Summary
Adenosine triphosphate stores energy in its phosphate bonds and acts as the universal energy currency of cells.
In depth
ATP is adenine, ribose and three phosphate groups. Hydrolysis to ADP and Pi releases energy because the phosphates repel each other and the products are stabilised. ATP is not stored long-term; a person turns over about their body weight of ATP daily.
It powers muscle contraction, active transport, biosynthesis and signalling, usually by phosphorylating a target and changing its shape.
Frequently asked questions
What is ATP Structure and Function?
Adenosine triphosphate stores energy in its phosphate bonds and acts as the universal energy currency of cells.
Which area of biology covers ATP Structure and Function, and how advanced is it?
ATP Structure and Function is one of the 51 topics in Biomolecules & Biochemistry. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Proteins, Denaturation, Tertiary Structure.
Can you give an example of ATP Structure and Function?
Myosin uses ATP to detach from actin and re-cock its head.
What should I learn before ATP Structure and Function?
Work through the Beginner topics in Biomolecules & Biochemistry first, such as Water Properties, Carbon Chemistry, Carbohydrates, then return to ATP Structure and Function. Advanced topics assume the Intermediate vocabulary.
What topics are related to ATP Structure and Function?
The closest topics to ATP Structure and Function are Proteins, Denaturation, Tertiary Structure, Nucleotides. Comparing them side by side is a good way to see how the ideas connect.
How can I check that I understand ATP Structure and Function?
Read the summary and the in-depth section, then use the quick check on the interactive lesson for ATP Structure and Function. To practise the whole of Biomolecules & Biochemistry, use the Biomolecules & Biochemistry quiz.
How is ATP Structure and Function different from Proteins?
ATP Structure and Function: Adenosine triphosphate stores energy in its phosphate bonds and acts as the universal energy currency of cells. Proteins: Polymers of amino acids that act as enzymes, structural parts, transporters, hormones and antibodies. Read both side by side and note what each one explains.
How should I study ATP Structure and Function step by step?
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Proteins and explain the difference aloud. Finally, take the Biomolecules & Biochemistry quiz and come back to this page for any question you miss.
