Identify this molecule and outline its importance in cellular metabolism - HSC - SSCE Chemistry - Question 34 - 2010 - Paper 1

ATP is essential for numerous biochemical processes, such as:

1. Energy Transfer: It captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.
2. Biosynthesis: ATP provides the energy needed for the synthesis of macromolecules such as proteins, nucleic acids, and lipids, which are vital for cell structure and function.
3. Cellular Respiration: ATP is produced during cellular respiration, which allows cells to perform work, enabling growth and maintenance.
4. Muscle Contraction: ATP is necessary for muscle contractions, as it powers the interaction between actin and myosin filaments.

Overall, ATP is indispensable for life, supporting various metabolic activities within the cell.
