b) They are made of amino acids What is the function of a protein kinase?
Protein kinases function to phosphorylate other proteins, altering their activity. What is the building block of a protein?
The building block of a protein is an amino acid. What are the building blocks of proteins called?
The building blocks of proteins are called amino acids. At how many positions are the amino acids the same between the two species?
This question requires specific data to answer, which is not provided. What does the field of proteomics study?
Proteomics studies the structure, function, and interactions of proteins within an organism. Proteins can have many different functions! Which of the following is not a function of proteins? a) Energy storage b) Enzyme catalysis c) Transport d) Structural support
a) Energy storage Which of the following is not a function of a protein? a) Catalysis b) Transport c) Genetic information storage d) Structural support
c) Genetic information storage Proteins are building blocks for what?
Proteins are building blocks for tissues and organs in living organisms. What type of information is used to direct different polypeptides to fold into different shapes?
The sequence of amino acids in the polypeptide chain directs folding into different shapes. Which structure in a polypeptide gives rise to the unlimited diversity in protein form and function?
The primary structure, or sequence of amino acids, gives rise to diversity in protein form and function. What kind of bond holds amino acids together?
Peptide bonds hold amino acids together. What is created when amino acids join together in chains?
When amino acids join together in chains, they form polypeptides or proteins. Which statement accurately describes the production and degradation of proteins in a cell?
Proteins are synthesized by ribosomes and degraded by proteasomes. What are the building blocks of a protein?
Amino acids are the building blocks of a protein. Which is composed of amino acids and determines all the structures and functions of organisms?
Proteins are composed of amino acids and determine structures and functions of organisms. Where are proteins made in the cell? a) Nucleus b) Ribosomes c) Cytoplasm d) Cell membrane
b) Ribosomes What maintains the secondary structure of a protein?
Hydrogen bonds maintain the secondary structure of a protein. Where is the linkage made that combines two amino acids?
The linkage is made at the peptide bond between the carboxyl group of one amino acid and the amino group of another. What is the monomer building block of proteins?
The monomer building block of proteins is an amino acid. Which of the following is a function of protein? a) Energy storage b) Catalysis c) Genetic information storage d) None of the above
b) Catalysis What might happen if a protein has a change in one amino acid?
A change in one amino acid can alter the protein's structure and function, potentially leading to loss of function or disease. What are considered the building blocks of proteins?
Amino acids are considered the building blocks of proteins. Which three statements best describe proteins? a) They are made of amino acids, they catalyze reactions, they store genetic information b) They are made of amino acids, they provide structural support, they catalyze reactions c) They store energy, they are made of nucleotides, they transport oxygen
b) They are made of amino acids, they provide structural support, they catalyze reactions Which of these proteins is most likely a glycoprotein?
A protein with attached carbohydrate groups is most likely a glycoprotein. What is the proteome?
The proteome is the entire set of proteins expressed by a genome, cell, tissue, or organism at a certain time. What is the relationship between proteins and amino acids?
Proteins are polymers made up of amino acid monomers. What is the monomer that makes up proteins?
The monomer that makes up proteins is an amino acid. Which monomer units combine to form proteins?
Amino acid monomer units combine to form proteins. What is the main determinant of a protein's tertiary structure?
The interactions between the R groups of amino acids determine a protein's tertiary structure.
