Document Summary

They have a smooth outer membrane and an inner membrane folded into crustal. Some metabolic steps of cellular respiration are catalyzed in the mitochondrial matrix. Cristae present a large surface area for enzymes that synthesize. Chloroplasts contain chlorophyll as well as enzymes and other molecules that function in photosynthesis: found in leaves and other green organs of plants and in algae. Chloroplast structure includes: thylakoids membranous sacs stacked to form a granum, stroma the internal fluid. The chloroplast is one of a group of plant organelles called plastids. Peroxisomes are specialized metabolic compartments bounded by a single membrane: produce hydrogen peroxide and convert to water, peroxides perform reactions with many different functions. The cytoskeleton is a network of fibers extending throughout the cytoplasm. It organizes the cells structure and activities anchoring many organelles. It is composed of three types of molecular structures: microtubes, microfilaments, intermediate filaments. Microtubules - thickest of the three - tubulin.
