Vedclass · Answer

(C) The brain controls the functions of our body organs and provides cognitive abilities such as learning,reasoning,and memory.For such activities,the brain requires a large and constant energy supply.The brain accounts for $20\%$ of the body's total $O_2$ consumption and $5\%$ of its total blood glucose consumption.If the brain is deprived of $O_2$ for just $5$ minutes,it sustains permanent damage.If the brain is deprived of glucose,it leads to mental confusion.Therefore,statements $I$ and $IV$ are correct.
