. Thanks for asking.

An enzyme is a type of protein, which is a class of biological molecules. To determine this, one needs to understand the basic composition of enzymes and proteins.

To gain this knowledge, you can follow these steps:

1. Search for "enzyme definition" in a search engine or a reliable biology textbook.
2. Review multiple sources to understand the common characteristics and functions of enzymes.
3. Look for information on the composition of enzymes and proteins.

Upon conducting this research, you will find that enzymes are specialized proteins that act as biological catalysts, facilitating or speeding up specific chemical reactions in living organisms. They are composed of long chains of amino acids folded into intricate 3D structures.
