| | to allow binding to the ribosome. 3. The cisternal maturation model is just one model that describes how objects might move through the Golgi. Some of the statements below describing the cisternal maturation model are correct and some are incorrect. Select all the incorrect descriptions. | | There's no need for retrograde movement | | | Vesicles bud off from the Trans Golgi Network toward the plasma membrane | | | Vesicular tubules move materials from the cis to medial Golgi networks. | | | There are no vesicles moving in the anterograde direction 4. Select all statements that are correct concerning electron transport and ATP synthesis during photosynthesis in chloroplasts. | | Each photosystem (I and II) pump protons. | | | Protons are pumped into the lumen of the thylakoid. | | | The bulb of the synthase projects into the stroma | | | Photosystem I is reduced directly by Photosystem II 5. Select all that are true about ATP synthesis with an FoF1 synthase complex. | | Each ADP+Pi is transferred from one beta subunit in Open conformation to a second beta subunit in Loose conformation and finally to the 3rd beta subunit in the T conformation | | | As the gamma subunit rotates to each beta subunit, it forces them to the open state. | | | As the gamma subunit rotates to a particular beta subunit, the unit before it changes conformation to Tight and the one ahead of it changes to Loose | | | As the gamma subunit rotates to a particular beta subunit, the unit before it changes conformation to Loose and the one ahead of it changes to Tight | | | All 3 beta subunits are always in a different conformation (open, loose, or tight) 6. The number of ATPs per NADH generated by the electron transport system is higher than the number generated per FADH2 because __________. | | electrons from FADH2 are not oxidized all the way to water | | | NADH is converted to NAD+, which increases the charge gradient for ATP synthesis | | | FADH2 has a lower (less negative) redox potential than NADH does | | | FADH2 has a higher (more negative) redox potential than NADH does | | | | |
