Campbell's Biology, 9e (Reece et al.) Chapter 8 An Introduction to Metabolism This chapter lays the foundations for the chapters on respiration and photosynthesis. Key concepts are as follows: The laws of thermodynamics govern energy transformations by living organisms, metabolic reactions couple energy-harvesting reactions to reactions that accomplish cellular work, and enzymes increase the rates of reaction. Understanding the properties of enzymes, how they work, and how their activities are regulated is necessary to achieve an understanding of metabolic pathways. Multiple-Choice Questions 1) Which term most precisely describes the cellular process of breaking down large molecules into smaller ones? A) catalysis B) metabolism C) anabolism D) dehydration E) catabolism

9/30/2018 Entropy: Why Life Always Seems to Get More Complicated https://jamesclear.com/entropy 1/11 JAMES CLEAR Entropy: Why Life Always Seems to Get More Complicated by James Clear (staging.jamesclear.com/about)????| ???? Mental Models (https://jamesclear.com/mental-models) Murphy's Law states, ?Anything that can go wrong, will go wrong.? This pithy statement references the annoying tendency of life to cause trouble and make things difficult. Problems seem to arise naturally on their own, while solutions always require our attention, energy, and effort. Life never seems to just work itself out for us. If anything, our lives become more complicated and gradually decline into disorder rather than remaining simple and structured. Why is that?

Quantitative properties - associated with numbers Units must always be specified Scientific measurements use the metric system SI Units Seven base units are used by SI Prefixes are used to modify powers of 10 of these units Length and Mass Mass - the measure of the amount of material in an object Temperature - a measure of hotness and coldness (physical property) Heat flows spontaneously from the hotter object to the colder one Celsius scale - created considering water's boiling and freezing points Kelvin scale - created so that 0K is the lowest possible attainable zero (absolute zero) The Kelvin and Celsius scales use the same-sized units around a different zero Derived SI Units - obtained by the multiplication or division of one or more base units

Kavya Immanni Mrs.Rothfuss Honors Biology I / 3B 2, February 2017 5:1 Energy and the World of Life Notes I. Energy Disperses A. First law of thermodynamics:? Energy cannot be created or destroyed B. Energy can be converted into different forms C. Potential energy:? capacity to cause change because of where an object is located or how parts are arranged 1. Example: ATP has P.E. because of the chemical bonds that hold its atoms in certain arrangements. In muscle cells, the chemical energy of ATP is transferred to myosin. ATP is converted to kinetic energy D. Kinetic Energy: ?energy of motion E. Energy tends to disperse spontaneously, each form of energy disperses until no part of a system holds more energy than it

Composed mainly of nonmetallic elements with simple formulas and low molar masses. Unlike liquids and solids, gases expand to fill their containers. are highly compressible. have extremely low densities. Two or more gases form a homogeneous mixture. Gases ? 2015 Pearson Education, Inc. 2 Properties Which Define the State of a Gas Sample Temperature Pressure Volume Amount of gas, usually expressed as number of moles Having already discussed three of these, we need to define pressure.

Charles's law

Gas Laws -study the relationships that exist between pressure, volume, temperature and amount (moles) of gas. Boyle?s Law Pressure-volume relationship At constant temperature and amount, the pressure and volume of a gas are inversely proportional. As pressure increases, volume decreases. P1V1=P2V2 Charles? Law Temperature-volume relationship At constant pressure and amount, the temperature and volume of a gas are directly proportional. V1/T1=V2/T2 Gay Lussac?s Law Pressure-temperature relationship Under conditions of constant volume and amount, the temperature and pressure of a gas are directly proportional. P1/T1=P2/T2
