Document Summary
Soybeans are sensitive to low iron, which results in slow growth. Atpase is active, to pump out hydrogen ions, thereby reducing ph, so iron can be released for uptake. Fro protein: reduces ferric iron to ferrous iron by transferring electron to nadh. Ferrous iron transporter is required to move fe2+ in root cortex. Plant roots can modify their environment to assist nutrient uptake. If you have a soybean plant with iron deficiency stress and yellow leaves, crop is potentially less nutritious for humans to eat, and yield is low. When they lack iron, soybeans turn yellow. To be available for uptake by a plant, a mineral must be _____. Under high ph conditions, most iron is bound to _________. Emit hydrogen ions, thereby lowering ph which helps release iron particles form soil. Help change fe3+ to fe2+ (reduction reaction) Study: cadmium accumulation in browse vegetation, alaska implications for animal health.
