A) \[M{{g}^{2+}}\]
B) \[N{{a}^{+}}\]
C) \[F{{e}^{2+}}\]
D) \[{{K}^{+}}\]
Correct Answer: D
Solution :
Active \[{{K}^{+}}\] transport theory proposed by Fujino explains that when leaf is exposed to light, malic acid appears in guard cells. This malic acid dissociates into malate and \[{{H}^{+}}\] ions which results in efflux of \[{{H}^{+}}\] ions and influx of \[{{K}^{+}}\] ions. In dark reverse happen. \[M{{g}^{2+}}\]is involved in chlorophyll formation, growth, metabolism and nodule formation in legumes. \[F{{e}^{2+}}\] is involved in development of chloroplasts, chlorophyll and other pigment, protein synthesis.You need to login to perform this action.
