Brain energy requirement, metabolism and neurotransmitter turnover consume 20 % of the available oxygen and glucose in the body.

  <span>Even though, the brain is only about 2% of the body weight, it consumes about 20% of the body's energy. It is the main consumer of glucose-derived energy. When the mental strain increases, the brain's demand for energy in the form of oxygen and glucose is higher.</span>

The Brain energy requirement, metabolism and neurotransmitter turnover consume <u>20-25%</u> of the available oxygen and glucose in the body

One of the organs that are most metabolically active is the brain. With other active organs in the body such as the liver, heart, and kidneys, it consumes approximately 60% of the body’s energy needs.

<h2>Further Explanation</h2>

The primary functions of the brain are to process and transmit information through electrical signals. The brain plays a vital role in our body.

The hearts and kidneys are metabolically active than the brain but the brain takes a higher proportion of the body’s energy requirement because it is very large. It consumes about 20 to 25% of the body’s total energy need, although it accounts for just 2% of the entire body mass.

The little energy stored by the brain is glycogen. It depends mainly on the circulating glucose for fuels. The moment the glucose gain entry inside the neurons, it is metabolized by the mitochondria in different steps to form adenosine triphosphate or cellular energy.

The glucose that is consumed by the brain is used in maintaining synaptic function; it is also used to maintain the resting membrane potentials of neurons. However, the energy requirement differs in all types of neurons.
