Following are some facts regarding spatial separation of PSI and PSII. Which one would be INCORRECT?

#SCPH06 I Botany
  1. PSII reaction centres feed reducing equivalents into a common intermediate pool of soluble electron carriers while The PSI reaction centres remove the reducing equivalents from the common pool
  2. Most commonly, the ratio of PSII to PSI is about 1.5:1, but it can change when plants are grown in different light conditions
  3. Most measurements of the relative quantities of photosystems I and II have shown that there is an excess of photosystem II in chloroplasts
  4. Separation implies that one or more of the electron carriers that function between the photosystems diffuses from the grana region of the membrane to the stroma region, where electrons are delivered to photosystem II

Following statements are regarding to the spindle position checkpoint pathway in budding yeast.

A. During interphase and early mitosis, Cdc14 is sequestered and inactivated in the nucleolus. Inactive Tem1-GDP associates with the spindle pole body (SPB) nearest to the bud as soon as the mitotic spindle forms.

B. If chromosome segregation occurs properly, extension of the spindle microtubules inserts the daughter SPB into the bud, causing Tem1 to be activated by an unknown mechanism.

C. Tem1-GDP activates a protein kinase cascade, which then promotes the release of active Cdc14 from the nucleolus and exit from mitosis.

D. If the spindle apparatus fails to place the daughter SPB in the bud, Kin4 (cyan), an inhibitor of Tem1, is recruited from the parent cell cortex to the parent-cell-located SPB and maintains Tem1 in the GTP-bound form, and mitotic exit does not occur.
