"I Sprint 2:11 PM Done 6 of 6 7. The cytoskeleton provides support, structure, mobility, and organization, and it forms tracks to direct organelle and vesicle transport. Which of the cytoskeletal elemerts listed below is the thickest? a) : actn filaments intermediate filaments (d) (C) none of the above (all the same thickness) 8. Structurally, the plasma membrane A) contains some imbedded proteins B) is composed of a bilayer of lipids. C) contains some carbohydrate molecules contains some small holes, or pores all of the above 9. Erzymes A) are lipids B) function as biological catalysts C) raise the activation energy for a reaction D) are carbohydrates E)all of e above 10. Synthesis of most ATP takes place in the A) ribosomes B) rough ER C) smooth ER 4 ]Explanation / Answer
7. B) micro tubules
The thickness of the micro tubules are 25nm whereas, the actin filaments are 8nm.
8. E) all of the above.
The transmembrane proteins help in transport of molecules.
9. B) functiOn as biological catalysts
Enzymes are proteinaceous in nature and lower the activation energy of a reaction.
10. E) Mitochondria
ATP synthesis in the mitochondria occurs in the ATP synthase which are located in the inner most Mitochondrial membranes, as well as the mitochondrial matrix.
