Photosynthesis---9.1 and 9.2

Front

What is the compound that cells use to transfer and release energy?

Back

ATP (Adenosine triphosphate) is the primary energy carrier in cells.

Front

What are the reactions that change the energy of sunlight to energy-rich carriers called?

Back

Light-dependent reactions convert sunlight energy into chemical energy.

Front

What are the reactions in photosynthesis that require light and light-absorbing pigments?

Back

Light-dependent reactions are the processes that require light and pigments.

Front

What is a light-absorbing molecule in photosynthesis?

Back

Pigments are molecules that absorb light energy, such as chlorophyll.

Front

True or False: Most cells only store enough ATP for a few seconds of activity.

Back

True, cells typically store only a small amount of ATP.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily in the blue and red wavelengths.

Front

What is the main product of the light-dependent reactions?

Back

The main products are ATP and NADPH, which are used in the Calvin cycle.

Front

What is the Calvin cycle?

Back

The Calvin cycle is a series of light-independent reactions that convert carbon dioxide into glucose.

Front

Where do light-dependent reactions occur in the chloroplast?

Back

Light-dependent reactions occur in the thylakoid membranes of chloroplasts.

Front

What is the function of the stroma in chloroplasts?

Back

The stroma is the fluid-filled space where the Calvin cycle takes place.
