Answer 2

Answer 1. Frog Respiration. The frog has three respiratory surfaces on its body that it uses to exchange gas with the surroundings: the skin, in the lungs and on the lining of the mouth. While completely submerged all of the frog's repiration takes place through the skin.

Answer 2. The breakdown of glucose and its successor molecules in the presence of oxygen to release energy is called aerobic respiration. For aerobic respiration, pyruvate is transported from the cytoplasm into the mitochondria.

C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

Answer 3. Human muscle cells can respire anaerobically for short periods of time. This often happens during vigorous exercise, such as 100 m sprints. The body struggles to supply the muscles with enough oxygen to keep on doing aerobic respiration but the muscles still need energy to contract.
