Aerobic Respiration

  • Aerobic Respiration Explanation
  • Aerobic vs Anaerobic Respiration

Complete Respiration Exploration Lab

  • Anaerobic cell respiration gives a small yield of ATP from glucose
  • Aerobic cell respiration requires oxygen and give a lard yield of ATP from glucose
  • In aerobic cell respiration pyruvate is decarboxylated and oxidized, and converted into acetyl compound and attached to coenzyme A to form acetyl coenzyme A in the link reaction.
  • Skill: Analysis of diagrams of the pathways of aerobic respiration to deduce where decarboxylation and oxidation reactions occur.
  • Application:Use of Anaerobic cell respiration in yeasts to produce ethanol and carbon dioxide in baking.
  • Application: Lactate production in humans when anaerobic respiration is used to maximize the power of muscle contractions.
  • Skill: Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using respirometer.

Respiration Part II

  • In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of hydrogen carriers, liberating carbon dioxide.
  • Energy released by oxidation reactions is carried to the cristae of the mitochondria by reduced NAD and FAD.
  • Transfer of electrons between carriers in the electron transport chain in the membrane of the cristae is coupled to proton pumping.
  • In chemiosmosis protons diffuse through ATP synthase to generate ATP.
  • Oxygen is needed to bind with the free protons to maintain the hydrogen gradient, resulting in the formation of water.
  • The structure of the mitochondrion is adapted to the function it performs.
  • Skill: Annotation of a diagram of mitochondrion to indicate the adaptations to its function.

Photosynthesis Introduction

Photosynthesis Exploration with Vernier

  • Photosynthesis is the production of carbon compounds in cells using light energy
  • Visible light has a range of wavelengths with violet the shortest wavelength and red the longest
  • Chlorophyll absorbs red and blue light most effectively and reflects green light more than other colors
  • Oxygen is produced in photosynthesis from the photolysis of water
  • Energy is needed to produce carbohydrates and other carbon compounds from carbon dioxide
  • Temperature, light intensity and carbon dioxide concentration are possible limiting factors on the rate of photosynthesis
  • Light-dependent reactions take place in the intermembrane space of the thylakoids.
  • Reduced NADP and ATP are produced in the light-dependent reactions.
  • Absorption of light by photosystems generates excited electrons.
  • Photolysis of water generates electrons for use in the light-dependent reactions.
  • Transfer of  excited electrons occurs between carriers in thylakoid membranes.
  • Excited electrons from Photosystem I are used to contribute to generate a proton gradient.
  • ATP synthase in thylakoids generates ATP using the proton gradient.
  • Excited electrons from Photosystem II  are used to contribute to generate a proton gradient.
  • Skill: Drawing an absorption spectrum for chlorophyll and an action spectrum for photosynthesis.
  • Application: Calvin’s experiment to elucidate the carboxylation of RuBP.

Complete Photosynthesis Exploration with Vernier

  • Light-Independent reactions take place in the stroma.
  • In the light-independent reactions a carboxylase catalyses the carboxylation of ribulose bisphosphate.
  • Glycerate 3-phosphate is reduced to triose phosphate using reduced NADP and ATP.
  • Triose phosphate is used to regenerate RuBP and produce carbohydrates.
  • Ribulose bisphosphate is reformed using ATP.
  • Skill: Design of experiments to investigate the effect of limiting factors on photosynthesis.
