Voet 980 solutions Where did the first ATP come from?The Earliest Cells Probably Produced ATP by Fermentation
In the process of fermentation, ATP is made by a phosphorylation event that harnesses the energy released when a hydrogen-rich organic molecule, such as glucose, is partly oxidized (see Figure 2-72).
When did cellular respiration evolve?Abstract. The origin of oxygenic photosynthesis in Cyanobacteria led to the rise of oxygen on Earth ~2.3 billion years ago, profoundly altering the course of evolution by facilitating the development of aerobic respiration and complex multicellular life.
Which likely came first in the evolution of metabolism fermentation or oxidative phosphorylation?Fermentation likely preceded oxidative phosphorylation as a mechanism for generating energy.
Which of the following directly produces the most ATP per mole of glucose during aerobic cellular respiration?Explanation: The electron transport chain generates the most ATP out of all three major phases of cellular respiration. Glycolysis produces a net of 2 ATP per molecule of glucose.
