4.5 Energy and Metabolism – Human Biology

Molecular energy stored in the bonds of complex molecules is released in catabolic pathways and harvested in such a way that it can be used to produce ATP. Other energy-storing molecules, such as fats, are also broken down through similar catabolic reactions to release energy and make ATP (Figure 4).

ATP

These ATP molecules can be recycled after every reaction. ATP molecule provides energy for both the exergonic and endergonic processes.

6.3: ATP in Living Systems

All living things require energy to function. While different organisms acquire this energy in different ways, they store (and use it) in the same way. In this section, we''ll learn about ATP—the energy of life. ATP is how cells store energy. These storage molecules are produced in the mitochondria, tiny organelles found in eukaryotic cells

ATP in Living Systems | Biology for Majors I

When ATP is broken down, usually by the removal of its terminal phosphate group, energy is released. The energy is used to do work by the cell, usually by the released phosphate binding to another molecule, activating it. For example, in the mechanical work of muscle contraction, ATP supplies the energy to move the contractile muscle proteins.

Adenosine triphosphate (ATP) is a nucleoside triphosphate that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the "molecular unit of currency" for intracellular energy transfer.

ATP couples exergonic and endergonic reactions

The formation and hydrolysis of ATP constitute what might be called an "energ y-coupling cycle," in which ADP picks up energy from exergonic reactions to become ATP, which then donates energy to endergonic reactions. ATP is the common component of these reactions and is the agent of coupling, as illustrated in Figure 8.6.

Stage 2 – Energy release. The smaller molecules or the monomers are the absorbable form and are taken up by cells and are further converted to smaller molecules like, the acetyl-coenzyme A (acetyl-CoA), and releasing energy in the process.. Stage 3 – Energy Stored. Finally, the acetyl group of the CoA is oxidized to water and carbon dioxide in the citric acid

ATP: Adenosine triphosphate (video) | Khan Academy

ATP, or Adenosine Triphosphate, is the energy currency in biological systems. It''s made up of adenosine and three phosphate groups. Energy is stored when ATP is formed and released when it''s broken down into ADP (Adenosine Diphosphate) and a phosphate group. This energy release powers various biological processes.

ATP/ADP

ATP is often used for energy transfer in the cell. ATP synthase produces ATP from ADP or AMP + P i. ATP has many uses. It is used as a coenzyme, in glycolysis, for example. ATP is also found in nucleic acids in the processes of DNA replication and transcription. In a neutral solution, ATP has negatively charged groups that allow it to chelate
