BasepH > 7Strong StrongWeak Weak
ENZYMES - Look at the pictures on your lab sheet. Describe on your answer sheet how an enzyme works like a lock and key. Include the following terms in your explanation: enzyme, substrate, active site.Enzymes only react with specific substrates because they can only fit specific substrates like a key and lock. Substrates are like keys, and they can only fit into specific key holes called active sites. Once the “key” connects with the “key hole” the reaction can occur. The enzyme can be used again as long as another “key” comes around that fits.True or False: If the statement is true circle “T,” if it is false circle “F” and correct the statement.
1. T or F: Enzymes are not reusable.2. T or F: Enzymes are catalysts that speed up chemical reactions by lowering activation energy.3. T or F: Activation energy is the energy needed to start a reaction.4. T or F: Enzymes are carbohydrates. Proteins.5. T or F: Enzymes can denature, or change shapes, in high temperatures and high or low pH solutions.
WATER - Read the paragraph about water on your lab sheet. Use the cards to fill in the blanks in the paragraph and then fill in the paragraph on your answer sheet.
Water is a very unique chemical and essential for life. The chemical formula for water is H2O. Water is a polar molecule because the atoms in the molecule share their electrons unevenly causing a slight positive charge on one side and a slight negative charge on the other. This allows water the make weak bonds called hydrogen bonds, where the oppositely charged sides attract to each other like magnets.
These bonds give water a lot of its unique properties such as cohesion (ability to stick to itself and cause surface tension), adhesion (ability to stick to other substances), high specific heat (ability to hold a lot of heat energy), and lower density when in the solid state. Water also cannot mix with nonpolar substances like oil.

CELL TRANSPORT – Fill in.There are two types of cell transport: active and passive. Passive transport does not require energy. This type
of transport goes down the concentration gradient. Types includes diffusion (the movement of particles from high concentration to low concentration), osmosis (the movement of water from areas of low solute concentration to areas of high solute concentration), and facilitated diffusion (diffusion of larger molecules through protein channels.
Active transport requires energy. This type of transport goes up the concentration gradient. Types include protein (ion) pumps (special protein pumps that move molecules against the gradient), endocytosis (process where cell surround large molecules with cell membrane and bring it into the cell), and exocytosis (process where cells excrete large particles out of the cell by fusing vesicles with the cell membrane).
Problems – Read the problems for each picture and follow the instructions.1. Use arrows to indicate the direction of diffusion.
