Which of the following statements is FALSE? A) Proteins can be structural components of cells. B) Proteins can transmit signals between cells. C) Proteins can transport molecules within cells and between cells. D) Proteins can be both hormones and hormone receptors. E) Proteins are the only biological polymer that can catalyze biochemical reactions. E

The correct answer is: E) Proteins are the only biological polymer that can catalyze biochemical reactions.

Explanation:

Proteins are molecules of great importance to the body as they perform many functions that are key to our survival, from catalyzing reactions to transmitting signals. They can be hormones and receptors, as well as perform structural functions and provide transport to cells and organelles.

The correct option is (E). Proteins are the only biological polymer that can catalyze biochemical reactions.

Explanation:

In analysing the answer contained in option "E," it is correct that protein has the following properties:

Yes, protein is a biological polymer but not the ONLY one in the body. There are other biological polymers such as:

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
