Microvilli are filamentous structures on the surface of intestinal cells. Their formation depends on microfilaments. What would happen to intestinal cells when microfilaments’ formation is blocked by cytochalasin, a chemical that inhibits actin polymerization? Surface area decreases; cell volume decreases; efficiency of nutrient uptake increases. Surface area does not change; cell volume decreases; efficiency of nutrient uptake increases. Surface area decreases; cell volume decreases; efficiency of nutrient uptake does not change. Surface area decreases; cell volume does not change; efficiency of nutrient uptake decreases.
