Freestyle
100
It is the basic unit of matter.
What is an atom?
100
This is an attraction between molecules of the same substance.
What is cohesion?
100
This process changes or transforms one set of chemicals into another.
What is a chemical reaction?
100
This macromolecule's main function is to provide energy to organisms.
What is carbohydrates?
100
This analogy is often used to describe the way a substrate binds to an active site on an enzyme.
What is the lock and key?
200
This is formed by the binding together of protons and neutrons.
What is the nucleus?
200
This special property of water causes water to rise from the roots of plants up through the stem and to the leaves.
What is capillary action or (adhesion)?
200
This type of energy is required to get a reaction going.
What is activation energy?
200
This kind of covalent bond is represented by a double line between to carbons. Example: C = C
What is double covalent bond?
200
Humans release energy needed for growth and other biological functions through this process, which is essectially the breakdown and digestion of food.
What is metabolism
300
These are atoms of the same element, but with a different number of neutrons.
What are isotopes?
300
In water the charges of oxygen are hydrogen are these.
What is oxygen (negative) and hydrogen (positive)?
300
Enzymes are made of this type of macromolecule.
What is a protein?
300
These smaller units join together to form polymers.
What is a monomer?
300
These monomers are compounds with an amino group on one end and a carboxyl group on the other end.
What is an amino acid?
400
This is an example of a compound formed when atoms join together with covalent bonds.
What is a water molecule?
400
Water is said to be this type of molecule because it forms multiple hydrogen bonds and has unevenly distributed charges.
What is polar?
400
These proteins act as catalysts to chemical reactions in our bodies.
What are enzymes?
400
DNA and RNA are examples of this type of macromolecule.
What is a nucleic acid?
400
This is a signal to which an organism responds.
What is a stimulus?
500
These bonds are formed when an electron or electrons transfer from one atom to another.
What is an ionic bond?
500
These are types of bonds that form between 2 or more water molecules.
What are hydrogen bonds?
500
These reactants come together at the active site of an enzyme so that they can be transformed by a chemical reaction.
What is a substrate?
500
All macromolecules contain these 2 elements.
What is hydrogen and carbon?
500
Two of the three things that affect the function of an enzyme are these.
What is temperature and pH?
