 WEEK ONE: AUGUST 22 - AUGUST 26: MONDAY: Intro/Orientation: Important Syllabus Reminders:  Office 225 A Holt; M/W 9:30 ­ 11:30 a.m.  Drop Lowest Quiz (Count Top 10); Quizzed on Previous Day Lecture  Material  Random In­Class Writing Assignments; Drops Lowest  4 Exams, 50 pts ea., No Makeup/Early Exams, ONLY Excused, No  Unexcused Misses; If Better Grade Received on Final, Replacement  on Lower Test  Don't MEMORIZE, Do UNDERSTAND  Include Name and "Bio 1130" in Emails to Teacher   Introduction to Chapter 6; Cell Communication:  Multicellular organisms are made of different cells with different  functions to work together  What Type of Cells Need to Communicate? o Cells within the organism to maintain Homeostasis o Cells of organisms within same species by secreting chemical  signals (ex. Biofilm) o Cells of organisms in different species or kingdoms (ex.  Signals of spores to attach to biofilm; Tobacco releases bad  chemicals to ward off insect egg laying)  4 Processes of Cell Signaling (Cont. on Wednesday) o Sending a Signal o Receiving a Signal o Transduction o Response      FOR WEDNESDAY: Obtain Scantrons, Continue Chapter 6.   WEDNESDAY: Cell Communication:  Cells can be: o Physically close o Over long distances  (ex. Hormones released from pituitary  gland in head and sent to kidneys)    How Cells Communicate (Most cells can BOTH send and receive  signals) o Signaling cell makes molecules to send out o Signaling molecule transfers information o Receptor binds with signaling molecule o Target cell with receptors receives and responds to signal  4 Main Processes of Cell Signaling o Cell must send signal through… i. Direct Contact (ex. Embryo development, immune  system) ii. Neurotransmitters diffuses across synapses (Uses  Neurons: nerve cell, conducting cell) (ex. Dopamine and  Serotonin) iii. Hormones synthesized by glands or specialized cell and transported a long distance to target cell o Another cell receives signal; Reception i. ONLY molecules that fit the specific shape of a receptor  can trigger a response. ii. Different cells have different receptors, can regulate  (increase or decrease the number of) receptors  Decreasing receptors means sending them to  lysosomes to be destroyed iii. Individual cells make many different kinds of receptors iv. The same signal can have different meanings (ex.  Epinephrine (Adrenaline): Causes heart beat increase, causes  liver to release more glucose) v. Hydrophilic (water loving) signaling molecules bind on  outside, Hydrophobic (Non­water loving) or extremely small  cells bind on inside by passing through plasma membrane vi. Plasma membrane is a phospholipid bi­layer vii. Intracellular molecules either bond through cytosol or  DNA Receptors. viii. Most intracellular receptors are:  Transcription factors (a segment of DNA is  transcribed into RNA) ix. Signaling molecules binding to receptors changes the  shape of the receptor in order to begin a response (ex. Ion  channels opening or closing, adding phosphates  (Phosphorylation) to help transfer signal x. Transmembrane receptor ­ receptors with both internal  and external parts xi. Kinase ­ enzymes that cause the transfer of phosphate  groups (ex. Protein kinases) o Converts external signal to internal signal; Transduction i. Signal is passed through a sequence of molecules (relay molecules), Usually involves kinases  Relay molecules are produced in larger  concentrations when receptors are activated to aid in  signal amplification. ii. Signaling pathways (Signaling cascade) can be turned  on or off and are regulated by adding or subtracting phosphate groups  Must be inactivated shortly after passing one  signal in order to transfer new signals  Malfunctions in these pathways may cause  serious diseases iii. The signaling molecule acts as first messenger, relay  molecules act as second messengers  Signaling molecules ­­­­> Relay molecules o Response i. Signaling molecules activate signal transduction  pathways that bring on a response ii. Signal can be amplified; Most molecules come in small  concentrations, but can bind to a receptor that changes shape  and activates many other second messengers to activate 1 or  more protein kinases, which produces it in large quantities in  relation to the start.  Fast response mechanism (ex. Epinephrine) iii. Signal MUST be terminated; The receptor and all pieces  of the pathway have to inactive so that they can respond to a  new signal.  iv. Three Types of Cellular Responses:  Ion Channels open/close (ex. Neurotransmitters)  Alteration in Enzyme Activity (ex. Binding on  receptors of white blood cells to make them attack bad  cells)  Gene Activity Turned On/Off   Cortisol passed through plasma membrane of  liver cells to change protein and fat into glucose)   Types of Response Pathways:  Pathway leads to single response  Pathway branches, leading to two or more responses  One pathway activates/inhibits another pathway (Cross Talk)  Different receptor, different response      Writing Assignment for Friday: Spend about 1hr, Explain how one  of these diseases is a result of faulty cell communication: Diabetes Multiple Sclerosis Autism Hyperthyroidism   FRIDAY: Cell Communication:  How to turn off a signal pathway: o Silence the signaling molecules i. Endocytosis ­ Process by which cells absorb molecules  to be destroyed by lysosomes o Silence the receptor i. Downregulation ­ sent to lysosomes to be destroyed  then exocytosis o Silence the molecules activated by the receptor i. Inhibit signals from being sent to a second messenger  Evolution of Cell Communication o Some signal transduction pathways found in most  organisms are very similar (highly conserved)  WEEK TWO: AUGUST 29 - SEPTEMBER 2: MONDAY: Energy and Metabolism: WEDNESDAY: Energy and Metabolism: FRIDAY: Energy Releasing Pathways:  WEEK THREE: SEPTEMBER 5 - SEPTEMBER 9: MONDAY: NO CLASS WEDNESDAY: Energy Releasing Pathways: FRIDAY: Photosynthesis:  WEEK FOUR: SEPTEMBER 12 - SEPTEMBER 16: MONDAY: Photosynthesis: WEDNESDAY: EXAM ONE FRIDAY: Plant Structure:  WEEK FIVE: SEPTEMBER 19 - SEPTEMBER 23: MONDAY: Plant Structure: WEDNESDAY: Leaf Structure: FRIDAY: Leaf Structure/Stems:  WEEK SIX: SEPTEMBER 26 - SEPTEMBER 30: MONDAY: Stems and Plant Transport: WEDNESDAY: Roots and Mineral Nutrition FRIDAY: Roots/Plant Growth and Development  WEEK SEVEN: OCTOBER 3 - OCTOBER 7: MONDAY: Plant Growth Development WEDNESDAY: EXAM TWO FRIDAY: Animal Development  WEEK EIGHT: OCTOBER 10 - OCTOBER 14: MONDAY: Animal Structure WEDNESDAY: Animal Structure FRIDAY: Protection, Support, Movement  WEEK NINE: OCTOBER 17 - OCTOBER 21: MONDAY: NO CLASS WEDNESDAY: Protection, Support, Movement FRIDAY: Neural Signaling  WEEK TEN: OCTOBER 24 - OCTOBER 28: MONDAY: Neural Signaling WEDNESDAY: Neural Regulation FRIDAY: Neural Regulation  WEEK ELEVEN: OCTOBER 31 - NOVEMBER 4: MONDAY: Sensory Systems WEDNESDAY: EXAM THREE FRIDAY: Internal Transport  WEEK TWELEVE: NOVEMBER 7- NOVEMBER 11: MONDAY: Internal Transport WEDNESDAY: Immune System FRIDAY: Immune System  WEEK THIRTEEN: NOVEMBER 14- NOVEMBER 18: MONDAY: Gas Exchange WEDNESDAY: Gas Exchange FRIDAY: Processing Food  WEEK FOURTEEN: NOVEMBER 21- NOVEMBER 25: MONDAY: Processing Food WEDNESDAY: NO CLASS FRIDAY: NO CLASS  WEEK FIFTEEN: NOVEMBER 28- DECEMBER 2: MONDAY: Osmoregulation WEDNESDAY: Osmoregulation FRIDAY: Endocrine Regulation  WEEK SIXTEEN: DECEMBER 5 - DECEMBER 9: MONDAY: EXAM FOUR WEDNESDAY: NO CLASS FRIDAY: CUMULATIVE FINAL EXAM
