Gel or protein particles do what during the living state?

Gel or protein particles do what during the living state?

• A. Absorb fluid
• B. Release fluid
• C. Convert to fat
• D. Solidify

Answer: (A)

Gels and protein networks in living tissue are highly hydrated and capable of binding water. They have hydrophilic groups and charged sites that attract water, so the gel forms a hydrated matrix in the cytoplasm or extracellular space. This water binding is essential for maintaining cell volume, allowing diffusion of nutrients and wastes, and giving the tissue its mechanical properties. Because of this hydration, the typical behavior is absorption of fluid rather than releasing fluid, turning into fat, or becoming solidified under normal living conditions.
