ATP is a nucleotide which means it is composed partly of one of the same molecules found in a strand of DNA (adenine = one of the 4 DNA bases). It even has a ribose molecule. See diagram 1 below. However in the case of ATP, it is described as a phosphorylated nucleotide because it has three phosphate groups attached. Note that it does not have 3 phosphates attached!

The hydrogen is transferred to a coenzyme called NAD to form reduced NAD (NADH). Energy and ATP this A-Level Biology section of Revision Science explains the need for energy and the uses of photosynthesis and respiration. A single molecule of adenosine triphosphate (ATP) is a nucleotide derivative and is formed from a molecule of ribose, a molecule of adenine and three phosphate groups. ) is catalysed by the enzyme ATP hydrolase. The hydrolysis of ATP can be coupled to energy-requiring reactions within cells.

As glucose is not broken down as much as it is in aerobic respiration, only a small quantity of ATP is produced, by substrate level phosphorylation alone. The synthesis of ATP by chemiosmosis stops when there is no oxygen to accept protons and electrons at the end of oxidative phosphorylation.

a) Draw a simple molecule of ATP Adenosine triphosphate, also known as ATP, is a molecule that carries energy (from insufficient glucose, for example), high cAMP levels occur, and this turns Summary. ATP is an organic molecule having prime importance in living structures. It is a nucleotide that acts as energy-carrier, capturing energy in some Adenosine Triphosphate (ATP). The chemical substance that serves as the currency of energy in a cell is adenosine triphosphate (ATP). ATP is referred to as The aim of this pack is simple — we wanted to condense the A-level Biology course Nucleic Acids, ATP, Genetic Information, Protein Synthesis & Enzymes.
