Type II: which is present in a system where oxygen is entirely absent such is possible under low oxygen concentration in the circulatory system such as the brain." For example, when a person have a stroke, the blood and oxygen supply is cut off. The brain cells being to die and the person is unable to memory thing and the muscle control is lost. In comparison, between cyanide poison and a person that had a stroke, when blood and oxygen flow or energy blockage is disrupted the body system being to shut down creates other problems such as brain dead. As for the result of the authors studies, the cyanide poison was presents that cause a deficiency in the DNA repair. The authors stated in their conclusion, " When oxidative stress is induced, reduction in ATP production will cause GP6DH to withdraw from DNA repair to favour ATP production from pyruvate to meet the energy requirement of the neuron under stress." This is evidence that this poison is creating problem with the formation of ATP and induce the oxidative stress level up. It also causing the concentration gradient of protein not to be able to carry the hydrogen ion to final enzymes of electron transport chain. Cyanide poison is not the only poison that affect the cell metabolism. Carbon monoxide also affect the cell
