Sergio039 [100]

Answer:

The fate of glucose-6-phosphate,glycolytic intermediates and pentose phosphate pathways are described below

Explanation:

Fate of Glucose -6-phosphate

Glucose-6-phosphate undergo dephosphorylation to form glucose when there is an increase demand of glucose in the body.

Glucose-6-phosphate enters into pentose phosphate pathway to synthesize ribose-5-phosphate which is used during denovo pathway of purine nucleotide biosynthesis.

Fate of glycolytic intermediates

Glyceraldehyde-3-phosphate is an important intermediate of glycolysis.The glyceraldehyde-3-phosphate act as a precursor during lipogenesis that deals with the biosynthesis of triacylglycerol.

Fate of pentose phosphate pathway intermediates

Ribose-5-phosphate and NADPH are the important intermediates of pentone phosphate pathway.

 Ribose-5-phosphate act as a substrate molecule during the denovo biosynthesis pathway of purine nucleotides.

NADPH act as a reducing agent during fatty acid biosynthesis process.

how is it possible mohave thousands of different proteins when there are only 20 different amino acids
TEA [102]
Hi there!

Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins. 

<span>In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.</span>
