What is ATP and what is its role in powering life on Earth?
What is ATP and what is its role in powering life on Earth?
ATP is Adenosine Triphosphate, a molecule that powers all life on Earth. It is required for essential activities such as pumping ions across membranes and separating DNA strands.
Describe the structure of the ATP molecule.
Describe the structure of the ATP molecule.
The ATP molecule is made up of three main structures: an adenine nuclear base, a ribose sugar, and 3 phosphates.
How is energy released from ATP?
How is energy released from ATP?
Energy is released from ATP when the bond holding the end phosphate group is broken, converting ATP to ADP through a hydrolysis reaction.
