If ATP hydrolysis is not coupled with cellular work, then energy released is converted to heat energy.
Most cellular work is accomplished by using adenosine triphosphate (ATP) as the primary energy source. ATP is synthesized during cellular respiration and stores energy in its phosphate bonds, which can be broken to release energy for cellular processes. The hydrolysis of ATP releases this energy, providing it to molecules to drive cellular work.
The energy from the hydrolysis of ATP may be directly coupled to endergonic processes by the transfer of the phosphate group to another molecule. A key feature in the way cells manage their energy resources to do this work is energy coupling, the use of an exergonic process to drive an endergonic one. ATP is responsible for mediating most energy coupling in cells, and in most cases it acts as the immediate source of energy that powers cellular work.
ATP releases energy when the phosphate group is cleaved off in a process called hydrolysis. This generates ADP (adenosine diphosphate) and inorganic phosphate, releasing energy stored in the chemical bonds for cellular work.
G-protein coupled receptors (GPCRs) work by binding to specific molecules outside the cell, which triggers a series of events inside the cell. When a molecule binds to the GPCR, it activates a G-protein inside the cell, which then triggers a cascade of signaling pathways that ultimately lead to a cellular response. This allows cells to respond to external signals and regulate various processes within the body.
ATP powers cellular work by being a source of energy that drives various processes within the cell. When ATP is broken down into ADP and inorganic phosphate, energy is released that can be used to fuel cellular activities like muscle contraction, protein synthesis, and active transport of molecules across cell membranes. This process is known as ATP hydrolysis.

The hydrolysis of ATP releases energy because the phosphate bonds in ATP are high-energy bonds. Breaking these bonds through hydrolysis releases energy that can be used by cells for various biological processes. The energy released is used to drive cellular activities and perform work within the cell.

When ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate), a phosphate group is removed via hydrolysis, releasing energy that can be used by the cell for various processes. This conversion is a critical step in cellular metabolism to provide energy for cellular functions.

ATP
The cell is able to harness the energy released during ATP hydrolysis more efficiently through coupled reactions, channels, and enzymes to perform cellular work. This results in less energy being dissipated as heat compared to the test tube environment. In a living cell, energy is often used for metabolic processes rather than being lost as heat, making it more energy-efficient in utilizing ATP.
Glucose is the most important cellular fuel, but none of the chemical energy contained in its bonds is used directly to power cellular work. Energy released during glucose catabolism is coupled to the synthesis of ATP. Cells tap ATP's bond energy during coupled reactions by using enzymes to transfer the terminal phosphate groups from ATP to other compounds. These newly phosphorylated molecules are said to be "primed" and temporarily become more energetic. In the process of doing their work, they lose the phosphate group. As a result, cells are protected by excessive energy release that might be damaging, and energy squandering is kept to a minimum.
