Answer:

The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule.(Ans. B)

Explanation:

ATP is a complex chemical which provides energy for many processes in living cells.

ATP hydrolysis is known as the catabolic reaction. High energy phophoanhydride bond present in adenosine triphosphate where chemical energy has been stored and released by splitting of these bonds. (high energy phophoanhydride bonds)

ATP is formed by the combination of ADP and phosphate group. The energy is released by the hydrolysis of ATP is used for the cellular works. This energy is mainly used by the coupling endergonic reactions with exergonic reaction of ATP hydrolysis.

Which substance is completely consumed in a chemical reaction?
Rudiy27

Answer:

Limiting Reactant

Explanation:

Observe the answer choices:

A) Limiting Reactant; a limiting reactant, as can be seen from the name, is the reactant that <em>limits</em> the amount of products can be made. This is because the reaction can only go on if there is enough reactants. However, the limiting reactant is the one that will run out first, so it's going to be completely consumed.

B) Reactant; a reactant is the thing that is being consumed in a reaction. However, reactants aren't always completely consumed. There's something called an excess reactant, which is essentially the opposite of a limiting reactant in that when the limiting reactant is used up, there's still some excess reactant left - because it's in <em>excess</em> / there's more than enough remaining. So, this is incorrect.

C) Products are the ones that are created during the chemical reaction, so they aren't consumed in any way. Thus, this is wrong.

The answer is limiting reactant.

Hope this helps!
