9. Cyanide poisoning can occur from breathing smoke in a house fire or exposure to certain chemicals, like those used in metal polishes or insecticides. One sign of cyanide poisoning is muscle weakness. Another sign of cyanide poisoning is a cherry red skin color, resulting from an increased amount of oxygen-carrying hemoglobin in the veins. Normally, oxygen cycles into the cells from the hemoglobin in the arteries, so as hemoglobin moves to the veins it is usually deoxygenated. a. Which molecule do you think the body is running low on to cause muscle weakness? Explain your answer. b. What aspect of ATP synthesis might cyanide be interfering with to cause oxygen needs of the cell to decrease?

Expert Solution
Step 1

Introduction 

Cyanide poisoning is a potentially life-threatening condition that occurs when an individual is exposed to high levels of cyanide. Cyanide is a toxic chemical that can interfere with the body's ability to use oxygen, leading to cellular asphyxiation. It can be ingested, inhaled, or absorbed through the skin.
