BIOL 101 1nd Edition Lecture 35 Outline of Last Lecture I Nervous System II Central Nervous System III Peripheral Nervous System IV Nervous Tissue V Neurons VI Action Potentials VII Neurotoxins Outline of Current Lecture I Plants II Cellular Respiration III An Overview of Energy Processing Current Lecture Plants are home to the molecular beginnings of all food Why can we make this statement Plants do photosynthesis they take the atmospheric co2 and make organic molecules they reduce co2 to glucose Know the light reaction be able to explain it and what happens in it Glucose 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 molecules Glucose also used to make DNA nucleotides Plants perform cellular respiration along with animals Why do plants need O2 it s the final electron acceptor in cellular respiration That s why when you over water your plants it prevents them from absorbing O2 which prevents them from completing cellular respiration Defend this statement the bulk of our diet is composed of tissues of other organisms they are made up of cells Know 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 differently
