Chapter 9 notes Cellular Respiration: Harvesting Chemical Energy Concept 9.1 Metabolic pathways that release energy are called catabolic pathways - fermentation and cellular respiration _____________: partial degradation of sugars that occurs w/out the help of O2 ________: O2 is consumed as a reactant along w/ the sugar - more efficient Concept 9.1 Cellular respiration occurs in the _______________ Organic + O2 ? Carbon + H2O + Energy compounds dioxide C6H12O6 + 6O2 ? 6CO2 + 6H2O + Energy 1 glucose = -686 kcals Concept 9.1 ATP is the central molecule responsible for energy used by the cell The cell uses enzymes to transfer phosphate groups from ATP to other compounds (making them _________________) ATP ? ADP + phosphate Concept 9.1

Chapter 10 notes Photosynthesis Photosynthesis In Nature All life acquires organic compounds for energy and carbon skeletons by one of two ways - ______________: (autos = self, trophos = feed) - they sustain themselves w/out eating other organisms Photosynthesis In Nature - plants are _________________ because they use light as a source of energy - __________: (hetero = other, different) - live on compounds produced by other organisms Heterotrophs are dependent on photoautotrophs for food and oxygen Photosynthesis In Nature ________________ are the site of photosynthesis in plants All green parts of plants have chloroplasts - color is from ____________, the green pigment in the chloroplasts

IB Biology Evolution We are all related, one big family in the ?tree of life? We are not just a HUMAN FAMILY ? we are a LIVING family Evolution Do you mean the yeast are OUR distant cousins? Some thoughtful questions? What happened when scientist Paul Nurse added human DNA to the yeast cells? What does this indicate about the evolutionary history of yeast and humans? An interactive website for you to go to Standard 5.4.1 Define Evolution The cumulative change of heritable characteristics of a population Cumulative change ? small changes upon small changes that add up to large changes over long time scales and many generations! Heritable characteristics ? traits controlled by the genes Population ? not an individual 5.4.2

What are the four manners in which this book focused biologists? attention on the great diversity of organisms? What are the two points that Darwin made in his book? What is natural selection? What is the result of natural selection? In what two ways did this book ?rock the house,? in other words why was it truly radical? What was the conventional paradigm (the prevailing view) of life at the time of Darwin?s publication? Plato was one of the philosophers that had great influence on western culture. What was Plato?s view of life? How about Aristotle, what was his view? Explain the philosophy that dominated biology in the 1700s.

UNIT 15 - ECOLOGY List of Terms Ecology: study of interactions of organisms with their environment and with each other Population: group of individuals of one species in one area that can breed and interact with one another Community: all the organisms in one area Ecosystem: All the organisms in an area and abiotic factors in that area Abiotic factors: nonliving, include temperature, water, sunlight, wind, rocks, etc. Biosphere: global ecosystem Biotic potential: max rate at which a population can increase under ideal conditions Influenced by factors like age at which reproduction begins, lifespan during which you can reproduce, # of reproductive periods in lifetime, and the max # of offspring the organism can produce

Introduction: 1. Geography: study of where people, place and things are located and how they relate to each other. Location: Position on Earth?s surface Absolute location is derived from longitude and latitude. Place: Physical and human characteristics Physical: Landforms Climate Soil Animal life Human: Activities Means of transportation Religion Language Human interaction with the environment: how people alter the world around them. Hidden costs: pollution, pesticides. People?s adaptation: conformity to the land. i.e. Igloos in the north. Movement: Shift of people, goods and ideas Migration: people move to find resource/freedoms/natural disasters/war Trade: Movement of goods between areas. Resources are spread differently => import and export of goods.
