AGHS - CP Bio - Light Dependent Reaction Practice - Casey Rurode | Biblioteka

Use what you know about the light dependent reactions of photosynthesis to answer the questions below.

SECTION 1

Explain the relationship between the terms given below:

1

granum & stroma

1

chlorophyll, carotenoids

1

ATP synthase, ATP

SECTION 2

Select the best answer for each question.

1

In the light dependent reactions of photosynthesis, electrons get energized and passed through a series of proteins. The process of passing electrons through these proteins is call a/an

thing of beauty

electron transport chain

bio-magic

1

What statement about chlorophyll is correct?

Chlorophyll absorbs mostly green light.

Chlorophyll absorbs mostly red and blue light.

Chlorophyll is responsible for the red and orange colors seen in autumn leaves.

Chlorophyll means the exact same thing as the term chloroplast.

1

The photosystems that energize electrons and the items that transfer electrons through the light dependent reactions are located in the ___. Hint: use the notes diagram from class to help you!

stroma

thylakoid membrane

inner membrane of the chloroplast

outer membrane of the chloroplast

1

Both photosystem I and photosystem II ____.

contain pigments to absorb light energy

energize electrons so that NADPH can be made

are part of the Calvin Cycle AKA the light independent reactions

energize electrons so that ATP can be made

1

Water and sunlight are essential to the process of the light dependent reactions. Water is directly used in the light reactions of photosynthesis to ____.

to add a phosphate to ADP

absorb light energy

provide electrons that move through the light dependent reactions

make sugar

1

At the end of the light dependent reactions what two energy molecules have been created and will be used as reactants in the next phase of photosynthesis?

ATP & glucose

glucose & NADPH

ATP & sunlight

ATP & NADPH
