Because of this‚ the birds have very specialized

Enzymes: Food & Nutrition What are enzymes Enzymes are a type of protein produced by a living organism used to catalyze chemical reactions in cells.

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
