The energy -requiring processes of cells fall into three categories: mechanical work, chemical work, and transport work.

Question

Quizplus · Accepted Answer

These three categories encompass the primary ways cells use energy: Mechanical work includes muscle contraction and movement of chromosomes during cell division; chemical work involves endergonic reactions such as the synthesis of polymers from monomers; and transport work involves pumping substances across cell membranes against their concentration gradient.
