Question

8. Facilitated diffusion differs from ordinary diffusion in that facilitated diffusion A. Expends no ATP 8. Moves molecules from an area of their higher concentration to their lower concentration C. The rate of molecular movement is limited by the number of available D. Never eliminates the concentration gradient E. The rate of molecular movement is not limited by the number of available carrier carrier molecules molecules 9. Crenation occurs when a blood cell is placed in a(nL solution. A. Isotonic B. Hypertonic C. Hypotonic D. Merotonic E. Homotonic 10. Components of the cytoskeleton may include all of the following, except: A. Microfilaments B. Intermediate filaments C. Basal bodies D. Microtubules E. Thick filaments 11. The process of forming mRNA is called A. Replication B. Transcription C. Translation D. Ribolation E. Auscultation

Explanation / Answer

8.Facilitated diffusion differes from ordenery diffusion in that facilitated diffusion the rate of molecular movement is limited by the number of available carrier molecules.

9.crenation occurs when a blood cell is placed n a(n) hypertonic solution(hypertonic = more concentrated than cytoplasm, crenation = shrinkage of cell)

10. components of the cytoskeleton may include all of the following except basal bodies ( because basal bodies found in flagella of cell it is protein body)

11. the process of forming mRNA is called Transcription (replication= DNA duplication, translation= protein formation from mRNA)
