13
Chemistry of Life carbon _________ __________-always contain _________ and hydrogen and usually are associated with ________ things Organic compounds that make up all living things are carbohydrates, __________, __________, and nucleic acids ______________ supply __________ for cell processes ________ are _______ or oils and do not mix with ________ and release even larger amounts of energy than carbohydrates _________ are building blocks for many structures in organisms ________ _____ are large molecules that store important _______ information in cells Organic compounds living lipids proteins carbohydrates energy Lipids fats water Proteins Nucleic acids coded
14
Chemistry of Life Inorganic compounds ___________ _________-made from elements other than _________ These compounds are the source of many ___________ needed by living things _________ is the most important inorganic compound for living things All __________ reactions in living things take place in _______ solutions carbon elements Water chemical water
15
Chemistry of Life atoms The _______ of a water molecule are arranged in a way that the molecule has areas with __________ charges The __________ part of a water molecule is attracted to the _________ part of another water molecule This attraction creates a _______ on the surface of water that can support small insects and makes water ________ This attraction also means _____________ changes of water happen ________ different negative positive film sticky temperature slowly
16
Wildcats Share Collect a red and blue colored pencil
Draw a water molecule by following the example
17
Wildcats Share Get a Chrome book and research which elements are important for good health. Looking at food labels can be a good start Shade each element you discover on the periodic table you have received

19
Moving Cellular Materials
Diffusion random ___________-the __________ movement of molecules form an area where there is relatively _______ of them to an area where there is relatively ________ of them _____________-occurs when molecules of one substance are spread _________ throughout another substance and __________ stops more fewer Equilibrium evenly diffusion
20
Moving Cellular Materials
Osmosis diffusion ___________-the __________ of water through the cell membrane Water will flow ______ of a cell when there are ________ dissolved substance outside of the cell than inside Water will flow ______ a cell when there are _________ dissolved substances outside of the cell than inside This is why plants become limp when they are not watered out more into fewer
21
Wildcats Share Describe the kinds of environments you think the cells in the below image where in and whether water was flowing into or out of them
22
Moving Cellular Materials
Facilitated diffusion proteins __________ _________-transport _________ are used to help large ___________ pass through the cell membrane Like a _____________ window at a fast food restaurant, _______ comes out and ________ goes in molecules Drive-thru food money
23
Wildcats share Imagine you go to a crowded event. You are leaving with the rest of the crowd when you realize you left something in your seat. Now you have to move against the crowd exiting to go back and get your item. Which required more energy leaving with the crowd or returning for you item? Would leaving or returning be passive transport?
24
Moving Cellular Materials
Active transport input _______ __________-occurs when an ________ of energy is required to move materials through a cell membrane _________ ________ are used which require _________ to bind with the needed particle and move it through the cell membrane ____________-process of taking substances _______ a cell by surrounding it with the ______ _________ ___________-process by which _________ release their contents _________ the cell Transport proteins energy Endocytosis into Cell membrane Exocytosis vesicles outside
