Aerobic Respiration (final)
This Knowledge Audit will gauge your understanding of the material for the "Aerobic Respiration" unit after instruction. Your teacher will use the information to modify, change and improve instruction as suggested by the results. Please answer each question accurately and honestly. You are scored for on time completion of the assignment, not how much you already know.

Knowledge Audit
For each statement below, indicate your level of confidence and knowledge about the statement using the following scale:

1. Very poor: you've never heard of this topic or idea.
2. Poor: you've heard this, but couldn't tell share any detailed information about it.
3. Fair: you remember the basic information about this topic or idea.
4. Good: you remember details and examples about this topic or idea.
5. Very good: you could teach others about this topic or idea.

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.
Very poor
Very good
2.8.S1: Analysis of results from experiments involving measurement of respiration rates in germinating seeds or invertebrates using a respirometer *
Outline the use of a respirometer to measure cellular respiration rate.
Very poor
Very good
2.8.NOS: Assessing the ethics of scientific research- the use of invertebrates in respirometer experiments *
List ethical questions that must be considered before using animals in experiments.
Very poor
Very good
8.2.U12: The structure of the mitochondrion 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.
Very poor
Very good
8.2.S2: Annotations of a diagram of mitochondrion 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.
Very poor
Very good
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.
Very poor
Very good
8.2.U5: In aerobic cell respiration pyruvate is decarboxylated and oxidized. *
Define decarboxylation and oxidation.
Very poor
Very good
8.2.U6: In the link reaction pyruvate is converted into acetyl coenzyme A. *
Summarize the reactant and products of the link reaction.
Very poor
Very good
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.
Very poor
Very good
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.
Very poor
Very good
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 Kreb 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.
Very poor
Very good
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 give 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.
Very poor
Very good
8.2.U11: Oxygen is needed to bind with 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 the formation of water in the matrix at the end of the electron transport chain helps maintain the hydrogen gradient between the intermembrane space and the matrix.
Very poor
Very good
8.2.U10: In chemiosmosis, protons diffuse through ATP synthase to generate ATP. *
Define oxidative phosphorylation and chemiosmosis.
Very poor
Very good
8.2.NOS: Paradigm shift- chemiosmotic theory led to a paradigm shift in the field of bioenergetics. *
State that Peter Mitchell's proposal of the chemiosmotic hypothesis in 1961 lead to a major shift in our understanding of cellular processes.
Very poor
