Types of Proteins

4. the protein from which silk scarves are made from harvesting silk worms.
5. the protein that makes up 25% of our protein mass; also used to make gelatin when sourced from animals
7. a structural protein that makes the framework inside all of our cells
8. a protein in pineapple that can break down collagen (the most common protein in animals)
10. a protein common to many grains that stores materials in a seed for growing a plant
11. a protein common to animal milk that stores materials for building new proteins
14. proteins that can both carry and walk materials through a cell; the walk on microtubules
15. the proteins in the cells of the eye that can detect light
16. a sticky protein that clogs blood vessels after a cut of scrape
19. the protein that triggers changes in biological females; similar to androgen for males

1. proteins that give some animals an ability to follow magnetic field lines around the Earth
2. a carrier protein responsible for transporting oxygen from the lungs to the body
3. proteins that stick to proteins on cells, marking them for destruction by other parts of an animals immune system
6. a signaling protein that helps regulate sugar
9. the enzyme that helps mammal babies digest lactose sugar in milk
12. found in cell membranes, they allow the fast movement of ions, creating nerve impulses and electromagnetic fields
13. build and break down molecules
17. the most common protein used to create movement in animal tissues
18. proteins that regulate gene expression leading to one type of organ over another
