Biology Cell Note sheet Part Two The Cell Membrane
How is a window screen like a cell membrane?
The cell membrane is a flexible boundary of a cell that separates a cell from its
surroundings. It allows nutrients to enter the cell and wastes to be removed.
pH and Living
Scientists use something called the pH scale to measure how acidic
or basic a liquid is. The scale goes from 0 to 14. Distilled water is
neutral and has a pH of 7. Acids are found between 0 and 7. Bases
are from 7 to 14
Toothpick-ase: Introduction to Enzymes
Enzymes are used in all metabolic reactions to control the rate
of reactions and decrease the amount of energy necessary for
the reaction to take place. Enzymes are specific for each
reaction and are reusable. Enzyme
