Campbell's Biology, 9e (Reece et al.) Chapter 4 Carbon and the Molecular Diversity of Life This chapter focuses on the chemistry of carbon and organic compounds. Students should be able to identify the nature of the bonds between carbon and other elements (nonpolar versus polar), the different types of weak bonds and interactions, the various types of isomers, the basic functional groups of organic molecules, and their relative solubility in water. The abiotic formation of organic molecules from inorganic molecules is important in the origin of life. Multiple-Choice Questions 1) The element present in all organic molecules is A) hydrogen. B) oxygen. C) carbon. D) nitrogen. E) phosphorus. Answer: C Topic: Concept 4.1 Skill: Knowledge/Comprehension

Chemistry Notes in Physiology Chemistry notes in Physiology: Atoms Atom?the basic unit of an element An atom consists of subatomic particles: Proton This has a ( + ) charge The number of protons in an atom is called atomic number Neutron This has no charge Electron This has a ( ? ) charge The number of electrons is usually equal to the number of protons ? Both the proton and the neutron are in the nucleus The sum of the proton and neutron is called atomic mass Shell = energy level 1st shell has 2 electrons 2nd shell has 8 electrons Valence electrons are the outermost electrons ? Isotopes = same atomic number, but different atomic mass Isotopes will differ in the number of neutrons For example: Hydrogen has 1 proton Deuterium has 1 proton and 1 neutron

The Chemical Context of Life 8/22/13 6:23 PM Chapter 1: Exploring Life Biology?s Most Exciting Era Biology- the scientific study of life Biologists explore life from the microscopic to the global scale A Hierarchy of Biological Organization The biosphere- consists of all the environments on Earth that are inhabited by life. Ecosystems- consists of all the living things in a particular area, along with all the nonliving components of the environment with which life interacts. Ex. forest The biosphere is composed of ecosystems Communities- the entire array of organisms inhabiting a particular ecosystem. The set of populations that inhabit a particular area Populations- consists of all the individuals of a species (forms of life) living within the bounds of a specified area

Chapter 7 ? Periodic Properties of the Elements 7.1 Development of the Periodic Table ? Majority of elements discovered 1735-1843 ? Elements arranged to reflect trends in chemical and physical properties ? Periodic table arose from periodic patterns in electronic configurations o Valence orbitals o Trends in rows and columns ? Mendeleev and Meyer ? Modern periodic table 7.2 Effective Nuclear Charge Effective nuclear charge (Zeff) is the charge experienced by an electron on a many-electron atom. The effective nuclear charge is not the same as the charge on the nucleus because of the effect of the inner electrons. ? The electron is attracted to the nucleus, but repelled by electrons that shield or screen it from the full nuclear charge.

Summary of AP Bio Study Book: Barron?s AP Bio Chemistry Section The biochemistry section includes the following subjects: Atomic Structure, Bonding, Polar and Nonpolar Molecules, Hydrophobic and Hydrophilic Substances, the Properties of Water, Isomers, Organic Compounds, Energy, Enzymes, and Metabolism. Atomic Structure All atoms consist of three subatomic particles: neutrons, protons, and electrons. An atom in the elemental state always has a neutral charge because the number of protons equals the electrons. Isotopes are atoms that have the same atomic number but have a different mass because they have more or less protons than usual.

Chapter 3 Biology Outline- ?Water and the Fitness of the Environment? The polarity of water molecules results in hydrogen bonding Water is more extraordinary than people thing because water is everywhere. The unequal ?v? shape of a water molecule makes it a ?polar molecule?. Polar molecules have a positive charge on one side of the molecule and a negative charge on the other side. The polar molecules are attracted to each other (they are like magnets) and that is why water always forms droplets and stays together. Four emergent properties of water contribute to Earth?s fitness for life Cohesion Water molecules stick together due to hydrogen bonding. Cohesion contributes to the transportation of water and dissolved nutrients going against gravity in plants.
