Adrianne is explaining why chlorophyll is classified as a plant pigment and how it is useful in photosynthesis. Which property of chlorophyll would be most appropriate for her to cite?

chlorophyll's ability to absorb light.

chlorophyll's green color.

chlorophyll's presence in chloroplasts.

chlorophyll's reactivity with oxygen.

What BEST describes the role of light in the overall process of photosynthesis?

Light provides energy for making small molecules into sugars

Light provides energy to break sugars into small molecules

Light accepts the energy that is released by small molecules

Light accepts the energy that is released by sugars.

What BEST describes the roles of photosystem I and photosystem II in the process of photosynthesis?

They absorb sunlight and transfer the energy to electrons.

Transfer e- from a series of intermediates to form NADPH

They absorb sunlight and distribute the energy as heat.

They form ATP as hydrogen ions cross the thylakoid membrane.

Which is the role of the electron transport chain in the process of photosynthesis?

carrying e- from PS II, to PS I, and to NADP+

removing electrons from the chloroplast

adding energy to the electrons that enter photosystem I

cycling electrons between photosystem I and photosystem II

During the light-dependent reactions of photosynthesis, which event must occur for ATP synthase to function properly?

H+ ions must pass through a channel within ATP synthase

Molecular oxygen must combine with ATP synthase

ATP must release a phosphate group to become ADP

Photosystem I and photosystem II must be deactivated

Alan is developing a model of the light-independent reactions of photosynthesis, also known as the Calvin cycle. How should the model show how carbon compounds enter and exit the cycle?

enter as carbon dioxide, exit as 6-carbon molecules

enter as carbon dioxide, exit as 3-carbon molecules

enter as glucose, exit as 3-carbon molecules

enter as glucose, exit as carbon dioxide

Describe the roles of NADPH and ATP in the light-independent reactions.

supplying the energy necessary to assemble sugar molecules

providing the carbon for sugar molecules

absorbing the energy of light & transferring it to electrons
