Biology 198 Lab Final Exam Questions and Correct Answers

The krebs cycle occurs: inside the mitochondria the series of membrane bound proteins and cytochromes that couple ATP production with the movement of electrons in the mitochondrial membranes is called Electron transport system cellular respiration in the absence of molecular oxygen is called anaerobic cellular respiration in the presence of molecular oxygen is called aerobic most fish and many invertebrates have this type of gas exchange system gills the organism the we expect to use to demonstrate the rate of aerobic respiration are seeds and mealworms most insects have this type of gas exchange system tracheal tubes the term - Change in p/D in Fick's law of diffusion represents what concentration gradient fish gills only work in water because gills collapse in air and will stick together thin layer chromatography will be used to separate the different pigments in a plant extract in photosynthesis the series of reactions that only occur in the light are called light dependent a key molecule in photosynthesis that can capture light energy chlorophyll in higher plants photosynthesis occurs inside the chloroplasts the wavelengths of light that are most useful for photosynthesis are violet-blue and orange-red sugars are formed from carbon dioxide and water in the calvin cycle the measure of light intensity that we will use in our experiments is called photosynthetic photon flux density (PPFD) The aquatic plant we will use in our experiments is Elodea In our photosynthesis experiments we will use the spectrophotometer to determine the absorbance spectrum of a chlorophyll solution In the typical cell cycle, the period known as interphase is compose of G1, S, and G2 During the S-Phase of a cell cycle the chromosomes replicate During metaphase of a cell the chromosomes line up on the metaphase plate in a meiotic cell division, homologous chromosomes pair up in a process called synapsis In humans, Down's syndrome is a result of nondisjunction
