When light strikes chlorophyll of photosystem II, a molecule loses electrons to an electron
transport chain. What molecule donates electrons to chlorophyll so that chlorophyll doesn't run
out of electrons? NAOPH water oxygen light Water molecules stick to other water molecules
because ... water molecules are neutral, and neutral molecules are attracted to each other
hydrogen bonds form between the hydrogen atoms of one water molecule and the oxygen atoms
of other water molecules covalent bonds form between the hydrogen atoms of one water
molecule and the oxygen atoms of other water molecules the hydrogen atoms of adjacent water
molecules are attracted to one another What is the fundamental difference between covalent and
ionic bonding? In a covalent bond, the partners have identical electronegativity, in an ionic
bond, one them is more electronegative. In a covalent bond, the atoms Share a pair of electrons;
in an ionic bond, one atom an electron from the other In covalent bonding, both partners end up
with filled outer electron shells in ionic one partner does and the other does not Covalent bonds
form between atoms of the same element; ionic bonds, between different element What major
event occurs during the final phase of the Calvin Cycle (the regeneration Sunlight is used make
CO_2 CO_2 are used to make sugar molecules A TP is used to make chlorophyll ATP is used
to make RuBP molecules The following diagram depicts the energy changes associated with
what type
Solution
6. Water. Light dependent hydrolysis of one molecule of water releases 2 electrones that are
shuttled into the photosynthesis II.
7. b. water molecules form intra-molecular hydrogen bonding (between oxygen of one molecule
to hydrogen of other moleccule) because of which they attach to each other.
8. b. Covalent bonds share a pair of electrones whereas in an ionic bond there is a transfer of
electrones from one electronic species to another.
9. d. ATP is used to regenerate RuBP. 3 ATP molecules are used to regenerate RuBP from
glyceraldehyde-3-phosphate.
