Cell Structure and Function Biology 2121 Chapter 3

Organelles – specialized structures Cytoplasm Cytosol - collodial mixture Inclusions Important Organelles Mitochondria – ATP synthesis Ribosomes – protein synthesis Peroxisomes Catalase and oxidase enzymes – detoxification Centrioles – animal cell mitosis Cytoskeleton – support

Endomembrane System Nucleus DNA-Chromosomes and genes Rough Endoplasmic Reticulum Ribosomes and modification of proteins Golgi Apparatus Modification of proteins – export or import Lysosomes

Fluid Mosaic Model – Selectively Permeable Phospholipid Bilayer Polar Heads – face water Hydrophilic Nonpolar Fatty acid tails Hydrophobic Proteins Transmembrane – Integral Peripheral Cholesterol

Tight Junctions Epithelial cells – skin and digestive tract Impermeable junctions Gap Junctions- “nexus” Communication Transmembrane proteins – connexions Heart and smooth muscle

The Role of Proteins Transport Intercellular Joining Cell to Cell Recognition Glycoproteins Attachment site for Extracellular Matrix and Cytoskeleton
