1. Use the insulin release pathway from beta cells and Identify each transport process. Describe what is being transported and the mode of transportation used to move it.

2. Review the basic components of a cell signaling pathway. Assign proteins from the cellular pathway to these components.

3. Insulin release is part of long-distance reflex pathways. For example, sugar absorbed by the digestive system can stimulate insulin release, which binds to skeletal muscle to change their glucose transport. Which pathway is one that insulin release could be a part of? Choose a pathway and explain your reasoning.
