Q1. Many poisons function by blocking certain steps in metabolic pathways. For example, cyanide blocks the last step in the electron-transport chain. Explain why this blockage causes death.
Q2. Thyroid hormone increases the activity of the sodium-potassium pump. If a person produced excess amounts of thyroid hormone, how would basal metabolic rate, body weight, and body temperature be affected? How would the body attempt to compensate for the changes in body weight and temperature?
