AND ANSWERS
Proteins - Answer-what are the most important biochemical compound?
Carbon, Hydrogen, Oxygen, Nitrogen - Answer-what 4 elements are proteins composed
of?
Proteins - Answer-these occur in all living things and are the fundamental building
blocks of living matter.
Proteins - Answer-these constitute a large part of the solid matter of animals, for
example, nervous tissue, muscles, cartilage, tendons, ligaments, and blood.
Plants - Answer-what are the primary proteins producers in nature?
Proteins - Answer-plants form carbohydrates and then combine simple carbohydrate
units with ammonia or other nitrogen compounds found in soil to produce various types
of _______.
Amino Acids - Answer-proteins are very large complex molecules which contain many
________ molecules that are chemically combined.
Peptide - Answer-proteins are chains made up of amino acids held together with
_______ bonds.
Polymers - Answer-proteins are ______ of amino acids because they are made up of
amino acids.
Amino Acids - Answer-these join together to make thousands of different protein chains.
These chains then fold to create 3D structures.
Essential - Answer-the amino acids that the body cannot produce are called ________
amino acids.
9 - Answer-how many essential amino acids are there?
22 - Answer-how many of the amino acids in protein are important to human health?
Protein Synthesis - Answer-to make the proteins the body needs to maintain muscles,
bones, blood, and body organs.
, NH2, COOH - Answer-an amino acid is the structural unit or building block of a protein
which contains one ______ and one ________.
Amino Acid - Answer-
Glycine - Answer-what is the simplest amino acid?
Glycine - Answer-
Glycine - Answer-the smallest identifiable protein molecule is a single amino acid
molecule called ______.
Glycine - Answer-this amino acid consists of methyl amine chemically joined to a
carboxylic acid molecule.
Amphoteric - Answer-this is a compound that can act as both an acid and a base in
solution.
True - Answer-an amino acid is amphoteric because of its structure. T/F
Buffers - Answer-what does an amino acid act like in a solution?
Buffers - Answer-a substance that when placed in solution are capable of neutralizing,
within limits, both acids and bases.
Neutralizing - Answer-what helps solutions maintain their original or constant pH?
Buffers - Answer-what protects a solution against changes in pH?
Buffers - Answer-since proteins are polymers of amino acids, they are also _______.
Peptide - Answer-this bond occurs between the carboxyl atom of one amino acid and
the amine nitrogen of another.
Peptide Linkage - Answer-this occurs between the amine group of one amino acid and
the carboxyl group of another. Water is formed for each linkage that takes place.
Water, Peptide Bond - Answer-one ______ is formed by peptide linkage, it breaks away
and leaves a spot for the _________ to form and join the two amino acids together.
Carbon, Nitrogen - Answer-a peptide bond is a ________-_______ bond
Dehydration - Answer-the peptide bonds in a polypeptide chain are formed in a
_________ reaction since one molecule of water is removed for each peptide bond that
forms.
