Students have asked these similar questions
A student lists some characteristics of anaerobic respiration.
1. It produces 36 molecules of ATP.
2. It uses oxygen to produce energy.
3. It occurs in the cytoplasm of the cell.
4. It results in the production of lactic acid.
Which characteristics did the student list incorrectly?
Characteristics 2 and 3 are incorrect because anaerobic respiration produces
energy without oxygen and occurs in the mitochondria of a cell.
Characteristics 1 and 4 are incorrect because anaerobic respiration produces 2
molecules of ATP and does not produce lactic acid.
Characteristics 3 and 4 are incorrect because anaerobic respiration occurs in
the mitochondria of a cell and does not produce lactic acid.
O
Characteristics 1 and 2 are incorrect because anaerobic respiration produces 2
molecules of ATP and produces energy without oxygen.
Fossils of a microscopic organism are found in rocks determined to be from a past era of time.
Identify TWO types of evidence that would help answer the question of whether the organism was
able to undergo aerobic cellular respiration.
Considering the negative aspects of anaerobic respiration, how could natural selection have produced something so inefficient?

- Place the five metabolic types in the probable order of their evolution: oxygenic photosynthesis, aerobic metabolisms, anaerobic chemolithoautotrophy, anaerobic chemorganoheterotrophy, anoxygenic photosynthesis. You are expected to justify your answers by identifying the origins of the energy, the carbon used and the redox couples (electron donors and acceptors). Describe the environmental conditions that probably led to the evolution of the next metabolism.arrow_forwardPut the following steps in chronological order based upon what you would do to determine if an organism can perform cellular respirationarrow_forwardSome scientists claim that aerobic respiration would have never evolved if it were not for photosynthetic microbes. Why may this be true?arrow_forward
- In analyzing all the steps of cellular respiration, which step would you consider the most important and which step the least important. Give reasons to justify the steps you have chosen.arrow_forwardBesides carboxylation, the Calvin Cycle enzyme rubisco can also react with O2 (e.g. oxygenation). The wasteful oxygenation reaction of rubisco is explained by the enzyme developing at time when there was very little O2 in the atmosphere. Since it was developed, why hasn’t rubisco evolved to get rid of the oxygenation reaction? A. Mutations that decrease the affinity of rubisco for O2 probably also decrease the enzyme’s ability to bind CO2. B. Evolution takes time; and since rubisco is found only in eukaryotes, it evolved recently. C. Since it still generates one molecule of 3-phosphoglycerate (PGA), the oxygenation reaction is actually not that wasteful. D. Because in the past few million years the concentration of CO2 in the atmosphere has risen to be much greater than the concentration of O2.arrow_forwardThe anaerobic, chemoautotrophic archaeobacterium Methanococcus jannaschii uses which of the following carbon-fixation pathways to obtain organic carbon from CO2? the Hill reaction the reductive acetyl-CoA pathway the Calvin cycle oxygenic photosynthesis the Krebs cyclearrow_forward
