Answer:
A. hydrolysis reaction.
Step-by-step explanation:
Chemical Reactions.
First, let's review each concept of the group of answer choices:
- hydrolysis: is a reaction in which the net reaction is an organic compound reacting with water to give either two molar equivalents of a single product or more than one product.
- redox: is a type of chemical reaction that involves a transfer of electrons between two species.
- combustion: is a reaction in which a substance reacts with oxygen gas, releasing energy in the form of light and heat.
- neutralization: is a reaction that occurs when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water.
The problem is asking for the reaction that removes a phosphate group from ATP, so let's see the structure of ATP with one phosphate group:
What is enclosed in the red box is the phosphate group.
The reaction that removes this phosphate group represents a rupture of the structure and based on the logic of the definitions of the given concepts, the answer would be that the reaction to remove one phosphate group from ATP is A. hydrolysis reaction. This reaction looks like this:
ATP + water (H2O) -> ADP + Pi,
where ADP is the same molecule of ATP but it has two phosphate groups and Pi is the phosphate group removed.
