Osmotic Adjustment/ Regulation

sensing mechanism

transducing mechanism

Carbon Dioxide

Separation of opposite charges
creates a strong attraction

Facilitates cellular movement
of water

Porins

major intrinsic
proteins (MIPs) that are found in the cell membranes

membrane protein channels or
pores controlling the selective
movement of water

detect changes in specific
environmental parameters

propagates the signal generated
by the sensor and subsequently
elicits a specific cellular response

sensor protein

response regulator
