- **Fermentation**: A metabolic process that converts sugar to acids, gases, or alcohol in the absence of oxygen. It typically yields a low amount of ATP (around 2 ATP per glucose molecule). - **Anaerobic respiration**: A process that uses electron acceptors Show more…

During the process of glycolysis, electrons are donated to NAD+ to form NADH, which can be used to donate electrons later. Which of the following would be the least preferred substance to gain electrons? a. SO32- b. Fumarate c. NO3- d. Fe3+ A chemoorganotroph and a photoautotroph would not be competing with each other for carbon, nitrogen, or oxygen. Which of the following metabolisms generate a proton motive force for ATP generation? Choose all that apply. Aerobic respiration Anaerobic respiration Iron oxidation Substrate-level phosphorylation Whether an organism is classified as a photoheterotroph or a photoautotroph depends on its energy source, carbon source, oxygen requirements, and respiration pathways.

Which of the following are true about anaerobic respiration, aerobic respiration, and fermentation? Group of answer choices Only aerobic respiration and fermentation use substrate phosphorylation in order to produce ATP. ATP is generated through photophosphorylation only in aerobic respiration. The pyruvate oxidation process in anaerobic respiration is the same as the pyruvate oxidation process in aerobic respiration. The Kreb cycle occurs in all three processes. Fermentation and anaerobic respiration generate the same amount of ATP in glycolysis. Under certain conditions, human muscle cells can switch from aerobic respiration to fermentation. In all three pathways, NADP is used to accept electrons from food during glycolysis. The electron transport chain in fermentation is much shorter than the electron transport chain in aerobic respiration. Anaerobic respiration and aerobic respiration harvest more energy from sugar than fermentation. The only difference between the processes of anaerobic respiration and aerobic respiration is the final electron acceptor.
