1.3 The Cell Part 3 Flashcards
What is ATP?
high energy molecules that provides energy for the cell
How is ATP created?
aerobic cellular respiration
Which organelle has two membranes?
mitochondria
Which membrane of the mitochondria contains many folds to increase surface area?
inner membrane
What is the cytoskeleton?
network of protein fibers that provide structural support and movement within the cell
What are the two types of protein fibers that make up the cytoskeleton?
microtubules
microfilaments
What are microtubules?
hollow cylinders that are involved in the movement of chromosomes during cell division and the structure of cilia/flagella
What is the flagellum?
long, whip like structures that propels or pulls a single cells organism
Where are ciliated cells found in humans?
respiratory passageways
What are the MTOCs?
microtubules organizing centers
What are MTOCs?
anchoring regions for microtubules
Where are the centrioles located?
inside of the MTOCs
What are centrioles composed of?
nine sets of three attached tubules arranged into a hollow cylinder
What anchors cilia and flagella?
basal bodies
What are microfilaments?
flexible, solid fibers made up of two intertwined polymer chains of actin molecules
