Of the total amount of glucose energy consumed by the body each day, about what percentage is used by the brain and nerve cells?
Alexeev081 [22]

Of the total amount of glucose energy consumed by the body each day, about 20% is used by the brain and nerve cells.

The brain constitutes about 2% of the total body but it is one of the main consumers of energy derived from glucose.

The energy provided by glucose is used for the proper functioning of the brain. It generates ATP which is an energy source that is responsible for r neuronal and non-neuronal cellular maintenance and generates neurotransmitters.

Thus glucose-derived energy is critical for the health of the brain. Lack of energy can cause several brain diseases.

Which enzymes are secreted only by the pancreas?
a_sh-v [17]

Nucleases are the enzymes that are unique to the pancreas. These are enzymes which break down nucleic acids DNA and RNA into nucleotides. When these nucleotides reach the ileum, they are further degraded or digested into sugars, bases and phosphates. These nucleases are known as DNAase and RNAase

Other pancreatic enzymes such as amylase and protease are also produced by other digestive organs such as the salivary glands and the small intestine respectively. However no other digestive organ has been known to produce nucleases apart from the pancreas.

Nucleases are of two  main types, namely exonucleases which cut off the end of a nucleotide and endonucleases which will cut out certain nucleotide sequences right in the middle of a nucleic acid.
