    In our planet Earth’s 4.6 billion years of age, oxygen became available about 2.3 billion years ago. Therefore, there must have been fermentation used by early bacteria species since there was no oxygen availability.

    \(\mathrm{ATP}\) (adenosine triphosphate) is the main energy resource of cells and product of cellular respiration and fermentation. Lastly, it will be critically important to study plant respiration since it may be enhanced under increasing carbondioxide levels and temperatures.

    \(\PageIndex{1}\). Student Learning Outcomes (SLOs)

    • SLO 17.01: Apply the best practices for learning cellular respiration
    • SLO 17.02: Describe the characteristics of three main stages of cellular respiration
    • SLO 17.03: Explain the stage of cellular respiration that produces the most \(\mathrm{ATP}\)
    • SLO 17.04: Describe the characteristics of mitochondria
    • SLO 17.05: Identify given plant species with their scientific names based on their key features
    • SLO 17.06: Explain the differences between cellular respiration and fermentation
    • SLO 17.07: Explain the differences between substrate level and oxidative phosphorylation

    \(\PageIndex{4}\). Test Your Knowledge

    • Assessment 1: TRUE or FALSE: Mitochondria exist in all cells and originated by a bacteria engulfed by eukaryotes
    • Assessment 2: TRUE or FALSE: Plants also do respiration using glycolysis, Krebs cycle, oxidative phosphorylation mostly during the night as well as photo-respiration
    • Assessment 3: TRUE or FALSE: While anaerobic respiration produces \(2 \mathrm{~ATP}\), aerobic respiration produces up to \(32 \mathrm{~ATP}\)
    • Assessment.4: TRUE or FALSE: Lenticels pores in the stem / bark of trees involve gas exchange extensively
