Question

1. the sodium - potassium ion pump found in some cell membranes is made of which of the following basic structural components? a amino acids b fatty acids c monosaccharides d nucleotides 7. what is a primary function of the cell membrane? a determining genetic traits b defending against foreign particles c breaking down proteins for energy d generating energy from mineral nutrients 8. why does the study of cell membranes lead to a better understanding of cell function? a all cell functions occur in the cell membrane. b all energy transfers occur at the cell membrane. c all cell membranes contain the information for making proteins. d all materials needed for cell functions must pass through the cell membrane.

Explanation:

Question 6:

The sodium - potassium ion pump is a protein. Proteins are composed of amino acids. Fatty acids are components of lipids, monosaccharides are building blocks of carbohydrates, and nucleotides are building blocks of nucleic acids.

Question 7:

One of the primary functions of the cell membrane is to act as a barrier and defend against foreign particles. Determining genetic traits is related to DNA, breaking down proteins for energy occurs in cellular respiration processes not mainly at the cell - membrane, and generating energy from mineral nutrients is not a primary function of the cell membrane.

Question 8:

All materials needed for cell functions must pass through the cell membrane. Not all cell functions occur in the cell membrane (many occur in the cytoplasm and organelles), not all energy transfers occur at the cell membrane (e.g., some occur in mitochondria), and the information for making proteins is in DNA, not in all cell membranes.

Answer:

Question 6: A. amino acids

Question 7: B. defending against foreign particles

Question 8: D. All materials needed for cell functions must pass through the cell membrane.
