(36 cards)
What are the specialized cellular functions of metabolic absorption in the kidney?
- filter
- absorb
- excrete
Without mitochontrondia what is the process to generate ATP?
Endosymbiosis through a prokaryotic cell
What does a eukaryotic cell not have in comparison with a prokaryotic cell?
Cell wall is present in a prokaryotic cell.
What protects a bacteria cell?
Glycocalyx
What is the target of a cell for mold on eukaryotic cells?
Ribosomes
What is the problem of killing fungus?
Fungus is a eukaryotic cell, which means as you kill it you also kill host cells
Where does transcription take place?
Nucleus
Where does translation take place?
Rough endoplasmic reticulum (rough ER)
What is the primary source of smooth ER (endoplasmic reticulum)?
Liver
What is smooth ER in the liver?
Lipid metabolism/detoxification takes place here
Lysosome
Immune system role
Lyso
breakdown
or cell phagocytosis
What type of envelope surrounds a nucleus?
2 bilayer (double-membrane)
What substance permeates the nuclear envelope with ease?
Steroid goes right into a cell membrane
What cannot pass into the nucleus of a cell?
Water soluble
What comes out of the nucleus?
mRNA
What is the primary function of rough ER?
Protein synthesis
*protein folding and ER stress/inflammation
What are the functions of smooth ER?
- detoxification/lipid metabolism
2. Steroid hormone synthesis
What are some key features of the Golgi complex?
- Secretory vesicles
- Cisternae
*flat sacs with a receiving (from the ER) & exiting side
What are the functions of the Golgi complex?
REFINING PLANT = directs traffic
PSR (processes, secretes, & releases)
What all passes through the Golgi Complex?
Lipids, proteins, glycoproteins, lysosomal enzymes
What are the functions of lysosomes?
Intracellular digestion b/c lysosomes are acidic and DIGEST
What functions do lysosomes play with cellular components?
Degradation & recycling of cellular components
can even breakdown mitochondria
What process do lysosomes kill bacteria?
Phagocytosis through endocytosis (once engulfed, they present it on cell surface to promote antigen presentation)
