What does light do when it strikes the chlorophyll molecules of photosystems I and II?
Light causes glucose to be synthesized directly inside the chlorophyll molecules of the photosystems.
Light causes electrons to get excited (gain energy) and travel down the electron transport chain embedded in the thylakoid membrane.
Light causes the conversion of water into carbon dioxide, oxygen, and electrons.
Light directly causes carbon dioxide to attach to RuBP during the carbon fixation stage of the Calvin Cycle.

After light excites the electron and they leave Photosystem II to travel down the first electron transport chain, how are these electrons replaced to Photosystem II?
Oxygen is reduced and the electrons are given to the chlorophyll molecules of photosystem II.
Carbon dioxide is split, and the electrons are given to the chlorophyll molecules of photosystem II.
Hydrogen undergoes fusion, and the electrons are given to the chlorophyll molecules of photosystem II.
Water is split, and the electrons are given to the chlorophyll molecules of photosystem II.

The splitting of water at photosystem II is known as ____ and results in the production of _____.
photosynthesis: carbon dioxide, G3P, and electrons that are given to photosystem II.
photolysis: oxygen, hydrogen ions (protons), and electrons that are given to photosystem II.
the Calvin cycle: carbon dioxide, G3P, and electrons that are given to photosystem II
chemiosmosis: oxygen, hydrogen ions (protons), glucose and electrons that are given to photosystem II.

As the electrons travel from photosystem II down the first electron transport chain, their energy is used to….
form oxygen, water, NADPH, and glucose.
pump hydrogen ions into the stroma, producing a concentration gradient that will later be used by an enzyme to form ADP and phosphate.
pump hydrogen ions into the thylakoid space, producing a concentration gradient that will later be used by ATP synthase to form ATP.
create glucose directly.

MULTIPLE CHOICE QUESTION

Why do hydrogen ions flow from the thylakoid space to the stroma through ATP synthase?
They are pumped actively through the ATP synthase. This uses ATP energy and causes the production of ADP and phosphate.
They flow through the Calvin cycle and produce light.
Hydrogen ions do not actually flow from the thylakoid space to the stroma. They flow the opposite way.
They flow passively from the high to low concentration via facilitated diffusion. As they flow through ATP synthase, the enzyme spins and produces ATP.

After electrons get excited by light a second time (at photosystem I), where do they go?
They travel down a second electron transport chain and are donated to ADP, which is then converted to ATP.
They remain excited and then travel to photosystem II where they get even more excited until they spontaneously combust.
They travel down a second electron transport chain and are donated to NADP+ which becomes NADPH (an electron carrier).
They travel down a second electron transport chain and are donated to oxygen which then bonds to hydrogen ions to form water.
