In general, which of the following is largely responsible for moving substances across the plasma membrane, communicating with other cells, and identifying the cell?

Question

Quizplus · Accepted Answer

Proteins are responsible for moving substances across the plasma membrane (such as transporter channels and pumps), communicating with other cells (such as receptors and signal transduction pathways), and identifying the cell (such as cell surface markers). Phospholipids make up the main structural component of the plasma membrane and form a barrier to the passage of most molecules. Carbohydrates are also present on the cell surface and can play a role in cell-cell recognition, but they are not the primary drivers of movement, communication, and identification. Nucleic acids are responsible for carrying genetic information and are not typically involved in plasma membrane functions. The cytoskeleton is important for maintaining cell shape and movement, but is not directly involved in plasma membrane functions.
