100
Type of transport that does not require energy
What is passive transport?
100
Monomers of proteins
What are amino acids?
200
The process of removing water to link monomers and form polymers
What is polymerization?
200
The amount of energy required to get a reaction started
What is the activation energy?
200
These molecules form channels and pumps in order to help transport substances across the cell membrane
What are proteins?
200
Small molecules like oxygen undergo this process when they move from an area of high concentration to low concentration
What is diffusion?
200
The type of bonds that form between water molecules due to attraction between the negative end of one water molecule and the positive end of another water molecule
What are hydrogen bonds?
300
The monomers of carbohydrates
What are monosaccharides or sugars?
300
Any substance that speeds up the rate of a chemical reaction without being consumed in the process
What is a catalyst?
300
Means "water loving" and describes the heads of phospholipids, which always face outwards in the cell membrane
What is hydrophilic?
300
Involves the movement of molecules through a protein channel from an area of high concentration to an area of low concentration
What is facilitated diffusion?
300
Type of solution that has a low solute concentration
What is a hypotonic solution?
400
The process of adding water in order to break down large macromolecules?
What is hydrolysis?
400
Proteins that are made by cells and speed up the rate of a chemical reaction without being consumed in the process
What is an enzyme?
400
Property of the cell membrane that describes how some substances can easily pass across while others cannot
What is selectively permeable?
400
Type of transport that involves energy and moves substances from an area of low concentration to an area of high concentration
What is active transport?
400
A human blood cell placed in this type of solution will neither gain nor lose mass; water will move in equal amounts in both directions across the membrane
What is an isotonic solution?
500
Type of fatty acid that has at least one double bond between carbon atoms and is typically liquid at room temperature
What is unsaturated?
500
The reactants of an enzyme-catalyzed reaction
What are substrates?
500
Present in animal cell membranes and is scattered among the phospholipid tails. Makes the membrane less fluid.
What is cholesterol?
500
A human blood cell placed in this type of solution will shrink
What is a hypertonic solution?
500
These are the parts of a triglyceride molecule
What is a glycerol molecule and 3 fatty acid chains?
