BIOL 101 1nd Edition Lecture 35 Outline of Last Lecture I. Nervous SystemII. Central Nervous SystemIII. Peripheral Nervous SystemIV. Nervous TissueV. NeuronsVI. Action PotentialsVII. NeurotoxinsOutline of Current Lecture I. PlantsII. Cellular RespirationIII. An Overview of Energy ProcessingCurrent LecturePlants are home to the molecular beginnings of all foodWhy can we make this statement?Plants do photosynthesis, they take the atmospheric co2 and make organic molecules – they reduce co2 to glucoseKnow the light reaction be able to explain it and what happens in itGlucose is strung together to make starch and cellulose (macromolecules)These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Glucose can be modified to make other monosaccharaides and disaccharides Glucose used to build fat moleculesGlucose also used to make DNA nucleotidesPlants perform cellular respiration along with animalsWhy do plants need O2 -> it’s the final electron acceptor in cellular respirationThat’s why when you over water your plants it prevents them from absorbing O2 which prevents them from completing cellular respirationDefend this statement: the bulk of our diet is composed of tissues of other organisms – they are made up of cellsKnow the macromolecules digested at each point in the digestive system and the enzyme that goes along with it. Mouth – carbohydrate ; amylase breaks it down ; Stomach – proteins ; pepsin breaks it down ; Small Intestine – lipids ; lipase and bile breaks it down Small Intestine – nucleic acids ; nuclease breaks it down. Which organelle would you expect to find an abundance of in cells actively secreting enzymes – ribosomes attached to the rough ER on the rough ER ribosomes produce proteins that are SECRETED. What makes an epithelial cell found in the mouth different from an epithelial cell found in the small intestine?They have the same DNA and alleles but they have different proteins, meaning they express different genes. This would allow them to function
