Ch5 Ch58 A Chapter questions 0 What is the general structure of the plasma membrane 0 What is the relationship between phospholipids hydrophobic and hydrophilic and lipid bilayer 1 The net movement of a substance from a region of high concentration to a region of low concentration 0 The rate of diffusion is related to molecule size kinetic energy temperature electrical charge and the concentration gradient Diffusion of molecules directly through the membrane is called Passive Transport 2 One of the most important ways of materials are moved in and out ofceHs Ii Ex Oxygen owing through the membranes of lung cells into blood cells Charged or polar acids do not pass readily through a membrane They will instead be attracted to water hydrophilic Charged and polar molecules won39t be able to pass through hydrophobic interior of the phospholipid bilayer Facilitated transport and osmosis 1 The passive movement of molecules down its concentration gradient via a channel or transport protein is called facilitated transport 2 Osmosis is the diffusion of water across a selectively permeable membrane A lsotonic solution the solute concentration is the same inside and outside of the cell Has no net movement B Hypertonic solution The solution with the higher concentration of solute If the concentration is higher outside of the cell than inside water will diffuse out of the cell via osmosis C Hypotonic solution the solution with the lower concentration of solute If the concentration of solute is lower outside the cell than inside water will diffuse into the cell via osmosis The movement of a solute across a membrane against its concentration gradient 0 Primary active requires energy to move solute against concentration gradient 0 Secondary active preexisting gradient drives active transport of another solute o Endo is the reverse of exo 1 The plasma membrane a selective permeable barrier that allows passage of oxygen nutrients and wastes for the whole volume of the cell 0 Three types of Endo A Receptormediated endocytosis B Pinocytosis Cell drinking C Phagocytosis cell eating End of Ch5 II Ch 6 Energy enzymes and metabolism A Chapter questions 0 What is energy Ch58 Page 2 of 5 I Energy is the ability to promote change or to do work With matter and opposing forces 0 Two forms of energy 1 Kinetic energy is the energy associated with movement 2 Potential energy is stored energy due to structure or loca on Cells use ATP to drive reactions a Atp is a nucleotide consisting of the sugar ribose the nitrogenous base aedine and a chain of three phosphates The ATP cycle is a renewable resource that is continually regenerated by adding a phosphate group to ADP Reactions that occur in cells are so slow that they could not contribute to life unless the cells did something to speed them up i A single enzyme can accelerate a reaction over one million times faster than the reaction would occur without the enzyme Temperature and pH affects enzyme activity Metabolism The sum total of all chemical reactions that occur within an organism 0 Two types of metabolic pathways of involving energy Cataboic pathways breakdown larger molecules into smaller ones to produce energy Hydrolysis Anaboic Synthesize larger molecules from smaller ones and requires energy to do so End of Ch 6 Ch7 Cellular respiration and fermentation Ch58 Page 3 of 5 Understand the role of the electron carriers NAD and FAD in cellular respiration A Support 1 Example 1 Example B Support 1 Example 2 Example C Support 1 Example 3 Example Ill Third main point weakest A Support 1 Example 4 Example B Support 1 Example 5 Example C Support 1 Example 6 Example 0 Redox Reactionsreactions that result in the transfer of one or more electrons from one reactant to anotherConclusion IV OILRIG Oxidation is loss reduction is gain 0 Glycolosis takes place in the cytosol and it39s the rst stage of cellular respiration and breaks down glucose It occurs in the presence of oxygen or without 0 Used 2 atp Made 4 atp 2 pyruvates and 2 NADH wghich comes to a net of 2 atp 2 pyruvates and 2 NADH Ch58 Page 4 of 5 VI VII The Krebs Cycle 2 Pyruvates3Carbons 02Krebs cycle2 acetyol CoA 2acetyol2c OxaloacetateCitate6carbons and it repeats VIII Used 2 oxaloacetate and 2 acetyol CoA Made Citrate 1 atp 3 NADH and 1 FADH Net 2Atp 6NADH and 2 FADH2 IX X The electron transport chain All of the NADH39s and FADH39s that are produced from glycolosis and the citric acid cycle go to the electron transport chain XI XII The ATP yield 0 The theoretical yield of ATP is 36 to 38 molecules A Restate topic B Revisit introduction or tie all ideas together Ch58 Page 5 of 5
