"A chloroplast contains thylakoid stacks ,called stroma, that are surrounded by fluid-filled grana." which words do you flip?
Exchange the positions of "stroma" and "grana"
During the light-dependent reactions of photosynthesis, which event must occur for ATP synthase to function properly?
Hydrogen ions must pass through a channel within ATP synthase
During the process of photosynthesis, a molecule of ATP breaks apart to form a molecule of ADP and a phosphate group. How is this action of ATP useful during photosynthesis?
It releases chemical energy for the cell to use during the light-independent reactions.
Both ATP and NADPH are involved in photosynthesis. What best describes their roles?
They are intermediates that carry energy from the light-dependent reactions to the light-independent reactions.
How are the closures most likely to affect photosynthesis?
They decrease the rate of photosynthesis by preventing carbon dioxide from entering the leaf.
During photosynthesis, what best describes the role of the compound with the chemical formula C6H12O6?
a product that is useful because of its high energy chemical bonds
Which is the role of the electron transport chain in the process of photosynthesis?
carrying electrons from from photosystem II, to photosystem I, to NADP+
Which property of NADP+ should Xavier cite?
its ability to accept and release high-energy electrons and a hydrogen ion
which best describes the role of light in the overall process of photosynthesis?
light provides the energy for assembling small molecules into sugars
Photosynthesis can be modeled by its overall chemical reaction. Which two substances are the products, or outputs, of this reaction?
sugars and oxygen
In a key or legend for the model, how should William describe the roles of NADPH and ATP in the light-independent reactions?
supplying the energy necessary to assemble sugar molecules
how does the diagram model the light-dependent reactions of photosynthesis?
the left half of the diagram models the lights dependent reactions, because light provides the energy for these reactions
