Quizplus · Accepted Answer

Expansins are enzymes that are secreted by the cytoplasm and are involved in cell wall loosening. They work by disrupting the hydrogen bonds between cellulose microfibrils and other components of the cell wall, allowing for expansion and growth of the cell. Auxins may also influence cell wall loosening, but they primarily regulate cell growth and differentiation. Cellulose-digesting and starch-digesting enzymes break down components of the cell wall, but they do not necessarily contribute to overall wall loosening. Calcium ions can also play a role in cell wall loosening, but they primarily function in maintaining the integrity and strength of the cell wall.
