SWBAT define and differentiate synthesis and digestion reactions

SWBAT define enzyme & I.D. the structure

Reactions

• In a digestion reaction, complex molecules are broken down into simpler ones.

• In a synthesis reaction, simpler molecules are combined to produce complex molecules. 

  
  

• Energy is stored in the bonds between atom

What kind of chemical reaction can break down a macromolecule?

Multiple Choice

A synthesis reaction can be represented as ________________________.

• AB + CD → AC + BD

• A + B → AB
• A + BC → B + AC

STAMP IT in your notebook

•  Synthesis reactions create bonds and store energy whereas digestion reactions break bonds and release energy. 

• Each have their own building blocks and functions, all macromolecules are made up of repeating smaller subunits.

• Synthesis reactions: combine molecules to become more complex

• Digestion reactions: breaks down molecules to become simple
