question 2
for this figure of membrane proteins match the letters in the figure with the most accurate te

Explanation:

To solve this matching problem, we analyze each term and its corresponding definition:

1. Proteins bound to the surface of the plasma membrane

These are Peripheral membrane proteins (they attach to the membrane surface, not embedded).

2. States that a membrane is a fluid structure with various proteins embedded in it

This is the Fluid Mosaic Model (describes membrane structure as fluid with embedded proteins).

3. Allowing some substances to cross more easily than others

This is Selective Permeability (defines the membrane’s ability to regulate substance passage).

4. Proteins that penetrate the hydrophobic core of the plasma membrane like transmembrane proteins

These are Integral membrane proteins (they span or penetrate the membrane’s hydrophobic region).

5. Containing hydrophobic and hydrophilic regions

These are Amphipathic Molecules (e.g., phospholipids have both hydrophobic tails and hydrophilic heads).

6. Integral membrane proteins that span the membrane

These are Transmembrane proteins (a type of integral protein that crosses the entire membrane).

7. The most abundant lipid in the plasma membrane

This is Phospholipids (they form the basic membrane structure).

Answer:

s (matching each term to definition):

1. Proteins bound to the surface of the plasma membrane: Peripheral membrane proteins
2. States that a membrane is a fluid structure with various proteins embedded in it: Fluid Mosaic Model
3. Allowing some substances to cross more easily than others: Selective Permeability
4. Proteins that penetrate the hydrophobic core of the plasma membrane like transmembrane proteins: Integral membrane proteins
5. Containing hydrophobic and hydrophilic regions: Amphipathic Molecules
6. Integral membrane proteins that span the membrane: Transmembrane proteins
7. The most abundant lipid in the plasma membrane: Phospholipids
