Human Anatomy Chapter 2 The Cell

Front 1

There are ___ different types of cells in the human body?

Back 1

200

Front 2

What are the 3 types of Plasma Membranes?

Back 2

Phospholipids, cholestrol, and glycolipids

Front 3

2 types of Plasma Membrane Proteins

Back 3

integral and peripheral

Front 4

Exocytosis

Back 4

REQUIRES ATP
process a cell uses to move LARGER molecules from the inside of cell to outside. Fuses with membrane to do this.

Front 5

Endocytosis

Back 5

Process where cell aquires materials from the extracellular fluid.
3 different types:
phagocytosis (cell eating)
pinocytosis (cell drinking)
receptor (mediated endocytosis)

Front 6

Endoplasmic Reticulum (organelle)

Back 6

network of flattened membrane sacs.
primary function is lipid synthesis.
2 types:
Smoother ER and Rough ER

Front 7

Golgi Apparatus (organelle)

Back 7

"FedEx" of the cell
Tags and ships molecules out of the cell

Front 8

Lysosome (orprotein synthesis)ganelle)

Back 8

Recycling center of cell

Front 9

Mitrochondri (organelle)

Back 9

Powerhouse of cell
Produces ATP
Requires Oxygen of function

Front 10

Ribosomes (organelle)

Back 10

protein synthesis
"Reads" genetic info (mRNA) from nucleus
Assemble amino acids into proteins
May be "free" in cytoplasm or attached to ER

Front 11

Cytoskelton

Back 11

Polymers of many small protein molecules.
Give cell its shape and allows cells to move (but not all cells can move)

Front 12

Centrosomes

Back 12

Organize cytoskelton for cell division.

Front 13

Cilia and Flagella

Back 13

Projections of cell that move.
Cilia causes the layer of mucus on the outside to move in one direction.

Front 14

Nucleus

Back 14

The Control Center
-contains genetic material (DNA)
-nucleue envelope is a structure that controls the entry and exit of molecules in nucleus.
-Double helix
