ATP Flashcards
Students learn about the structure and function of ATP, the stages of cellular respiration, and the role of ATP in cellular processes. They also conduct practical experiments to demonstrate cellular respiration and the production of ATP, gaining hands-on experience in cellular energy metabolism.
What is ATP
single molecule of ATP is nucleotide derivative
-adenosine tri phosphate
what is the function of ATP
immediate source of energy in biological processes
what make up the ATP
-adenine- nitrogen containing base
-ribose- pentose sugar
-three inorganic phosphate group
how is ATP hydrolased
-atp is hydrolased into ADP + Pi
-catalysed by the enzyme ATP hydrolase
how is ATP resynthesised
during respiration ATP is resynthesised by the condensation of ADP + Pi which is catalysed by the enzyme ATP synthase
describe how energy is released in the hydrolysis of ATP
-breaking one of the bonds between the inorganic phosphate group in a hydrolysis reaction releases small amounts of energy
why is ATP an immediate source of energy
only one bond has to be hydrolysed to release energy
describe the properties of ATP
1) releases small amounts of energy- less energy is wasted
2) small + soluble- easily transported around the cell
3) only one bond is hydrolysed to release energy- immediate source of energy
4)ATP cannot pass out of the cell- cell has an immediate supply of energy
