#SCPH01 Biochemistry
  1. Dietary restriction reduces mTORC1 activity,
  2. Mice with reduced mTORC1 levels had longer lives, better protection against age-related cognitive dysfunction
  3. Reducing mTORC1 decreases the amount of autophagy,
  4. Increases removal and replacement of damaged organelles and senescent cells.

There are at least three different types of companion cells in the minor veins of mature, exporting leaves. Which of the following statements about these companion cells is CORRECT?

 a.) transfer cells are transport sugars enter the apoplast during the movement of sugars from mesophyll cells to sieve elements. Transfer cells transport sugars from the apoplast to the symplast of the sieve elements and companion cells in the source.

 b.) the numerous mitochondria in companion cells may supply energy as ATP to the sieve elements

 c.) Ordinary companion cells can function in either symplastic or apoplastic short-distance transport in source leaves, depending in part on plasmodesmatal frequencies

 d.) Intermediary cells, by contrast, function in symplastic transport of sugars from mesophyll cells to sieve elements
