Cellular Respiration：練習問題

Which of the following substances is a product of aerobic respiration in human muscle cells?

Compare the processes of aerobic respiration and photosynthesis. Which of the following statements accurately describes the relationship between the energy changes and the gases involved in these two processes?

How does anaerobic respiration in humans differ from aerobic respiration, and what is the net gain of energy in the form of ATP?

During a period of vigorous exercise, the oxygen supply to muscle cells may become insufficient. Which of the following statements correctly describes the metabolic process that occurs under these conditions and its consequences?

A student sets up an experiment with two identical flasks: Flask A contains boiled seeds and Flask B contains germinating seeds. Both flasks are connected to a delivery tube dipping into lime water. After several hours, the student observes that the lime water for Flask B turns milky, while for Flask A it remains clear. Explain the biochemical reason for this difference and identify the source of energy being utilized by the seeds in Flask B.

During vigorous exercise, muscle cells may undergo anaerobic respiration. Evaluate why the buildup of lactic acid leads to muscle fatigue and explain how the body eventually removes this substance after exercise ceases.

A scientist measures the changes in the internal environment of a sealed flask containing germinating seeds. If the concentration of oxygen decreases while the concentration of carbon dioxide increases, and a slight rise in temperature is recorded, explain the interdependence of these three observations in the context of cellular respiration.
