Describe the stucture and function of Mitochondria.
Structure: Rod- or oval-shaped bodies enclosed by two membranes, with the inner membrane folded into cristae that projects into an interior matrix.
Function: Act as energy organelles; major site of ATP production; contain enzymes for citric acid cycle and electron transport chain.
Describe the stucture and function of Vaults.
Structure: Shaped like hollow octogonal barrels.
Function: Serve as cellular trucks for transport from nucleus to cytoplasm.
Describe the stucture and function of the Plasma Membrane.
Structure: Lipid bilayer studded with proteins and small amounts of carbohydrate.
Function: Acts as selective barrier between cell contents and extracellular fluid; controls traffic in and out of the cell.
Describe the stucture and function of the Nucleus.
Structure: DNA and specialized proteins enclosed by a double-layered membrane.
Function: Acts as control center of the cell, providing storage of genetic info; nuclear DNA provides codes for the synthesis of structural and enzymatic proteins and serves as blueprint for cell replication.
Describe the stucture and function of Ribosomes.
Structure: Granuels of RNA and proteins-some attached to rough ER, some free in the cytoplasm.
Function: Serve as workbenches for protein synthesis.
Describe the stucture and function of Microtubules.
Structure: Long, slender, hollow tubes composed of tubulin molecules.
Function: Maintain asymmetric cell shapes and coordinate complex cell movements.
Describe the stucture and function of Microfilaments.
Structure: Intertwined helical chains of actin molecules; microfilaments composed of myosin molecules also present in muscle cells.
Function: Play a vital role in various cell contractile systems; serve as a mechanical stiffener for microcilli.
Describe the stucture and function of Intermediate Filaments.
Structure: Irregular, threadlike proteins.
Function: Help resist mechanical stress.
Where is the enzyme Catalase located and what is it's function?
Function: Neutralizes toxin at production site (ex: peroxide)
Where are Cristae located, what is their structure, and what is their function?
Structure: Infolding shelves that project into the mitochondria.
Function: Contain crucial proteins used to convert much of the energy in food into a usable form.
What is the difference between Aerobic and Anaerobic exercise?
Aerobic is with oxygen, while Anaerobic is without oxygen.
Where does Aerobic exercise take place?
In the mitochondria.
Where does Anaerobic exercise take place?
In the cytosol.
What are the two types of Anaerobic exercise and when do they occur?
