Microscope
Visualize cells too small to see with naked eye
Cell fractionation
Cells are taken apart separate the major organelles from one another
Prokaryotic Cells
organisms whose cells lack a nucleus and other organelles
Eukaryotic
characterized by having a membrane-bound nucleus and other organelles
Plasma membrane
Selective barrier that allows sufficient passage of oxygen, nutrients, and waste to service the cell
Organelles
Subcellular structure that has one or more jobs in a cell
Nucleus
contains DNA
Ribosomes
Use information from DNA to make proteins
Nuclear Envelope
Encloses nucleus, separating it from the cytoplasm
What is the function of ribosomes
Carry out protein synthesis in two locations:
Cytosol (free ribsomes)
Outside of Rough ER
Smooth ER
Lacks ribsomes;
Synethsizes lipids and metapolizes carbs.
Endoplasmic Reticulum
Accounts for more than half of the total membrane in many eukaryotic cells
Golgi apparatus
Consists of flattened membranous sacs
Cisternae
flattened sac-like structures that play a crucial role in protein processing
Lysosome
Membranous sac of hydrolytic enzymes; hydrolyze proteins, fats, and nucleic acids
Contractile vacuole
Pumps out excess water out of cells
Central vacuoles
Hold organic compounds and water
Vesicle
membrane-bound sacs with varied functions
Vesicle functions:
Moving material between ER and Golgi + moving cisternae of the golgi
Endocytosis
Delivering things into cell from the extracellular environment in a process known as endocytosis
Exocytosis
Excreted such as waste and hormones to the exterior of the cell
Cytosol
Free ribsomes
Cellular Process
1: mRNA synthesized
2: Ribosome translation synthesizes protein
3: Protein enters ER for mods.
4: Protein is folded to secondary protein structure
5: Protein folded for tertiary and quaternary protein
6: Protein enters into vesicle
7: Protein enters into the cis Golgi for mods
8: Protein transported in vesicle between cisternae
9: Protein leaves Golgi in vesicle
10: Vesicle contains protein fuses with plasma membrane, protein leaves cell
Cis Face
side facing the nucleus
Trans face
Faces away from nucleus
