Human Physiology! Please fill out the following about Cells for a thumbs up rating!

Hydrophilic vs. Hydrophobic(examples, characteristics) Lipid belayed structure(think of the terms above) Cellular structures/organelles Nucleus Golgi Apparatus Endoplasmic Reticulum (Smooth and Rough) Lissome Vesicles Ribosome's (Free and bound) DNA(deoxyribonucleic acid ) structure Replication(important enzymes, direction) Why is DNA important? RNA(ribonucleic acid) Structure Types (tRNA,rRNA,mRNA) why is RNA important Protein subunits structure (Primary, secondary, Tertiary)R-groups Transcription, Translation Where does each start? Important molecules /sequences Where do they occur? Cytoplasmic vs. Tran membrane and Lysosomal proteins Diffusion and Osmosis

Explanation / Answer

Lipid bilayer structure
composed of 2 layers of fatty sheets , with the hydrophobic tails directing toward the center of the sheet.

Cellular structure / organalles
Nucleus : bounded by nuclear envelope which is double membrane , it consists of phospholipids which form a lipid bilayer nucleus also contain pore through which molecules move in and out

Endoplasmic reticulum : Ribosomes are attached to the membrane of the Endoplasmic reticulum, making it rough while lack of ribosmes make it smooth

Lysosome : spherical bodies, or vacuoles which are enclosed by a single membrane

Ribosome : a cellular machine which is complex. form up dozens of different proteins as well as a few specialized RNA molecules known as rRNA

DNA STRUCURE
DNA is double helix, composed of 2 chains or strands, of nucleotides which are held together by hydrogen bonds

DNA ENYZMES IN DIRECTION
DNA Polymerase I
DNA Polymerase III
primase
DNA helicase
SSBP
Topoisomerase
DNA gyrase
DNA ligase
Initiator protein

DNA is important because It makes us alive and unique. DNA guides the cells how they have to function. Without the DNA , no cell division and growth is possible.

Hydrophilic Hydrobhobic Example Polar covalent compounds like alcohal oils, fats Charchterstics Dissolve more readily in water than Hydrobhobic solvents cluster together in water forming micelles
