How many polypeptide chains are shown in the tertiary protein structure in Model 3?

Here, we are required to determine how many polypeptide chains are shown in the tertiary protein structure in Model 3 as shown in the picture attached.

The tertiary protein structure in Model 3 has 1 polypeptide chain/backbone.

Protein tertiary structure is simply defined the three dimensional shape of a protein. By convention, the tertiary structure (TS) of a protein will have a single polypeptide chain otherwise known as the polypeptide backbone with one or more protein secondary structures as the case may be. However, amino acid side chains may interact and bond in a variety of ways as evident in the diagram given.

Explanation:

i dont know this but ask your teacher for !

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
