Chapter 3- Study Part 3 Flashcards
Where does the most ATP production occur
Mitochondria, it is thought of as cellular energy
What are functions of membrane proteins?
Integral proteins-form pores, channels,and carriers in the cell membrane.
Peripheral proteins- receptor proteins- respond to extra cellular signal.
Enzymes-catalyze chemical reactions.
Cell surface proteins-establish self.
Cellular adhesion molecules- enable cells to stick together
What hair like processes move mucus?
Cilia
What are the different types of movement through cell membranes?
LOOK ON NOTES
What are daughter cells
Formed in mitosis- a form of cell division occurring in somatic cells producing two daughter cells
What do pumps do?
Active transport pumps transport molecules from regions of low to high concentration. Sodium potassium pump- transport sodium ions out of cell and potassium ions in
What are hypertonic fluids?
Fluids that have a high osmotic pressure than body fluid.
What is another name for semi permeable membrane
Selectively permeable membrane
What structures synthesize lipids
Smooth er
Where are proteins synthesized
Ribosomes
What structures do mucus secreting cells have plenty of
Cilia
What is chromatin
Composed of loosely coiled fibers of protein and DNA that coil tightly into chromosomes during cell division
What is excess tissue fluid called
Lymph
What occurs during cell cycle
Interphase-the cell grows and maintains its routine function, DNA replication, new organelles form.
Mitosis-division and distribution of DNA to 2 daughter cells from an original.
Cytokinesis- cytoplasm divides, distributing organelles to the 2 daughter cells
