Transport proteins
Active transport is when a cell needs to use energy in or to let substances pass in through or out or its cell membrane or cell wall. Passive transport requires to energy at all making substances like water easy to let pass through.

The glucose transporter is a membrane bound protein that binds to glucose and mediates it's transport into or out of the cell.

Vesicular active transport
Exocytosis!! :)
Do you mean how do substances move through a cell membrane if they are too big to transport by passive transport?If so, a cell uses active transport to move large particles in and out of a cell. Active transport includes endocytosis, pinocytosis, and phagocytosis.
lysosomes
VesiclesCell walls are the small structure. This is what transports the substances.
