Chicken egg contains a lot of proteins which supports the growth and development of the chicken embryo. The chicken egg was placed on high heat (100°C) until it forms a solid structure. Which of the following statements is correct about the given scenario? O The increase in temperature may interfere intermolecular forces of attraction that stabilizes the native conformation. O Structural and functional characteristics of proteins remain intact even temperature was increased to boiling O Extreme temperature conditions may result to irreversible denaturation due to destruction of primary. secondary, tertiary, and quaternary structures By decreasing the temperature, the egg embryo can still develop, and grow to become a chicken because renaturation may take place.
Proteins undergo a process, called folding to establish their final, functional configuration. Amino acids them selves are covalently, bound to gather, but for other forces are needed to maintain a functional proteins structure. Briefly describe these forces.
