enzymes are biomolecules made of long chains of amino acids. amylase is an enzyme found in human saliva that starts to break down starches when the food is in our mouth. which of the following best describes amylase?
it is a type of carbohydrate that speeds up chemical reactions
it is a type of amino acid that speeds up chemical reactions
it is a type of lipid that speeds up chemical reactions
it is a type of protein that speeds up chemical reactions

Explanation:

1. For the first question, lipids store energy in the form of fat in the body for long - term use. Carbohydrates are for quick energy, proteins are for building and repairing tissues, and nucleic acids are for storing genetic information.
2. For the second question, enzymes are proteins made of amino - acid chains. Amylase is an enzyme (a type of protein) that speeds up the chemical reaction of starch breakdown.

Answer:

1. Lipids
2. It is a type of protein that speeds up chemical reactions
