  • 9.1 How do cells use E?Cell Processes make new molecules, build membranes and organelles, maintain homeostasis (active transportation).

    Body Processes muscle contraction, digestion, brain control

  • 9.1 Where does your body get E?You EAT!Carbohydrate, Lipids, and Proteins ALL get broken downHIGH E bonds in Carbs and LipidsAll break down and eventually makeATP (adinosine triphosphate) quick E for the cell

  • 9.1 How does ATP work?E is stored in the BONDS.

    Each bond in ATP has more and more E.

    Break a bond and E is released.

  • 9.1 Why is ATP so useful?RECHARGABLE: ADP is like a rechargeable battery that is lowyou can recharge it by putting another phosphate group on it. This alleviates the need for a cell to store large quantities of ATP (no space)As long as phosphates are available you can recharge.

  • 9.1 How do cells get the E from ATP. Proteins have special sites for ATP to bind.E is usedAfter the 3rd P breaks off ADP is released

  • ATP

  • 9.3 What is Cellular Respiration?The process of mitochondria (power station of the cell) to break down glucose (from food) to make ATP.

    There are 3 stages:GlycolysisCitric Acid/ Krebs Cycle Electron Transport Chain (ETC)

  • 9.3 What is Glycolysis?Anaerobic Location: CytoplasmUses: GlucoseMakes: a little ATP and Pyruvic Acid

  • What is the Citric Acid Cycle?Location: MitochondriaUses: Pyruvic AcisMakes: a little ATP and electrons and CO2

  • What is the e- Transport Chain Aerobic Location: Inner Mito. membraneUses: electrons from CACMakes: A LOT of ATP and water

  • What is fermentation?When NO oxygen is present.Glycolysis still happens, but next step is FERMENTATIONEssentially makes enough E to run glycolysis Lactic Acid FermentationUsed by animal cellsProduces lactic acid and 2 ATPAlcoholic FermentationUsed by yeast and some bacteriaProduces CO2 and ethyl alcohol

  • What is photosynthesis? sunlight 6 CO2 + 6 H2O C6H12O6 + 6 O2

    Job = take suns E and convert it into into something storable, such as sugar/starch

  • Where do the reactions take place?www.biologycorner.com/resources/photosynthesi...

  • 9.2 What is Photosynthesis?Photosynthesis-Creates food/energyBase of food chain in plant material (producers)Creates O to breathe O is a byproductEliminates CO2CO2 is taken in

  • 9.2 Describe the reactions of photosytnesisLight Dependent Rxn.Uses light and water to create ATP and O2 (we breath this)Light Independent Rxn. (Calvin Cycle)Uses ATP and split water from LD to create sugars (usable E)upload.wikimedia.org/wikipedia/commons/a/a3/S...
