Answer:
Survival of the fittest; nature "selects" the organisms best suited to their environment to survive and pass on traits. ... What role does the environment play in natural selection? Species adapt to fit their environment because a species environment is what selects for traits that are fit or less fit.
ATP is the energy coin of the cell. In cellular respiration, ATP is mainly produced by the electron transport chain (ETC) which is coupled to a concentration gradient of protons in the inner mitochondrial membrane.
- In this case, the organism above described CANNOT synthesize ATP by the electron transport chain (ETC) because it cannot generate a concentration gradient of protons (H+).
- Cellular respiration is a series of metabolic reactions used by aerobic organisms to generate ATP from foods and oxygen.
- Cellular respiration consists of three stages glycolysis, the Krebs cycle, and oxidative phosphorylation.
- In oxidative phosphorylation, the ETC is coupled to the generation of an H+ concentration gradient across the inner mitochondrial membrane, which is then used to synthesize ATP.
