MACROMOLECULES JIGSAW- DIGESTION INTRODUCTION
 Macromolecules are large, complex organic molecules mostly made up of C and
H, sometimes N, S and P. They are the raw materials that
our body needs to provide energy and perform all cellular functions.
 These macromolecules are also known as _______________ because they are
made of many
_______________ (or building ______________) strung together.
 Analogy: _____________are to ______________ as ______________ are to
________________
 Task: In group of 4, gather information about structures, functions and
examples of the class of
macromolecule you're assigned. Once done, teach what you got to your group
members

ENZYMES:
 are ________________ that _______________ biochemical reactions such as
hydrolysis.
 Hydrolysis is a chemical reaction in which ____________breaks
macromolecules into their _________________.
 Proteins, carbohydrates, and lipids all need to be broken down by
___________________________ before the body can use them
 Enzyme names tend to be named after the substances they break down or form
and end in ____________
Type of Enzyme

Example of Enzyme and Where it Functions
Amylase: produce in the salivary glands and functions
in the mouth
Pancreatic lipase: produced in the pancreas and
functions in the small intestine
Pepsin produced by stomach glands functions in the
stomach
Pancreatic nuclease: produced in the pancreasand
functions in the small intestine
