E1 Ch 5 Flashcards
4 functions of cell or plasma membrane
Barrier
Structural support
Cell signaling and communication
Regulate cell growth
T/F All prokaryote cell lack membrane bound nucleus
True
Highway of cytoskeleton
Microtubules
Protein be made and processed for export from the cell sequence
Er -> Golgi apparatus-> secretory vesicle > cell membrane
Nearby cells that aren’t touching can communicate by release of what signals
Paracrine
Process of taking material in bulk to a cell
Phagocytosis
Sodium potassium pump
3 sodium ions bind to cytoplasmic side of protein
3 sodium ions are transported into the cell
ATP binds to the protein which becomes phosphorylated
If you were a rlly thirsty cell which process would you use to take in so,e nutrients secreted by one of your neighbors?
Pinocytosis
Biological molecule that adds phosphate to other molecule is
Kinase
Some enzymatic receptors and most protein coupled receptors utilize other substances to relay the message within cytoplasm. Small molecules or ions called
Second messengers
How are metabolic pathways controlled
Feedback inhibition
Forms of signaling
Direct contact
Paracrine signaling
Endocrine signaling
Synaptic signaling
Basic mechanism for cellular communication
Desmosomes
Insulin is an example of what type of signaling
RTK
