Final answer:
Rho is a protein from the Rho family of small GTP-binding proteins that plays a crucial role in regulating cell functions. Active Rho is bound to GTP and can interact with other proteins, while inactive Rho is bound to GDP and is unable to interact.
Step-by-step explanation:
Rho is a protein that belongs to the family of GTPases, specifically the Rho family of small GTP-binding proteins. These proteins play a crucial role in regulating cell shape, movement, and signaling pathways. One main difference between active and inactive Rho is the presence or absence of a bound molecule called GTP (guanosine triphosphate).
'''Active Rho''' refers to the form of Rho that is bound to GTP. In this state, Rho is active and can interact with other proteins to carry out its functions. It is involved in processes such as cell migration, cytoskeletal organization, and gene expression.
'''Inactive Rho''' refers to the form of Rho that is bound to GDP (guanosine diphosphate). In this state, Rho is inactive and unable to interact with other proteins. Activation of Rho involves the exchange of GDP for GTP, which leads to a conformational change and enables Rho to perform its cellular functions.
