Many essential nutrients are transported into plant cells through cotransport with H*, which flows back into the
cytoplasm. Proton pumps in the cell membrane of plant cells actively pump H* into the extracellular space using
energy from ATP hydrolysis.
If a toxin that inhibits the plant proton pump is applied, which of the following would be true?
O The sodium-potassium pump would cease to operate.
O There would be more potential energy outside the cell than inside.
The electrochemical gradient across the cell membrane would be depolarized.
The cotransport of solutes against their concentration gradients would be enhanced.

This is a typical grassland food web. it is also a small picture of an important cycle on earth: the carbon cycle. describe how the carbon gets into this food web. a) bacteria and fungi, the decomposers, recycle carbon from dead organisms. b) carbon is found in the grass and is passed from one level to the next in this food web. eliminate c) all living things give off carbon dioxide as a by-product of respiration and it is released into the atmosphere. d) plants use carbon dioxide as a reactant in photosynthesis, to make usable chemical energy in the form of a sugar.
