question 8 options:

large molecules such as hormones

positive and negative ions

small molecules such as carbon dioxide

water and glycerol

"Large molecules such as hormones" types of materials are expelled from cells during exocytosis.

Option A

Explanation:

The mechanism whereby a cell transfers secretory products to the plasma membrane via the cytoplasm is termed as "exocytosis" while material passage into the cell is known as "endocytosis". Exocytosis is need for removing waste material from cell.

In exocytosis, mechanism huge quantity of molecules which means bulk transport is performed.Responsible for secretion of digestive enzymes and hormones. In this process, membranes-bound secretory vesicle pass to the cell membranes while their material like water-soluble molecule get secreted in the extracellular atmosphere.
