Define energy: Where does energy come from? How is ATP like change from a $100 bill? Name the 3 parts of an ATP molecule. What is the difference between an ADP molecule and an ATP molecule? Explain how an independent phosphate is like putting the top on a battery. (What happens when it is added? What happens when it is removed?) Name some things organisms use energy for. Gnature with Gnat 2015 Photosynthesis Explain why autotrophs use photosynthesis. What 4 items are necessary for photosynthesis to occur? The equation for photosynthesis: What colors make up white light? Why do chloroplasts (and therefore plants) appear green? What is chemosynthesis? Gnature with Gnat 2015 Photosynthesis Light Reactions Dark Reactions _________ part of “photosynthesis” ________ part of “photosynthesis” Location: ______________________ Location: ______________ Overview: Overview: H2O chlorophyll ATP glucose NADPH Light energy O2 Gnature with Gnat 2015 CO2 Light Reactions Dark Reactions __”Photo”__ part of “photosynthesis” (means light) _”Synthesis” part of “photosynthesis” (means to make something) Location: __thylakoid membrane_______ Location: __stroma__________ Overview: Light energy hits chlorophyll and adds energy to electrons, which are stored as ATP. Overview: Carbon dioxide (CO2) is taken in and changed into sugar. H2O molecules are broken apart and O2 is released. H+ travels on NADP+ to the dark reactions. H2O chlorophyll ATP glucose NADPH Light energy O2 Gnature with Gnat 2015 CO2 RESPIRATION What goes into the photosynthesis process: What comes out of the photosynthesis process: What goes into the cellular respiration process: What comes out of the cellular respiration process: Using the charts you filled in above, explain why cellular respiration considered to be the “opposite” of photosynthesis. Cellular respiration occurs in the __________________ of the cell. Cellular respiration always begins with what process? In this process, ___________________ is broken down into ______________ acid, hydrogen ions, and electrons. Gnature with Gnat 2015 4 molecules of ATP were produced; however, _____ were needed to start glycolysis. Therefore, the net production of ATP from glycolysis is ________ ATP. If oxygen is present after glycolysis, ____________________ respiration will take place. The first step of this process is the __________ ___________ cycle or __________ cycle. This cycle is followed by the ____________ _____________ _____________, which creates ______ ATP molecules. What is the total output of ATP including both glycolysis and the ETC? If oxygen is not available, the cell will use _______________ ________________ after glycolysis. This is also known as ______________. Name the 2 types of fermentation and list one organism that uses each type: Gnature with Gnat 2015 1 2 3 4 Gnature with Gnat 2015 1 2 3 4 Step 1: Glycolysis breaks 1 glucose molecule into 2 pyruvic acid molecules and has a net output of 2 ATP. Step 2: Pyruvic Acid releases a CO2 and forms Acetyl-CoA. (This happens with each Pyruvic Acid.) Step 3: Acetyl-CoA enters the Citric Acid Cycle, which releases CO2 and makes 1 ATP. (This happens with each Acetyl-CoA.) Step 4: High energy electrons pass from the Citric Acid Cycle to the Electron Transport Chain using NADH and FADH2. These are used to produce more ATP. O2 is the final electron acceptor, which produces H2O. At the end of the Aerobic Respiration Process, 36 ATP have been created from 1 molecule of glucose.
