Answer: C. Ii & III are correct
II. reduced intracellular ATP.
III. apoptosis or necrosis.
Explanation:
Cytochrome c oxidase controls the last step of food oxidation. Cytochrome c oxidase is an enzyme responsible for electron transfer in the electron transport chain (ETC), it inhibit in slowing down or stopping the ETC.
Consequently, ATP production would be gradually reduced, as the ETC is responsible for the majority of ATP production. This shows option II is correct.
The question starts by stating that cyanide is highly toxic, so this match up with the fact that a large dose would also cause cell death (apoptosis or necrosis). Therefore, option III is also accurate.
Option I: Inhibiting the ETC is consequential as it reduces oxygen demand because electrons would not flow to oxygen, the final electron acceptor.
Mitochondria also regulate cellular metabolism along with energy production and thus its role is not confined only to energy factories.
Answer:
The nervous system comprises of the brain, sensory organs and spinal cord. The nerves of the body is used to communicate with all the parts of the body.
The brain and the spinal cord is known as the control system of the body which is helps in taking decisions.
The central nervous system helps in maintaining balance of the body, processing the information and based on that response is generated.
The signals from the brain is sent to various parts of the body and from body the signals are sent to the brain for processing.
Hence, the nervous system helps in sensory, motor and integration part of the body.
