Anabolic reactions require energy to occur. State two examples of anabolic reactions that take place in living organisms.
Describe and explain how ATP is used in glycolysis.
In the early 20th century, some factory workers were exposed to chemical X and suffered severe side-effects. Exposure to chemical X can cause: • reduced ATP production • greater lipid metabolism, leading to weight loss • more pyruvate and lactate being produced • release of excess heat energy, which raises body temperature and may be fatal. Chemical X makes the inner mitochondrial membrane more permeable to protons (hydrogen ions), so some protons leak into the matrix.
Explain why exposure to chemical X leads to: • decreased ATP production • increased lipid metabolism.
Suggest and explain why chemical X leads to greater production of pyruvate and lactate.
Suggest why so much heat energy is given out.
Explain why exposure to chemical X leads to: • decreased ATP production • increased lipid metabolism.
Suggest and explain why chemical X results in more pyruvate and lactate being produced.
Suggest why heat energy is released in excess.
