The correct answer is proteins.
Proteins have four structures; (1) primary, (2) secondary, (3) tertiary, and (4) quaternary. Primary structures of proteins are formation of peptides and the peptide bonds between amino acids. Secondary structures of proteins involves the amino acid composition leading to hydrophobic interactions forming either alpha helices or beta sheets. Interactions between secondary structures of proteins will make the tertiary structure which is either soluble (globular) or insoluble (fibrous) proteins. Quaternary structures are the combination of two or more tertiary structures and these are called subunits.
In autotrophic bacteria, chlorophyll is located in the infolded regions of the plasma membrane.
Autotrophic bacteria are those that can synthesize their own food. The energy can be derived either from sunlight or from chemical reactions. Only a few amount of bacteria are autotrophic. The examples of such bacteria are: green sulfur bacteria, purple sulfur bacteria, heliobacteria, etc.
Chlorophyll is the green colored pigment involved in the process of photosynthesis. The chlorophyll acts as a reaction center that absorbs the energy from sunlight to initiate the process of photosynthesis. The energy absorbed by other pigments is also transferred to the reaction center.
