A scientist wanted to create a weed killer that would specifically target the weeds that grew under his apple orchard. There are a number of areas he could target that would efficiently kill plants including:

i. mitochondria

ii. plasma membrane

iii. rubisco

iv. cytochrome b6f complex

v. nuclear membrane

vi. cell wall

Which of the above areas would target the weeds, but not hurt the invertebrate animals that live in the soil?

In the following statement, fill in the blanks using one of the terms in the following list (do not include the comma). Terms that are not on the list will not be accepted.

NOTE: not all terms are required and some might be used more than once.  Spelling must be identical to that shown in the list and no punctuation marks should be included.

ATP, ATP synthase, the electron transport chain, electrons, glycolysis, photons, photosystem I, photosystem II, plastoquinone, the proton transport chain, protons

The scientist instead decided to target the binding site of ferredoxin to . This will directly disrupt by blocking movement of .

A potential issue with this weed killer could be:
