Biological Macromoelcules 2.4 Flashcards
The monomers that make up proteins are called which of the following?
Nucleic acids
Amino acids
Fatty acids
Sugars
Amino acids
Lipids are not typical polymers because __________
Which of the following completes the sentence above?
A they are not made up of fatty acids.
B they are hydrophobic.
C they are not made of repeating monomers bonded together by dehydration reactions.
D they are a diverse set of molecules made up mostly of carbon-carbon bonds.
C they are not made of repeating monomers bonded together by dehydration reactions.
Noncovalent bonds are which of the following?
A Weak bonds, such as hydrogen bonds
B Strong bonds that require energy to form
C Formed by dehydration reactions*
D Formed by hydrolysis
A Weak bonds, such as hydrogen bonds
Hemoglobin carries 02 to cells in the body, while antibodies are an important part of our immune system. However, hemoglobin and antibodies are both proteins. Which of the following explains how two proteins can do such different things?
The function of each protein is determined by its three-dimensional structure. Hemoglobin and antibodies have very different structures.
The covalent bonds of hemoglobin are formed by dehydration reactions, while the covalent bonds of antibodies aré formed by hydrolysis.
As an enzyme, hemoglobin is able to carry oxygen and release it to cells. Antibodies are not enzymes.
Antibodies are hydrophobic molecules that interact with cell membranes. Hemoglobin is inside red blood cells, so it can carry Oz. If hemoglobin were outside the cell, it would not be able to carry 02.
The function of each protein is determined by its three-dimensional structure. Hemoglobin and antibodies have very different structures.

AGlucose
B Cellulose
C ATP
D Starch

C Nucleic acids and sugars
D Amino acids and glycogens
B Fatty acids and glycerol
The functional properties of DNA are due to which of the following?
A The fatty acids that make up the DNA molecule
B The ribonucleotides that make up the DNA molecule
C The hydrophobic properties of the DNA molecule
D The structure of the DNA molecule
D The structure of the DNA molecule

C Covalent
D Hydrolysis
Hydrolysis
