List the molecules termed “organic compounds”.
lipids
carbohydrates
proteins
nucleic acids
What is the “building block” of carbohydrates?
monosaccharide
Small organic molecules used as “building blocks” are called ___.
monomers
___ is the most abundant and important inorganic compound in living material, making up 60-80% of the volume of most living cells.
Water
Homeostasis of acid-base balance is carefully regulated by the kidneys and lungs and by chemical systems (proteins and other types of molecules) called ___. This chemical system helps to resist large swings in the pH of body fluids by releasing hydrogen ions when the pH begins to rise and by binding hydrogen ions when the pH drops.
buffers
Name the molecules unique to living systems that all contain Carbon (aka name the 4 organic compounds).
carbohydrates, lipids, proteins, nucleic acids
?
(T/F) The building blocks of lipids are monosaccharides.
false
(T/F) Lipids are insoluble in water but dissolve readily in other lipids and in organic solvents such as alcohol or ether.
true
(T/F) Lipids include triglycerides, phospholipids, and glucose.
false
(T/F) Proteins are the body’s basic structural material and have many vital functions.
true
(T/F) Nucleic acids are composed of carbon, oxygen, hydrogen, nitrogen, and phosphorus, and are the largest molecules in the human body. The structural units of nucleic acids are nucleotides.
true
(T/F) Both DNA and RNA are types of organic compounds known as carbohydrates.
false
___ compounds are made by dehydration synthesis and broken down by hydrolysis.
