Answer:
The E zone portion of the protein
Explanation:
The glucagon hormone which is a signal molecules that triggers a reaction in the liver cells is most likely to bind to the E zone extracellular portion of the G-protein-coupled receptor. This then changes the conformation of the receptor activating the heteromeric G proteins.
Answer:
2
Explanation:
Humans need proteins, fatty acids, vitamins, and minerals
Solution:
Phospholipid lipids is that contribute to the structure and function of the cell membrane.
Lipids all have one thing in common - they do not mix well with water. You can see this quite well if you try to combine oil and water. No matter how much or how hard you shake them together, they remain separated. This can be useful for organisms. For example, ducks produce lipids in their feathers, allowing the water to roll right off their backs and helping the ducks stay afloat.
Phospholipids are made up of two fatty acids (long chains of hydrogen and carbon molecules), which are attached to a glycerol 'head.' The glycerol molecule is also attached to a phosphate group, and this is the hydrophilic part of the molecule. The 'tail' ends of the fatty acid chains opposite the glycerol is the hydrophobic part of the molecule
The most important function for a phospholipid is to form the phospholipid bilayer. In this bilayer, the phospholipids are arranged so that all the hydrophillic heads are pointing outward and the hydrophobic tails are pointing inward. This arrangement comes about because the areas both outside and inside your cell are mostly water, so the hydrophobic tails are forced in.
THis is the required answer.
