Chemical work, mechanical work, and transport work.
Chemical: An example would be the ATP building large molecules such as proteins for the cell (s)
Mechanical: An example of this would be the contraction of your muscle (s). The reason for this is because In your muscle cells, ATP transfers phosphate groups to certain proteins which allows them to then change shape starting a chain of events leading to your muscles contracting
Transport: An example would be transport work pumping solutes into a cell membrane.
There are three main types of cellular work: chemical, mechanical, and transport. For example, ATP can be used to provide the mechanical work that powers DNA helicase to separate double-stranded DNA into single- stranded DNA during DNA replication.
