Document Summary

What organelles are part of protein synthesis and processing? (ribosomes, rough er, golgi) What organelle is part of lipid synthesis? (smooth er) What organelle has acid hydrolases that catalzye hydrolysis reactions? (lysosomes) What organelle catalizes oxidation reactions and contains catalse? (peroxisomes) What process occurs inside the organelle and by what? rough er- protien synthesis through ribosomes golgi apparatus- transports materials using vesicles. Smoorth er-lipid synthesis and breack down, by enzymes. What inner structures are in the organelle? nucleus- nucleous, nuclear lamnina, nuclear evnvelope rough er- lumen, stacks. What organelles store things and what? smoot er- stores ca+ ions. Fuctions: protein manufacturing major differences betwen pro and eu: eu- membrame-bound nucleus, eu- is bigger, eu - extensive internal membrane, eu- diverse and dynamic cytoskeleton eukaryotic cells organelles: membrane-bound structures in cell, have specific shape and function. Increase chemical reaction efficiency by separating incompatible chemical reactions and grouping enzymes and substrates together.

1. The proteins of bacteria were radioactively labeled and fed to human immune cells. The proteins within the cell became increasingly more radioactive over time. This observation is the result of the activity of:

a. mitochondria. b. lysosomes. c. the Golgi apparatus. d. peroxisomes.

2. We know that different tissues in the body contain different cells. This cellular specialization is also accompanied by organelle-specific specialization causing different organelles to be abundant in cells specialized for certain roles.
