Channel Proteins
provide open passageways through the membrane for certain hydrophilic substances such as polar and charged molecules
Ion channels
allow the passage of ions accros the membrane
Porins
proteins that allow the passage of certain ions and small polar molecules through the membranes
Carrier proteins
bind to specific molecules, which are then transferred across the membrane after the carrier undergoes a change of shape
Transport Proteins
use energy (ATP) to transport materials across the membrane.
Recognition Proteins
give each cell type a unique identification
Adhesion proteins
attach to neighboring cells
Receptor proteins
provide binding sites for hormones or other trigger molecules
Nucleus
bounded by nuclear envelope, contains DNA
Ribosome
consist of RNA molecules and proteins
Endoplasmic Recticulum
consist of stacks of flattened sacs involved in the production of various materials
Golgi appartus
modify and packages proteins and lipids
Lyosomes
break down food (digest)
Mitochondria
aerobic respiration, ATP
Chloroplast
