Function of Protein

Genes Code for Proteins

What are 5 functions of proteins in the body?

Open Ended

A)      ____ A microtubule is a protein structure that provides a track for a motor protein which moves a vesicle.

B)      ____ A motor protein, kinesin, walks along a microtubule carrying a vesicle with its contents.

C)      ____ A porin protein provides a channel for a small molecule to diffuse across a cell membrane.

D)      ____ Collagen is a long protein with several polypeptides twisted together like a rope or cable. Collagen gives strength to the tendons and ligaments which connect bones and muscles.

Which description goes with each picture?

​

​Most protein enzymes have a similar overall globular shape, but each enzyme has an active site with a unique structure that matches the enzyme’s function. The enzyme in this figure breaks down a maltose molecule to two glucose molecules.

Open Ended

The diagram shows how the shape of the active site of the enzyme matches the shape of the molecule it interacts with, maltose. Explain why this enzyme would break down maltose, but would not break down collagen into its component amino acids

Explain what a gene is. (If needed, review the video “What are DNA and genes?”)

​ 

Different people may have different versions of a gene, and these different versions of a gene give the instructions to make different versions of a protein. Different versions of a protein can result in different characteristics. This table shows an example.

Complete this diagram to show how a gene gives the instructions to make a protein. Include in your diagram:

DNA, gene, RNA, ribosome, protein, and amino acids

 Explain how the different versions of a gene determine whether a person exhibits albinism or not.
