The glyceraldehyde3phosphate dehyrogenase reaction is exergo

The glyceraldehyde-3-phosphate dehyrogenase reaction is exergonic and forms the first “high energy” intermediate in Stage I of glycolysis. True or False

It has been demonstrated that triose phosphate isomerase has a reaction rate that is diffusion controlled and is therefore an example of an enzyme that has reached catalytic perfection.True or False

Metabolic pathways are a series of unrelated enzymatic reactions that produce specific products. True or False

Solution

1). In this reaction aldehyde is converted into a carboxylic acid and NAD+ is simultaneously reduced endergonically to NADH.

So false

2). Since the rate of catalysis of such enzymes is set by the diffusion-controlled reaction, so it is an Diffusion limited enzyme.

Hence it is true.

3). Metabolic pathways are interconnected sequence of enzymatic reactions.

Hence it is false.
