Cell division
Transcription
DNA to mRNA
Translation
mRNA to protein
In the ribosomes
Uses tRNA to bring codons
Assembly Line of Cell
Endoplasmic Reticulum
Smooth ER
Make lipids
Release out of cell
Rough ER
Ribosomes attached to it
Make proteins
Release out of cell
Worker Bees of Cell
Ribosomes
Cytoskeleton
Structure of cell
Made of proteins
Microtubules and actin
Why are proteins important?
Receptors, transport
Why are lipids important?
Semipermeability
Phospholipid bilayer
Phospholipid Bilayer
Hydrophilic heads= water loving
Hydrophobic tails= water hating
Semipermeable membrane
Eukaryotes
Membrane bound organelles
Plants, fungus, humans
Prokaryotes
Bacteria, archea
No membrane bound organelles
Have ribosomes
Virus
Need a host, not living, zombie
Not prokaryote or eukaryote
Autocrine Signaling
Self secreting
Act on self
Paracrine Signaling
Between direct neighbors
Hormonal Signaling
Secrete into blood stream to target cells
Neurotransmitter Signaling
By neurons into synaptic cleft
Neurohormonal Secretion Signaling
By neurons through the blood
Mitosis
Asexual cells
Diploid to Diploid
Meiosis
Sexual cells
Diploid to haploid
What characterizes tissues?
Groups of cells with similar form and function working together
