Biology Chapter 6 notes During cellular respirations: electrons are transferred to oxygen as carbon-hydrogen bonds of gloces are broken & hydrogen-oxygen bonds of water form Glucose loses hydrogen atoms as it is converted to carbon dioxide Oxygen gains hydrogen atoms in being converted to water Redox reaction: Electron transfer requires redox reactions for electrons to lose potential energy + release energy Oxidizing glucose: NAD+, dehygrenase Electron transport chain: electrons falling from glucose to oxygen, the transfer of electrons from an organic molecule to NADH Cellular respiration: Glycolysis (cytosol): break glucose into two molecules of pyruvate net product: NADH + ATP

mitochondrion

Mitochondria are bounded by a double membrane. Each of these membranes is a?phospholipidbilayer with embedded proteins. The outermost membrane is smooth while the inner membrane has many folds. These folds are called cristae. The folds enhance the "productivity" of cellular respiration by increasing the available surface area. The double membranes divide the mitochondrion into two distinct parts: the intermembrane space and the mitochondrial matrix. The intermembrane space is the narrow part between the two membranes while the mitochondrial matrix is the part enclosed by the innermost membrane. Several of the steps in cellular respiration occur in the matrix due to its high concentration of enzymes.

STUDY GUIDE FOR CELLULAR RESPIRATION Cellular Respiration: Transfer of energy from organic compounds (especially GLUCOSE) to ATP. AEROBIC: cellular respiration WITH O2 ANEROBIC: cellular respiration WITHOUT O2 TWO STAGES OF CELLULAR RESPIRATION: STAGE 1: Glucose is converted to Pyruvate producing small amounts of ATP and NADH. STAGE 2: If O2, then: PYR and NADH make lots of ATP; if no O2, then Lactate or Ethanol and CO2 are produced. SEE FIGURE 10 FROM PAGE 104 IIN THE TEXTBOOK.

Campbell's Biology, 9e (Reece et al.) Chapter 9 Cellular Respiration and Fermentation This is one of the most challenging chapters for students to master. Many students become overwhelmed and confused by the complexity of the pathways, with the multitude of intermediate compounds, enzymes, and processes. The vast majority of the questions in this chapter address central concepts rather than details of these pathways. Other questions have accompanying figures that provide details for reference and ask students to interpret or use these models. Overall, the emphases are on the inputs and outputs of each pathway, the relationships among these pathways, the cellular locations, redox as a central principle in respiration, and chemiosmosis.

AP Biology R-11 Essential Knowledge: Ch 10 Photosynthesis 10.1 Photosynthesis converts light energy to the chemical energy of food Autotrophs (producers) make their own organic molecules (food) from inorganic substances; heterotrophs (consumers) obtain their organic molecules by eating other organisms Plants are autotrophs that make their own organic molecules via photosynthesis Photosynthesis converts radiant energy (sunlight) into chemical energy (glucose) Photosynthesis occurs in the chloroplasts Leaves are the major site of photosynthesis in plants Chlorophyll is a green pigment found in the chloroplasts; it is the chlorophyll that actually absorbs the light energy Tiny pores on the underside of leaves, called stomata, are where CO2 enters and O2 exits

ENERGY Physiology Function:worklive -grows(mitosis) -reproduce(meiosis+fertilization) -metabolism(photosynthesis and respiration) -inheritance(generation) Definition of Energy 2 Laws of Energy: 1.Conservation of Energy- energy is neither created nor destroyed, only transformed(1st law) *forms of energy: solar, potential, mechanical 2.Entropy- during the transformation of energy, some energy become disordered & becomes heat(2nd law) *heat: ?disordered energy? Coupled Reactions and Chemical Bonds *?coupled?: with partner *coupled reactions= redox reactions 1.Reduction- gains electrons -creates chemical bond -stores energy in molecule -Photosynthesis(anabolic) 2.Oxidation-loses electrons
