Cellular organelles generally have different structures because these structures govern the specific functions of each organelle within the cell and stimulate its survivability.
What do you mean by Cell organelles?
Cell organelles may be defined as the types of subcellular structure that significantly has to perform one or more specific functions in the cell. For example, the nucleus stores genetic material, mitochondria produce chemical energy, etc.
The structure of each and every cellular organelle is based on its function. For example, the nucleus is enclosed by a double membraneous layer that stores the genetic material of an organism. It also has pores (nuclear pores) that allow the passage of substances in and out.
Golgi apparatus has numerous projections that allow them to transport functional proteins to their targeted site from the nucleus or ER. Mitochondria has cristae, matrix, ribosomes, etc. that facilitate the production of chemical energy and hence it is known as the powerhouse of the cell.
Therefore, cellular organelles generally have different structures because these structures govern the specific functions of each organelle within the cell and stimulate its survivability.

Answer:
In the α helix structure, there is a hydrogen bonding between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain
Explanation:
The common secondary structure of protein are: α helix and β pleated sheet
α helix is a rod like structure.It is a right handed coil of amino acid residue on a polypeptide chain, which may be 4 units or 40 units long. The coil is held together by hydrogen bond between oxygen atom in a carbonyl of one amino acid and the hydrogen atom of the amino group that is situated four residues farther along the polypeptide chain. This means that every complete turn of the helix is only 3.6 residues.
Final answer:
In an alpha helix, hydrogen bonds are formed between the carbonyl oxygen of one amino acid and the hydrogen attached to the nitrogen atom of another amino acid that is four residues away in the same polypeptide chain. This results in the characteristic spiral structure of an alpha helix.
Explanation:
In an alpha helix, a type of secondary structure in proteins, there is a specific pattern of hydrogen bonding that helps maintain its spiral shape. The hydrogen bond is formed between the carbonyl oxygen (C=O) of one amino acid and the hydrogen (H) attached to the nitrogen atom (N-H) of another amino acid that is four residues away in the same polypeptide chain. This repeated pattern of hydrogen bonding results in the characteristic spiral structure of the alpha helix. In terms of polypeptide numbering, if the amino acid at position n in the chain forms a hydrogen bond, then it does so with the amino acid at position n+4. This bonding pattern, along with the characteristics of the specific amino acids involved, contributes to the overall stability and function of the protein.
