Water provides electrons, hydrogens, and oxygen in photosystem I. The resulting electrons in photosystem I
A. replace the electrons lost by chlorophylls. B. are added to hydrogens so they can be transported across the thylakoid membranes more easily. C. directly pass through ATP synthase enzymes to activate them in transforming ADP to ATP. D. are added back to oxygen.

The loss of water from a plant by transpiration cools the leaf. Movement of water in transpiration requires both adhesion to the conducting walls and wood fibers of the plant and cohesion of the molecules to each other
A scientist wanted to increase the rate of transpiration of a crop species to extend its range into warmer climates. The scientist substituted a nonpolar solution with an atomic mass similar to that of water for hydrating the plants. What do you expect the scientist's data will indicate from this experiment? A) The rate of transpiration will be the same for both water and the nonpolar substance. B) The rate of transpiration will be slightly lower with the nonpolar substance as the plant will not have evolved with the nonpolar compound. C) Transpiration rates will fall to zero as nonpolar compounds do not have the properties necessary for adhesion and cohesion. D) Transpiration rates will increase as nonpolar compounds undergo adhesion and cohesion with wood fibers more readily than water.
When molecules are broken apart in respiration, ____.
A. the heat produced is used to drive biological reactions B. the oxygen in the compounds that are broken apart is used as an energy source C. the energy released is channeled into molecules of ATP D. ATP is converted into ADP E. ADP is released as a waste product
