Cell Organelles

• Cell Membrane consists of

  Phospholipid bilayer

  Cholesterol

  Embedded protein

  Attached carbohydrates
• Function of the membrane

  Barrier between the inside and out of the cell

  Controls entry and exit of material

  Diffusion

  Transport

  Permeability
• Cytoplasm is the cell content
• Cytoplasm includes the organelles and cytosol
• Cytoplasm excludes nucleus
• The cytosol is the Intracellular fluid, the medium in which the cells chemical reaction take place
• Cytosol holds how many % of water

  75% - 90%
• Dissolved and suspended material of cytosol are

  Ions

  Glucose

  Amino Acid

  Lipid
• What does RNA stands for?

  Ribonucleic acid
• Ribosome is the site of protein synthesis
• Ribosomes contains ribosomal proteins
• Ribosomes can be attached endoplasmic reticulum or free in cytosol
• The 2 sub units of Ribosomes are synthesised in the nucleus then assembled in the cytoplasm
• Endoplasmic Reticulum (ER) looks like flattened sacs or tubules
• Golgi Complex looks like flatten membranous sacs bulging at edges
• What does the golgi complex do?

  Modifies and packages protein
• Example of protein GC modify?

  Lipoproteins

  Glycoproteins
• Some GC packaged protein into vesicles, one exported from cells secretory vesicles and others packages into transfer vesicles for us within the cell
• Cellular organelle containing digestive enzymes that break down materials within the cell

  Lysosome
• What does Lysosome break down?

  Worn out organelles and other cellular materials
• What type of enzymes does Lysosome contain?

  Digestive enzymes
• Cellular organelle that oxidizes organic substances for detoxification

  Peroxisome
• In which organ is Peroxisome most abundant?

  Liver
• What is Peroxisome main function

  Oxidation of organic substances for detoxification
• Mitochondria shapes like a

  Rod or bean
• What kind of membrane structure does Mitochondria have

  Double
• Membrane structure of the Mitochondria

  Smooth outer membrane

  Folded iner membrane

  inner folds
• They are energy production

  Mitochondria
• What does ATP stand for

  Adesonine Triphosphate
• Cells that are highly metabolically active have many mitochondria
• Large round or oval of a structure

  Nucleus
• Cell that does not possess a nucleus is red blood cells
• Nucleus is surrounded by nucleus envelope
