Cellular respiration
Subject:
Photosynthesis only occurs in the light on a plant but cellular respiration occurs in both light and dark and occurs on every organism

Nick Kissel Enzyme Lab 5 November 2012 Enzyme Concentration: Hypothesis: If the amount of enzymes were to increase, then more substrates will convert. Conclusion: The substrates were converted faster when there was a higher enzyme concentration. Amount of Enzymes Number of Converted Substrates after 20 Seconds 1 6 2 7 3 10 4 11 5 12 6 15 7 17 8 18 9 18 10 22 Graph 1: This graph shows the trend that when the amount of enzymes increases, so does the number of converted substrates. Substrate Concentration: Hypothesis: If the amount of substrates were to increase, then more substrates will convert. Conclusion: Spheres converted faster when there was a higher substrate concentration. Substrate Concentration

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.

Energy: Photosynthesis and Respiration
Subject:
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
