A Student Claims That Both Freeze-Fracturing Techniques and Cell Fusion

question 56

Multiple Choice

A student claims that both freeze-fracturing techniques and cell fusion experiments provided evidence that supported the fluid mosaic model used to describe the cell membrane.Which statement best evaluates this student's claim?

• A) The claim is accurate because freeze-fracturing techniques revealed protein movement within a membrane, while cell fusion experiments showed how proteins were embedded in the lipid bilayer.
• B) The claim is accurate because freeze-fracturing techniques showed how proteins were embedded in the lipid bilayer, while cell fusion experiments revealed protein movement within a membrane.
• C) The claim is inaccurate because freeze-fracturing techniques did not show how proteins or lipids could move about within a membrane as cell fusion experiments did.
• D) The claim is inaccurate because cell fusion experiments did not reveal the distribution of proteins within the lipid bilayer as freeze-fracturing techniques did.
• E) The claim is inaccurate because the fluid mosaic model is supported by evidence obtained from experiments other than those using freeze-fracturing or cell fusion techniques.
