BIO 112 Chapter 5

Found in ALL cells and is made up of a phospholipid bilayer. Protects interior of cell from outside environment.

Prevents any kind of movement from one cell to the next.

The E.R. Organelle can add carbohydrates, phosphates etc... to proteins.

Made up of specialized lipids called phospholipids. These phospholipids have a hydrophilic head(phosphate group) and 2 hydrophobic tails.

A membrane bounded organelle whose main function is to digest, break down and recycle molecules/cell material. Uses hydrolytic acid enzymes and is found in white blood cells.

Anchor Junctions, cells are attatched to a basal lamina (basement membrane).

Part of the Golgi Apparatus that ships off proteins.

The entire groups of membranes and organelles in eukaryotic cells that do various tasks inside of the cell.

Communicating junction, channels between adjaecent cells. Found in heart.

Name 7 organelles/membranes in the endomembrane system.

Used for organelle and chromosome movement, cell motility (cillia/flagella). Thick

Network of fibers extending through the cytoplasma

Microtubules, microfilaments, intermediate filaments.

Tight Junction, Desmosomes, Gap Junctions.

Animal cell, function is to act as attachment, support and communication of cell.

Changes cell shape, assists muscle contraction, changes cell shape. Thin

Part of the Golgi Apparatus that recieves proteins

Main function is modification, sorting, shipping and warehousing of proteins. Has 2 sides where they recieve and ship off proteins.

Membrane enclosed organelles that contain enzymes that produce hydrogen peroxide (H2O2). Transfers Hydrogen (H) from substances in the cells to oxygen. Participates in metabolic reactions.

Membrane barrier that separates the nucleus from the cytoplasm in eukaryotic cell.

Are found bounded in the rough ER. They synthesize any proteins that function with the rough ER.

Permeability of a molecule depends

List the macromolecules present in the plasma membrane. (3)

What is the most abundant macromolecule in the plasma membrane?

What kind of molecules are most permeable ?

Ribosomes that synthesize protein all over the cell or proteins that are encoded by the nuclear genome.

Eukaryotic cell, has a cell wall, one vacuole, has plasmodesmata. Synthesizes proteins

Eukaryotic cell, has a nucleus, many vacuoles, cannot synthesize proteins.

ATP generator found mostly in muscle cells.

Abundant in protein secreting cells, located in pancreas, liver and anterior pituatary. Synthesizes phospholipids for own membrane.

Organelles that have their own DNA

Synthesizes proteins

Part of the cell membrane that is found in all cells. Medium for chemical reactions and helps cells expand grow and replicate.

Fluid that is found inside all cells and surrounds all organelles within a cell.

Also called cell membrane, selectively permeable and made up of 2 phospholipid bilayers.

No cell membrane, unicellular and lacks a nucleus- Instead has a nucleolus. Lacks membrane-bound organelles. Encased by a cell wall. DNA is found in the cytoplasm.

Multicellular with a DNA-filled nucleus. Larger and has membrane-bound organelles. Has mitochondria.

Releases glucose by breaking down glycogen in the liver. Detoxifies the body from harmful substances by adding OH groups which makes them more soluble. Storage/Creation for lipids and proteins.

Has ribosomes bounded to its membrane. Membrane bounded ribosomes get packaged in membrane vesicle as protein and shipped out of this organelle.

Connected to the nuclear envelope. Function is to create proteins for the cell. Can also act as calcium storage and lipids metabolizer.

Gated plant cell walls that allow the flow/trafficking of molecules between plant cells.
