Biochemistry Actual Exam Questions 100% Correct
Solutions
________ are lipids that store energy and are typically composed of multiple building
blocks containing three fatty acids attached to a glycerol molecule.
Fats
Which type of molecule makes up the double layer of a cell membrane?
Lipid
A ___________ chain is a sequence of amino acids that is the foundation for the basic
structure of a protein.
Polypeptide
One of the monosaccharides is a building block of a plant's cell wall. It is ________.
Glucose
In humans, excess blood glucose is stored in the liver and in muscle tissue in the form
of glycogen. Glycogen is a long chain of glucose molecules bonded together. Because
of this, glycogen is called a _____________________.
Polysaccharide
___________ are a large and varied groups of molecules that are usually not soluble in
water.
Lipids
Reusable, complex proteins that promote chemical reactions within cells are called?
Enzymes
, A macromolecule made up of mainly carbon and hydrogen atoms that is primarily
used for energy storage and in cell membranes.
Lipids
This is the foundation for DNA replication, the rule that states the purine adenine (A)
always pairs with the pyrimidine thymine (T) and the pyrimidine cytosine (C) always
pairs with the purine guanine (G).
Base Pair Rule
Energy stored in chemical bonds of molecules.
Chemical Energy
This is a compound made up of carbon, hydrogen, and oxygen atoms; it is used by cells
to store and release energy. Sugars are made by chloroplasts through photosynthesis
and consumed by mitochondria through cell respiration.
Carbohydrates
A single stranded nucleic acid that plays a role in protein synthesis.
RNA
This is a substance used to identify the presence of protein. It is a blue solution that
changes to pink-purple in the presence of proteins.
Biuret Solution
A macromolecule that contains carbon, hydrogen, oxygen, and nitrogen, which is used
by the body for growth and repair.
Protein
