A sugar, a phosphate group, and a nitrogenous base make this macromolecule
What is a nucleic acid? accept DNA or RNA
100
This is what happens when two atoms form a chemical bond...two ways.
What is sharing or transfering of electrons?
100
This process occurs during polymerization (joining of monomers to make polymers) and water is removed.
What is dehydration?
100
A compound that produces hydrogen ions in solution
What is an acid?
100
One of the two major types of cells, the ones which have the ability to assemble into multi-cellular organisms and do contain nuclei.
What are eukaryotic cells?
200
These are linked together during polymerization to form complex polymers/macromolecules.
What is a monomer?
200
The main inorganic solvent in cells and is proudly known as the universal solvent
What is water?
200
Measure of how hard it is to break the surface of water created by cohesion
What is surface tension?
200
Measure of the relative acidity of solutions (range 0-14)
What is pH scale?
200
This would cause an increase in the rates of chemical reactions in cells if the enzymes were inactive.
What would be to increase the temperature of the inactive enzymes?
300
These two macromolecules have the ability to store energy in living things.
What are carbohydrates and lipids?
300
This is a catalyst and works slowly or is inactive at cold temperatures and undergoes denaturing at hot temperatures.
What is an enzyme?
300
Property of water allowing for capillary action in plants
What is adhesion?
300
This is used to weaken the acidity or alkalinity of a substance. Ex. limestone used on acidic lakes
What is a buffer?
300
Bacteria are this type of organisms
What is prokaryotic?
400
This macromolecule is made of long chains or polymers of amino acids.
What is a protein?
400
Two or more different atoms are combined in definite proportions in this chemical product
What is a compound?
400
The tendency of oxygen to be negative and the hydrogen atoms to be positive is referred to as this property of water
What is polarity?
400
A compound that produces OH- (hydroxide ions) in solution
What is a base (alkaline)?
400
Subatomic parts of an atom
What are protons, neutrons, and electrons?
500
This macromolecule actually provides the greatest amount of energy per gram of mass when metabolized.
What is a lipid?
500
This biological enzyme lowers the activation energy needed to accelerate a chemical reaction
What is a catalyst?
500
The attraction between water molecules which create the surface tension of water which allow extremely light organisms to walk across water is a result
What is cohesion?
500
The separation of hydrogen ions and hydroxide ions in water
