3

• The endomembrane system is involved in chemical
  reactions and the movement of products through
  the cell

4

• Several organelles participate in the
  endomembrane system.
• Many processes occur in the endoplasmic
  reticulum.
• There are two types of endoplasmic reticulum.
• rough endoplasmic
  reticulum
• chemically modifies
• proteins

  endomembrane system.
• There are two types of endoplasmic reticulum.
• rough endoplasmic
  reticulum
• smooth endoplasmic
  reticulum
• produces lipids

6

• Several organelles are part of the endomembrane
  system
• Vesicles transit between ER, other organelles,
  cell membrane

8

• The Golgi apparatus processes and packages
  biomolecules for transit to other membrane bound
  organelles.
• Lysosomes contain enzymes that digest cellular
  structures biomolecules

9

• Other organelles have various functions.
• Vacuoles are fluid-filled sacs that hold
  chemicals.
• all plants, protists, fungi, some animals
