Module 12 Flashcards
Origin of compartmentalization and the eukaryotic cell
Backbone of all marcomolcules
carbon
What are prokaryotic cells diverse in
Metabolism
Endoplasmic Reticulum
One of the sites of protein synthesis
Golgi Apparatus
process and sorts proteins and lipids
Lysosomes
break down and recycle proteins, and other macromolecules
Mitocondira
harness energy from carbohydrates and other molecules
What is the mechanism that maintains spatial order in the cytoplasm of a prokaryote
Cell walls that support the cell from the outside
and a framework of proteins within the cytoplasm
What do eukaryotes rely on to maintain spatial order in their cytoplasam
Depend of internal scaffolding of proteins and the cytoskeleton to organize the cell
Special quality of cytoskeleton
It can be remolded quickly, enabling cells to change shape
What enables cells to function as it changes shape
Dynamic cytoskeletons and membranes
Endomembrane system
nuclear envelope, the endoplasmic reticulum, the golgi apparatus, and cell membrane
Endoplasmic recticulum
An assembly of membranes that runs through the cytoplasm
Are all membranes of the endomembrane system connected?
Yes, through membrane-bound vesicles or directly
Dynamic continunity
membranes are interchangeable where material originally added in the endoplasmic reticulum may be transferred to another part of the endomembrane system by the movement of vesicles
STABLE membranes within the eukaryotic cell
Mitochondria and chloroplast
