Anticipation Guided

Proteins are made up of smaller units called amino acids.

All proteins have the same function in living organisms.

The sequence of amino acids determines a protein’s shape and function.

Proteins provide energy for cells just like carbohydrates and lipids.

Enzymes are proteins that speed up chemical reactions in cells.

The shape of a protein can be changed by changes in temperature or pH.

Protein structure includes four levels: primary, secondary, tertiary, and quaternary.

The primary structure of a protein is the specific order of amino acids.

The quaternary structure refers to how multiple protein subunits assemble together.
