Question

Adenosine triphosphate (ATP) is the main \"energy currency\" used in cells. ATP hydrolysis is coupled with unfavorable reactions, making the net change in energy for the set of reactions less than zero (favorable). Although ATP is the main energy currency, other molecules, such as acetyl-CoA can fulfill this role and take part in coupled reactions. Which of the following groups are present in acetyl-CoA? Select five groups.

Answer 1

Concepts and reason

Acetyl-CoA is a molecule present in protein, which participates in many biochemical reactions. The main function of this molecule is to produce energy by oxidizing the acetyl group to the citric acid.

Fundamentals

• Amido group

It is a part of the primary amine, the ${\rm{ - N}}{{\rm{H}}_{\rm{2}}}$

• Phosphoryl: It has a chemical formula ${\rm{PO}}_{\rm{3}}^{{\rm{2 - }}}$

$--=0 $

• Thioester

• Phosphoanhydride

• Imidazole like

Groups that are not present in acetyl CoA are as follows:

Carboxyl, aldehyde, and catechol

Consider the structure

The groups present in the above structure are as follows:

Amido group

Phosphoryl

Thioester

Phosphoanhydride

Imidazole like
