In addition to generating reducing power (i. e., NADPH) for biosynthesis, the pentose phosphate pathway also provides precursors for synthesis of which of the following? (Select all that apply.)

Choose one or more:A. fatty acidsB. aromatic amino acidsC. acetic acidD. nucleic acidsE. citric acid

B.aromatic amino acids.

D.nucleic acids

Explanation: Pentose phosphate pathway is a parallel biosynthetic pathway compared to the Glycolytic pathway,it produces NADPH(Nicotinamide adenine dinucleotide phosphate hydrogen) and a five carbon pentose sugar.

Aromatic amino acids (AAA), are amino acids that contain aromatic rings in their structure.

Nucleic acid is a biomolecular material that is an essential base of all protein compounds.

The correct options are B and D

AROMATIC AMINO ACIDS and NUCLEIC ACIDS.

Explanation: The pentose phosphate pathway takes place in the cytosol of the cell which is the same location glycolysis takes place. The two most important products from pentose phosphate pathway are the ribose-5-phosphate sugar used to make DNA and RNA, and the nicotinamide adenine dinucleotide phosphate (NADPH) molecules which help with building other molecules.

The pentose phosphate pathway does not consume or produce Adenosine Triphosphate (ATP) and does not require molecular oxygen.

the oldest known insects are believed to live around 400 millions ago as suggested by the fossil records.   some plants having woody stems also evolved during this time.

after the evolution of insects the first four legged species or the tetrapods evolved in shallow freshwater habitats from the intermediate species approximately 397 million years ago. the tetrapods went on conquering the land giving rise to amphibians, reptiles, mammals and birds.

the major split in tetrapods first occurred 340 million years ago branching off from amphibians.

363 million years ago when the carboniferous period began the insects started roaming on land and taking flights, following which the four limbed tetrapods adapted in the terrestrial habitat.
