Proteins Flashcards
What do proteins do in the body?
Proteins perform different jobs like breaking down food, carrying substances, and protecting against diseases.
Give an example of a digestive enzyme.
Amylase helps break down food into smaller pieces for absorption.
What is the function of transport proteins?
They carry substances like oxygen throughout the body.
Name a protein involved in providing structure to cells.
Actin helps build structures like the cytoskeleton.
What do hormone-signaling proteins do?
They coordinate different body functions.
What is the role of defense proteins?
They protect the body from foreign pathogens.
Which protein enables muscle movement?
Myosin is involved in muscle contraction.
What do storage proteins do?
They store nutrients for the early development of embryos.
What are proteins made of?
Proteins are made up of smaller units called amino acids.
What is the bond that joins amino acids together called?
It’s called a peptide bond.
What are the four levels of protein structure?
The levels are primary, secondary, tertiary, and quaternary.
What is the primary structure of a protein?
It’s the sequence of amino acids.
What forms when secondary structure proteins fold into shapes like helices or sheets?
They form alpha helices or beta pleated sheets
What determines the overall 3D shape of a protein?
The tertiary structure.
When multiple protein subunits interact, what structure is formed?
It’s called the quaternary structure.
