      Hi, I am having trouble answering these 2 questions. I have already searched my book.

      First, which of the following cell components is not directly involved in synthesis or secretion?
      Smooth ER, Golgi Apparatus, Rough ER, or lysosome.
      According to my book (Campbell and Reece) they all seem to be involved in those processes.

      Second, The structural filament most actively involved in movement of molecules and organelles within the cell is the:
      intermediate filament, microfilament, microtubules, or all participate equally.
      I am unsure about this one because my book implies that all participate, but it does not imply that participation is equal.

      Please help I have my midterm this week and I want to be ready. Thanks in advance!

      you are right on both of them, they are pretty vague questions..
      No 1. lysosomes, deffinetly(altough they are involved in secretion sometimes)
      No2. microtubules probably..

      no 2 is indeed microtubules.

      My answer:

      No.1 is lysosome. It is the product of synthesis or the package of the secretion, while the rest is where the synthesis takes part.

      No.2 is microtubules. The other filaments construct the microtubules so it can function.

      I’m glad everyone agrees with me 😆
      Doc, what do you mean by "other filaments construct the microtubules"? Each cytoskeletical element has it’s own important role..

      intermediate filaments are important for structural support of the cell 😉

      The tubulin construct the microtubule at the MTOC as i know
      And some MAP does effect on it and have the function of connect to other filaments
      but the "construt" …
