Cells can make proteins that need to be transported out of the cell and moved to another part of the body. Cells also make carbon dioxide as a waste product of cellular respiration. Proteins are large molecules; carbon dioxide is a small molecule. Which best describes how the proteins and carbon dioxide are going to exit the cell?
The proteins will be transported through endocytosis; the carbon dioxide will be transported by active transport.
The proteins will be transported through exocytosis; the carbon dioxide will diffuse through the membrane.
The proteins will be transported by active transport; the carbon dioxide will be transported by osmosis.
The proteins will be transported by facilitated diffusion; the carbon dioxide will be transported by exocytosis.
