Vacuole?
stores and releases fluid, stores waste until they can be broken down.
(in plants they help maintain shape and turgor pressure...storage of water)
What does Flagella do?
what is active transport?
requires a net input of metabolic energy
Prokaryote vs. Eukaryote?
Prokaryotes are bacteria & Archaea
Eukaryotes are plants animals and fungi
What does a Mitochondrion have?
DOUBLE membrane!!
EXTRA points if you said why!!: (for compartmentalization for different chemical reactions)
Peripheral Protein?
attached to inside or outside of the membrane ....Used for Cell signaling
What increases Surface Area in a organelle?
High number of folds in Mitochondria
Multiple Thylakoids in Chloroplasts
What are the 3 processes of Passive Transport?
1. Simple diffusion
2. Facilitated diffusion
3. Osmosis
Cell Membrane vs. Cell Wall?
Cell Membrane is a phospholipid bilayer that surrounds the entire cell...... A Cell wall is a rigid structure made of complex carbohydrates.
Vesicles?
Pieces of a phospholipid bilayer that encircle and transport large "cargo"
Receptor Protein?
Transmembrane or Peripheral protein that does not have a channel going through the middle....Used for cell signaling, ligands bind to receptor!
What is the polar part of the phospholipid?
Head Group
What causes cells to take in molecules into the intracellular space?
Endocytosis
A Nucleus is surrounded by a double membrane that protects DNA.
A Nucleolus is the site where ribosome synthesis takes place in the cell.
Cytoskeleton?
What do Membranes let through with no channel?
Small non polar molecules
What maintains water balance
Osmoregulation
Smooth Vs. Rough ER?
Smooth ER is responsible for the synthesis of lipids as well as detoxification.
Rough ER is highly folded organelle responsible for packaging proteins and sends to Golgi apparatus.
What helps fold and modify proteins?
Golgi Apparatus
Peroxisome?
Responsible for lipid hydrolysis, and uses a catalase to break down hydrogen peroxide.
What are the molecules doing if net movement is zero?
They are still moving and remain in dynamic equilibrium.
What means "the same amount of stuff"
Isotonic
Unsaturated Vs. Saturated Fatty Acid
Saturated is straight and is solid at room temperature allows for tight compaction.
