final exam review part 3

TRUE or FALSE: In photosynthesis, the electron transport chain extracts electrons from light and transfers them to NADP.

• True

• False

Regarding light-harvesting complexes in plant chloroplasts, which of the following is FALSE?

• They contain chlorophyll and other pigments.

• They are found in both photosystem I and photosystem II.

• They can protect the cell by preventing the generation of reactive oxygen species.

• They can carry out charge separation.

• They do not contain special pair chlorophyll.

What photosystem is on the left ?

• Photosystem I

• Photosystem II

Answer explanation

photosystem I requires sunlight, whereas photosystem II is a dark reaction. plants and algae. that the reactions of photosystem II occur in the Calvin cycle, whereas the reactions of photosystem I occur outside of the Calvin cycle

What photosystem is on the right ?

• Photosystem I

• Photosystem II

Answer explanation

photosystem I requires sunlight, whereas photosystem II is a dark reaction. plants and algae. that the reactions of photosystem II occur in the Calvin cycle, whereas the reactions of photosystem I occur outside of the Calvin cycle

This is the polypeptide sequence for a protein translated at the rough ER. The red and yellow areas are the “start-transfer” and “stop-transfer” sequences, respectively.

folded proteins (and RNA) move between the cytoplasm and nucleus via nuclear pore complexes

• Gated transport

• Transport across membranes

• Vesicular transport

• Engulfment

Answer explanation

protein translocators transport unfolded proteins (exception peroxisomes) across a membrane (or within) that is topologically distinct

• Gated transport

• Transport across membranes

• Vesicular transport

• Engulfment

Answer explanation

membrane enclosed transport intermediates (vesicles) move proteins between topically equivalent cellular

• Gated transport

• Transport across membranes

• Vesicular transport

• Engulfment

Answer explanation

autophagy, wrapping of membranes around portions of cytoplasm

• Gated transport

• Transport across membranes

• Vesicular transport

• Engulfment
