Biology 4U Exam Review Intro to Biochemistry Types of bonding: Ionic Results from the attraction between two oppositely charged atoms or molecules. They must lose or gain electrons to become charged. For example‚ a sodium molecule and a chlorine molecule form an ionic bond to create sodium chloride (NaCl) Covalent Results from the sharing of one or more pairs of valence electrons to create a stable molecule. For example‚ the covalent bonding of hydrogen ions creates hydrogen gas (H2)

Enzymes: Food & Nutrition What are enzymes Enzymes are a type of protein produced by a living organism used to catalyze chemical reactions in cells. These reactions allow the cell to build things or take things apart as needed in order to grow and reproduce. How do enzymes work - in steps 1) Substrate floats near enzyme 2) Substrate and enzyme connect – which breaks it into products 3) Products are released ex) BreadFast & Co.’s use of enzymes The company uses many different

Diffusion: the movement of fluids from an area of high concentration to a lower concentration Cell theory: -All living things are made up of one or more cells and their product -Cells is the simplest unit that can carry out all processes -All cells come from preexisting cells Prokaryote: no nucleus or other membrane: bound organelles (E-Coli) Eukaryote: has a nucleus and other organelles‚ each surrounded by a thin membrane (Animals/human if multicell‚ amoeba if single cell) Organelles
