To do their work, proteins … WebAs mentioned above, a protein’s shape is critical to its function. For example, an enzyme can bind to a specific substrate at an active site. If this active site is altered because of local changes or changes in overall protein structure, the enzyme may be …
WebOct 7, 2024 · Structural proteins help to give the cell support and shape. Cell membrane receptor proteins help cells communicate with their external environment through the use of hormones, neurotransmitters, and other signaling molecules. Transport proteins, such as globular proteins, transport molecules across cell membranes through facilitated diffusion. WebThe three-dimensional shape of a protein determines its function. This is because proteins form attachments and interact with many other molecules and structures inside organisms. The...
