Biology 119, Spring 2015 Review sheet for Exam 1 The exam is worth 100 points total. It will consist of approximately 47 multiple-choice questions worth 2 point each and 3-4 short essay questions. Bring a scantron and pencil to the exam. The best way to study is to review the posted lecture notes. I suggest printing of a blank copy and filling them in referring to your book and notes as little as possible. Continue this process until you can fill them in without assistance. Exam 1 will cover

PHOTOSYNTHESIS • • • • • It is the physico-chemical process on which the every existence of life on this planet depends. It is an endergonic reaction and anabolic process. It is synthesis of carbohydrates from CO2 and H2O by utilising the light energy in which O2 is the bye product. The overall reaction of photosynthesis can be represented by the equation: Light and 6CO2 + 12H2O Chlorophyll → C6 H12 O6 + 6 H2O + 6 O2 • From carbohydrates, the other organic substances of the plant

ATP Synthase – an Example for Chemical Energy Regulated Protein ATP synthase is enzyme located mainly in mitochondrial inner membrane and bacterial plasma membrane, coupled with the proton concentration gradient developed by electron transport chain carrying the synthesis of ATP from ADP and inorganic phosphate. The molecular mass of ATP synthase is around 550. The difference in molecular mass is due to different stoichiometry arrangements of subunit c, whose number ranges from 8 to 15. In Lehninger:

acid.Ligands act as Lewis bases by electron pair donation to form the metal-ligand bond.Bronsted-Lowry acid-base theory reminders (essentially a sub-set of Lewis Theory)A base is a proton acceptor.This is via an electron lone pair on the base (a Lewis base is a lone pair donor).e.g. NH3, HCO3-, OH- etc.An acid is proton donor.This involves a heterolytic breakage of an X-H bond (a Lewis acid is an electron pair acceptor).e.g. HCl, HCO3-, H2SO4, CH3COOH etc. • Many hexa-aqa complex ions can undergo

particles make up every atom? Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P." Neutrons have no electrical charge. 2. What are the major differences among the three particles that make up every atom? The three particles which make up every atom differ in electrical charge and in mass, primarily. The proton and neutron have approximately

Tanya Lewis in her Live Science article, the MRI machine uses a scanner to apply a very strong magnetic field, which aligns the proton “spins” of the water molecules’ hydrogen nuclei (protons). The scanner also produces a radio frequency current that creates a varying magnetic field. After absorbing the energy from the magnetic field, the protons flip their spins. As the protons realign, they emit different amounts of energy depending on the type of body tissue that they come from. This energy also produces

atom dari unsure yang sesuai serta jumlah yang spesifik dari atom atom ini . | Teori ini dibantah setelah penemuan adanya sub atom yang ternyata menyusun atom yaitu electron , proton dan neutron. Semua atom dapat di identifikasi berdasarkan jumlah proton dan neutron yang di kandungnya. -nomor massa = jumlah proton + jumlah neutron - nomor atom = nomor massa – jumlah neutron Table periodic ditemukan pada tahun 1800-1900 fungsinya untuk mengelompokan unsure unsure yang mempunyai sifat

differences among proton, neutron and electrons? What is isotope? Carbon has six protons, if it receives one additional proton will it be remain as carbon? If not, what would be new element? Protons are positively charged particles found in the nucleus. Neutrons are particles that have no electrical charge and are found in the nucleus. Electrons are negatively charged particles whirling around the atom. An isotope is an atom that has extra or fewer neutrons than the number of protons. If carbon gains

pass through an electron transport system to photosystem 1. There, the electrons become excited again by the absorption of light, and are ultimately transferred to NADP+ as the final electron acceptor forming NADPH. These processes establish a proton gradient

essentially the number of electrons, protons and neutrons within an atom which determines the characteristics of the element. Within the atom, strong nuclear forces hold the neutrons and protons inside the nucleus, preventing the atom from breaking apart which provides stability for the smaller elements, such as oxygen and carbon (J. Lucas, 2014). To produce stability for heavier elements, the ratio of neutrons to protons must increase as the repulsion forces between the protons increase. This increase in
