Basics of Proteins
They are the building blocks of proteins.
What are amino acids?
Proteins that speed up chemical reactions.
What are enzymes?
Proteins are most important in the body for this function.
What is growth and repair?
The sequence of amino acids in a polypeptide chain.
What is the primary structure?
This is the process of removing water to form peptide bonds
What is dehydration synthesis?
The four main elements found in proteins.
What are carbon, hydrogen, oxygen, and nitrogen?
This protein hormone lowers blood sugar.
What is insulin?
A food that provides all the essential amino acids.
What is a complete protein (like eggs, fish, or soy)?
The folding of amino acid chains into alpha-helices and beta-pleated sheets.
What is the secondary structure?
The specific three-dimensional region of an enzyme where substrate molecules bind and undergo a chemical reaction to form products.
What is the active site?
The bond that links amino acids together.
What is a peptide bond?
The main role of hemoglobin.
What is transporting oxygen?
The main site where protein digestion begins.
What is the stomach?
The overall three-dimensional shape of a polypeptide.
What is the tertiary structure?
An iron-containing protein most commonly seen in the blood of vertebrates.
What is hemoglobin?
This is the simplest amino acid.
What is glycine?
Antibodies belong to this category of protein function.
What is defense?
A lack of protein in the diet can cause this general condition.
What is malnutrition?
The structure formed when two or more polypeptide chains combine.
What is the quaternary structure?
This type of protein defends the body against pathogens and is also known as an antibody.
What is a defensive protein?
Proteins are sometimes called the body’s “___ blocks.”
What are building blocks?
Actin and myosin are proteins used in this process.
What is muscle contraction?
Meat, eggs, beans, and nuts are examples of this.
What are sources of protein?
A change in temperature or pH can cause this process, which alters a protein’s structure and function.
What is denaturation?
This protein hormone helps regulate blood sugar by allowing cells to take in glucose.
What is insulin?
