It ensures the permeability of the membrane barrier. | Protein molecules within the cells |
Medium or forms of transport in the cell. | Pores or Protein Carriers |
Pores or Protein Carriers of a cell membrane are regulated and selective but it is highly permeable to? | Hydrophobic molecules such as GASES |
Cells being highly permeable to hydrophobic molecules such as Oxygen & CO2, it is also exposed to poisonous substances such as? | Carbon Monoxide & Organic Solvents |
Besides from Pores & Carriers, cells have other proteins namely? | Receptors & Enzymes |
Receives signals from the external environment and convey the information to the interior of the cell (signal transduction).? | Receptors |
It metabolizes extracellular substrates. | Enzymes |
They play an important role in regulating the internal environment, e.g., water content, osmolality,ion concentrations, pH, O2 & CO2 pressure. | Kidney & Lungs |
It processes signals from peripheral sensors (single sensory cells or sensory organs), activates outwardly directed effectors (e.g., skeletal muscles), and influences the endocrine glands. | Central Nervous System |
It is responsible for providing constant environmental conditions of the cell? | Extracellular Fluids |
A process by which physiologic self-regulatory mechanisms maintain steady states in the body through coordinated physiological activity? | Homeostasis |
The exchange of materials between blood and ___________ spaces creates a stable environment for the cells. | Intercellular spaces |
It processes signals from peripheral sensors (single sensory cells or sensory organs), activates outwardly directed effectors (e.g., skeletalmuscles), and influences the endocrine glands.? | Central Nervous System |
