Question

Based on these results:

Herbicide Chlorophyll Absorption H-1 Normal G3P Production Oxygen Production Nurmal NADPH Production ATP Synthase Activity Normal Decrease H-2 Decrease Decrease Decrease Decrease Decrease H-3 Normal Decrease Decrease Decrease Decrease H-4 Normal Normal Normal Normal Decrease H-5 Normal Normal Increase Decrease Decrease

I need this:

Answer 1

Answer-

1.H-1=Binds to a protein causing it to strip electrons from water and generate superoxide radicals

Explanation- this herbicide binds to protein causing it to strip electrons from water so that only NADPH and G3P decreases other value remain normal. Due to decreased NADPH the G3P decreases. It doesn't affect proton pump so that ATP production is normal.

2.H-2= Binds to chlorophyll and shifts the absorption into the infrared range

Explanation- this herbicide binds to chlorophyll and shifts the absorption into infrared range so that chlorophyll cannot convert light energy into chemical energy and all given values decreases as first step of photosynthesis cannot occur.

3.H-3=Takes electrons from electron transport chain

Explanation- this herbicide takes electrons from electron transport chain so that chlorophyll absorption is normal but O2, NADPH, ATP and G3P decreases as electron transport chain cannot occur.

4.H-4= inactivates the enzyme that produces G3P , preventing sugars from being built

Explanation- this herbicide inactivate enzyme that produces G3P so that only G3P concentration decreases remain all values are normal.

5.H-5=Disrupts proton flow and decreases ATP synthesis

Explanation- this herbicide disrupts proton flow so that proton motive force is not generated across mitochondrial membrane and results in decreased ATP synthesis. NADPH concentration increases as protons are not transported into intermitochondrial membrane space and NAD remain in reduced form. As ATP is not synthesized G3P also cannot be synthesized.
