Which of the following are survival needs of the body?

A. Secondary structure: The secondary structure of a protein involves local folding patterns of the polypeptide backbone, including alpha helices and beta sheets, stabilized by hydrogen bonds between backbone atoms. The coiling into an alpha helix is a classic example of this level.

B. Primary structure: The primary structure is the linear sequence of amino acids in the polypeptide chain, without any folding or coiling.

C. Tertiary structure: Tertiary structure refers to the overall three-dimensional folding of a single polypeptide chain due to interactions between side chains, not the coiling of the backbone.

D. Quaternary structure: Quaternary structure arises when multiple polypeptide chains or subunits come together to form a functional protein complex, beyond the level of alpha helix formation.

A. Kinetic: Kinetic energy is the energy of motion, such as moving muscles or flowing blood, and is not stored energy.

B. Effective: “Effective energy” is not a standard classification in physics or biology; it does not specifically describe stored energy.

C. Energy: Energy is a general term and does not differentiate between stored and active forms.

D. Potential: Potential energy is stored energy that has the capacity to do work in the future, such as chemical energy in bonds, a stretched spring, or gravitational energy in elevated objects.
