This element is found in all living things and is essential for building biological polymers.
What is carbon?
100
One molecule of water contains ___ hydrogen and ___ oxygen atoms.
What 2 and 1? (the order counts!)
100
This category of metabolic reaction requires water.
What is hydrolysis?
100
This is the monomer of carbohydrates.
What is a monosaccharide?
100
This molecule has a ring structure and the chemical formula C6H12O6.
What is glucose?
200
These four elements are the most common in living organisms.
What are carbon, hydrogen, oxygen, and nitrogen?
200
This property of water refers to the positive charge on the hydrogens and the negative charge on the oxygen.
What is polarity?
200
This type of metabolic reaction joins monomers together into polymers.
What is condensation?
200
This monomer of lipids looks like a long chain of carbons and hydrogens.
What is a fatty acid?
200
If you do not eat for three days, your body will rely on this long term storage polymer.
What are lipids?
300
This chemical property of carbon allows it to form four bonds, making it a very versatile element.
What are valence electrons?
300
These two properties of water allow plants to draw water through their tissues.
What are cohesion and adhesion?
(And hopefully you remembered that cohesion means water bonding to another water molecule and adhesion means water bonding to another type of molecule!)
300
Three fatty acids join one glycerol to form a triglyceride, producing this many water molecules.
What is 3?
(Think about it and visualize it-- 3 condensation reactions occur to add the fatty acids to the glycerol)
300
This monomer is the only one to include nitrogen.
What is an amino acid?
(if you said protein you are on the right track, but the "answer" refers to the monomer, which is amino acids)
300
Most unsaturated fatty acids are liquid at room temperature. This type is not.
What are trans fatty acids?
400
An increase in heat, change in pH, or exposure to certain chemicals may cause this change in a protein's three dimensional shape.
What is denaturation?
400
This concept demonstrates why water's high heat of evaporation/vaporization is important to living organisms?
What is cooling / serving as a coolant? (When water evaporates/vaporizes it removes a large amount of heat, therefore cooling the organism)
400
Digestion of food is an example of this category of reaction.
What is catabolism / catabolic?
(Hydrolysis is the right idea but this term refers to one specific reaction at a time whereas digestion as a whole is a series of many hydrolysis reactions, better referred to as catabolism.)
400
Steroids are a less common example from this category of biological polymer.
What are lipids?
400
Each of your cells is surrounded by a cell membrane. These monomers are needed to build new ones. (monomers!!)
What are glycerol and fatty acids?
500
Double bonds can be found in these monomers.
What are fatty acids and amino acids?
(The question says monomers! Read carefully if you thought lipids and proteins was the answer.)
500
This property of water explains why it is a good transport medium and is able to carry dissolved polar substances through living organisms.
What is solvent?
500
2 part question-- read carefully. This type of reaction is required to release stored energy from glycogen in your liver and muscles, which is this type of biological polymer.
What is hydrolysis and carbohydrate?
500
This polysaccharide found in plant cell walls cannot be digested by humans.
What is cellulose?
500
Amylase, which speeds up the process of breaking down starch, is an example of this category of important proteins.
