What Are Proteins

This video explores the structure and function of proteins, which are made of amino acids. It discusses the role of proteins in our diet, how they are digested, and how DNA guides protein synthesis. The video also covers an experiment to test for proteins in food and highlights the diverse roles proteins play in the body, including forming structures, acting as hormones, and facilitating active transport.

• Fish

• Beans

• Bread

• Eggs

What color indicates the presence of protein when using the biuret test?

• Blue

• Green

• Lilac or purple

How does DNA influence protein synthesis?

• It provides energy for the process

• It transports proteins across cell membranes

• It acts as a template for building proteins

• It breaks down proteins into amino acids

Which of the following is a function of proteins in the body?

• Transporting oxygen in the blood
