Cell Theory & Plasma Membrane Flashcards
What is the job of cholesterol in the plasma membrane?
Give stability
What is the job of carbohydrates in the plasma membrane?
Cell-cell recognition
What is the job of proteins in the plasma membrane?
Receptors, transporters, attachments
protein that goes all the way through the membrane
Integral membrane
proteins that is on one side of the membrane
Peripheral protein
protein that transports in and out of the cell
Transport protein
protein that is a receptor for signal transduction
Receptor protein
What four structures are found in all cells?
- plasma membrane
- cytoplasm
- organelles
- DNA
What is the cell theory?
- cells are the basic structural + functional units of life
- cells can only arise from other cells
- living things are made of cells
“stitches”; impermeable junctions that prevent molecules from passing through the intracellular space
Tight junctions
“rivets/spot welds” that anchor cells together and help form an internal tension-resisting
Desmosomes
“pores” allow small molecules to pass from cell to cell to spread ions
Gap junctions
