The Role of Proteins in the Cell
This text uses a variety of images to illustrate many dynamic functions of proteins, including catalysis, transport, defense, signaling, and movement. It focuses on specific examples for each function, including enzyme catalysis, hemoglobin’s role in oxygen transport, antibodies used in immune defense, receptors used for cell signaling, and proteins involved in muscle movement.
