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 0, which is favorable. Although ATP is the main energy currency, other molecules can fulfill this role and take part in coupled reactions. Determine whether each of the phrases or examples describes a thioester, reduced cofactor, or phosphorylated compound:1) Acetyl-CoA2) Ubiquinol3) Phosphocreatine4) The Sulfur-Carbon bond is hydrolyzed5) These compounds yield H2PO4- upon hydrolysis6) These compounds accept e- during the oxidation of substrates and energy is released when they are oxidized.

Answer 1

Answer: Please see answer below

Step-by-step explanation:

The appropriate classification of the given phrases is given below as

--Reduced cofactors: Ubiquinol; these compounds accepts electron during oxidation of substrate and energy is released when they are oxidized.

--Thioester: Sulfur -Carbon bond is hydrolysed; acetyl CoA.

-Phosphorylated compounds: These compounds yield H2PO4 upon hydrolysis; phosphocreatine.

-----Reduced co factors are formed when the co enzyme Q Eg ubiquinone accept electrons and hydrogen, to form Ubiquinol which stores free energy from the oxidation of substrates.

-----Thioesters, acylating agents are the product of esterification from the combinatrion of a carboxylic acid and a thiol. here, the Sulfur -Carbon bond is usually hydrolysed. eg is acetyl-CoA

Phosphorylated compounds are formed when there isa chemical addition of a phosphoryl group (PO3-) to an organic molecule which yield H2PO4 upon hydrolysis eg is phosphocreatine.
