Energy and ATP this A-Level Biology section of Revision Science explains the need for energy and the uses of photosynthesis and respiration.
ATP is formed during respiration, when the energy released from ingested glucose powers the addition of a inorganic phosphate molecule to a molecule of adenosine diphosphate (ADP), the enzyme ATP synthase is responsible for this. Related Biology A Level answers.

Resting muscles store energy from ATP in the myosin heads while they wait for another contraction. Home › Biology Revision › AQA A-Level AQA A-Level Biology Revision For each of the papers below, there are revision notes, summary sheets, questions from past exam papers separated by topic and other worksheets. ATP is never stored. Glucose and fatty acids are short-term energy stores, while glycogen, starch and triglycerides are long-term stores. When an ATP molecule is hydrolysed, losing one of its phosphate groups, some of this energy is released and can be used by the cell.
When a chlorophyll molecule absorbs light energy, it excites the electrons, raising them to higher energy level.

The hydrolysis of ATP can be coupled to energy-requiring reactions within cells. The inorganic phosphate released during the Adenosine triphosphate is able to supply energy to cells in a manageable way. It is a nucleotide comprised of three phosphate groups, a pentose ribose sugar and an adenine nitrogenous base. A Level Biology exam questions.
