Note Packet

Lesson Topic Statement(s) and Objective(s) Activities
1 Mitochondria

8.2.U12:  The structure of the mitochondria is adapted to the function it performs

  • Outline how mitochondria structure could evolve through natural selection.

  • State evidence that suggests mitochondria were once free living prokaryotes.

 

8.2.S2:  Annotations of a diagram of mitochondria to indicate the adaptations to its function

  • Draw and label a diagram of the mitochondria.

  • State the function of the following mitochondrial structures:  outer membrane, inner membrane, cristae, intermembrane space, matrix, ribosome and mtDNA..


8.2.A1:  Electron tomography used to produce images of active mitochondria

  • State that electron tomography enables scientists to view the dynamic nature of mitochondrial membranes.

2 Review glycolysis and Linking Reaction

8.2.U5:  In aerobic cell respiration pyruvate is decarboxylated and oxidized

  • Define decarboxylation and oxidation.


8.2.U6:  In the link reaction pyruvate is converted into acetyl coenzyme A.

  • Summarize the reactant and products of the link reaction.

3 Kreb’s Cycle

8.2.U7:  In the Krebs cycle, the oxidation of acetyl groups is coupled to the reduction of electron carriers, liberating carbon dioxide 

  • State that NADH and FADH2 are electron carriers formed during the Krebs cycle.

  • Outline the events of the Krebs cycle, referencing the formation of NADH and FADH2, formation of ATP and decarboxylation of acetyl groups.


8.2.S1:  Analysis of diagrams of the pathways of aerobic respiration to decide where  decarboxylation and oxidation reactions occur.

  • State that decarboxylation of glucose occurs in the linking reaction and Krebs cycle of aerobic respiration.

4 Electron Transport Chain

8.2.U8:  Energy released by oxidation reactions is carried to the cristae of the mitochondria by reduced NAD and FAD

  • State that NAD+ is reduced to become NADH in the link reaction and Krebs cycle.

  • State that FAD is reduced to become FADH2 in the Krebs cycle.

  • State that NADH and FADH2 carry electrons to the electron transport chain on the mitochondrial inner membrane. 


8.2.U9:  Transfer of the electrons between carriers in the electron transport chain in the membrane of the cristae is coupled to proton pumping.

  • State that at the electron transport chain, FADH2 and NADH given electrons to electron carrier proteins.

  • State that the movement of electrons through electron carrier proteins in the electron transport chain is used to pump protons (H+) across the inner mitochondrial membrane into the intermembrane space.


2.8.U4:  Aerobic cell respiration requires oxygen and gives a large yield of ATP from glucose

  • Compare the total amount of ATP made from anaerobic and aerobic respiration. 

  • State the location of aerobic respiration.


8.2.U11:  Oxygen is needed to bind with the free protons to maintain the hydrogen gradient, resulting in the formation of water

  • State that oxygen is the final electron acceptor in aerobic cellular respiration.

  • State that that formation of water in the matrix at the end of the electron transport chain helps to maintain the hydrogen gradient between the intermembrane space and the matrix.

5 Chemiosmosis

8.2.U10:  In chemiosmosis protons diffuse through ATP synthase to generate ATP.

  • Define oxidative phosphorylation and chemiosmosis.


8.2.NOS:  Paradigm shift-chemiosmotic theory led to a paradigm shift in the field of bioenergetics.

  • Peter Mitchell’s proposal of the chemiosmotic hypothesis in 1961 lead to a major shift in our understanding of cellular processes.
