Question

cells make proteins to carry out many different processes in the body. some proteins are enzymes. an enzyme is a catalyst, or a substance that speeds up chemical reactions. some proteins are hormones. hormones regulate growth, metabolism, development, and reproduction in organisms. other proteins help transport molecules, contract muscles, defend the body against pathogens, and provide structural support for tissues. the table below shows the function of several different proteins. hemoglobin carries oxygen from the lungs to other cells in the body salivary amylase helps break down amylose, a type of starch, into glucose insulin regulates blood glucose levels collagen provides structural support for skin, blood vessels, and muscles complete the sentence. insulin hemoglobin collagen salivary amylase the protein is a hormone, and is an enzyme. the protein transports molecules, and provides structural support.

Explanation:

Insulin is a hormone that regulates blood - glucose levels. Salivary amylase is an enzyme that breaks down starch. Hemoglobin transports oxygen molecules. Collagen provides structural support for skin, blood vessels, and muscles.

Answer:

The protein insulin is a hormone, and salivary amylase is an enzyme. The protein hemoglobin transports molecules, and collagen provides structural support.
