Organelles & Organelles of Endomembrane System Flashcards
Cytosols
Fluid liquid inside
Organelles
- membrane-enclosed bodies that perform specialized functions
- have one or more specific roles to play in the cell
Cytoskeleton
- networks of proteins that provided structural support
- mobility, reproduction, transportation
Nucleus
the membraned-enclosed organelle that stores genetic material
- direct protein synthesis, growth, etc
Nuclear Evenlope
- the doubled membrane that separates the nucleus rest of the cells
- Nuclear pores allow entry & exit
- The Border
Endoplasmic Reticulum (ER)
transport, synthesize, and store material
- produce protein for the rest of the cells
Rough ER
use for protein synthesis
- contain ribosome
Smooth ER
- used for lipid synthesis, CA2+ & detoxification
- doesn’t contain ribosome
Golgi Apparatus
- Modifies and package product from ER into vescles
- – Neurons package & release neurotransmitter to neighboring cells
Vesicle
Travels to the area inside or exit exocytosis
- - store & transport
Lysosomes
breakdown & digest cellular material using enzymes
Mitochondria
specialized, bean-shaped organelles that produce energy
- require oxygen
- produced ATP from nutrients
- apoptosis is programmed cell death
Peroxisomes
contain enzymes for lipid metabolism and detoxification
-
Microvilli
membrane extension that increases cell surface for absorption
-intestinal epithelial cells absorb a large amount of nutrients
Cilia
hair-like processes that move fluid or are used in sensory reception
