Question

During opening of stomata, influx of K+ ions into the guard cells is accompanied with efflux of (A) Na+ (B) K+ (C) Cl- (D) H+

Tardigrade Admin · Accepted Answer

According to active K+ ion transport theory, during day time, CO2 concentration decreases due to it being used up in photosynthesis. Malic acid is formed in guard cells which dissociates into malate ions and H+. K+ ions exchange with H+ ions from cytoplasm of guard cells.

Q. During opening of stomata, influx of $K^{+}$ ions into the guard cells is accompanied with efflux of

$N a^{+}$

$K^{+}$

$C l^{-}$

$H^{+}$

According to active $K^{+}$ ion transport theory, during day time, $C O_{2}$ concentration decreases due to it being used up in photosynthesis. Malic acid is formed in guard cells which dissociates into malate ions and $H^{+}$ . $K^{+}$ ions exchange with $H^{+}$ ions from cytoplasm of guard cells.

Q. During opening of stomata, influx of K+ ions into the guard cells is accompanied with efflux of

Na+

K+

Cl−

H+
