Answer the following statements true (T) or false (F)

Question

1. Of the 20 amino acids in all organisms, essential amino acids are obtained by food consumption.

2. If a protein is denatured, its structure has been changed enough to make the protein nonfunctional.

3. Proteins store the genetic information of the cell and transmit it to the next generation.

4. When Herceptin medication is used to stop the excessive action of receptor proteins in breast cancer cells, slowing their division, the receptor proteins are within the cell nucleus where the cell is regulated.

5. Endosymbiosis theory is proposed in large part because of the resemblance of mitochondria and chloroplast structures to prokaryotes.

Answer 1

1. TRUE
There are eight amino acids that humans gain from protein-rich foods.

2. TRUE
Normal functions of proteins cease if the three-dimensional structure is changed by various conditions.

3. FALSE
Although proteins have many functions, and have structures determined by the DNA genetic code, protein functions do not include storage and inheritance of genetics.

4 .FALSE
Receptor proteins partially describe their role in "receiving" something for the cell, which would not happen in the nucleus in the center of the cell.

5.TRUE
Shared structure and function between chloroplasts, mitochondria, and prokaryotes include membranes, DNA, and ribosomes.
