Mitochondria, Chloroplasts, & Peroxisomes | Chapter 4.5

MITOCHONDRIA 

  • The site of cellular respiration, a metabolic process that uses oxygen to create ATP


CHLOROPLASTS

  • Found in algae, is the site of photosynthesis


PEROXISOMES 

  • Oxidative organelles 


SIMILARITIES OF MITOCHONDRIA AND CHLOROPLASTS

  • Enveloped by a double membrane

  • Contains free ribosomes  and circular DNA molecules 

  • Grows and reproduces somewhat independently in the cell


MITOCHONDRIA STRUCTURE

  • Nearly in all eukaryotic cells

  • Smooth outer membrane, inner membrane is called Cristae

  • Intermembrane contains 2 compartments: Intermembrane space, Mitochondrial Matrix

  • Cristae present a large surface area for enzymes that synthesize ATP


CHLOROPLASTS STRUCTURE

  • Contain green pigment called chlorophyll

  • Found in leaves and other green organs of plants in algae

  • Chloroplasts contain: Thylakoids, stacks are called Granum, and Stroma internal fluid

  • Chromosomes are a group of organelles called plastid


PEROXISOMES STRUCTURE

  • Specialized metabolic compartment bounded by a single membrane

Produce hydrogen peroxide and convert it to water
