ATP - uses of ATP With Test Questions
And Answers

What are the 6 main uses of ATP? - Answer - 1. Metabolic processes

2. Movement

3. Active transport

4. Endocytosis and exocytosis

5. Cell division

6. Activation of molecules



Metabolic processes - Answer - ATp provides energy needed to build up polymers from smaller
monomers:

1. protein synthesis from amino acids

2. Polysaccharide synthesis from monosacharides

3. DNA/RNa synthesis from nucleotides



Movement - Answer - ATP provides the energy for muscle contraction, enabling filaments of the muscle
to slide past one another and therefore shorten the overall length of the muscle fibre.



Active Transport - Answer - ATp provides the energy to change the shape of carrier proteins in the
plasma membrane, allowing ions and molecules to be moves against their concentration gradient.



Edndocytosis/ Exocytosis - Answer - ATP provides the energy for the movement of vesicles either into
or out of the cell



Cell Division - Answer - ATP provides the energy for the contraction of spindle fibres separating
chromosomes during Anaphase of mitosis and meiosis
