What Is the Function of Ribosomes (Also Known as Ribosomal

question 14

Multiple Choice

What is the function of ribosomes (also known as ribosomal RNA) in protein synthesis?

• A)Allows interpretation of the two strands of DNA to determine which is the "sense" strand and which is the "antisense" strand
• B)Serves as the coordinator mechanism to allow proper reading of the mRNA and placement of the correct amino acid in the sequence by the tRNAs
• C)Allows further processing of synthesized proteins (post-translational modification in order to ensure that the final product is physiologically active)
• D)Serves as a transport molecule able to move a specific amino acid to the site of protein synthesis (peptide chain elongation)in the correct sequence

Definitions:

Noncyclic Electron Pathway

A part of photosynthesis where electrons travel in a linear path producing NADPH and ATP, unlike in the cyclic pathway where electrons are recycled.

Noncyclic Electron Pathway

A part of photosynthesis that involves the flow of electrons from water to NADP+, producing oxygen, ATP, and NADPH.

Electron Transport Chain

A series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, coupled with the transfer of protons (H+ ions) across a membrane, generating ATP.

Antenna System

In photosynthesis, it refers to a complex of proteins and pigments that captures light energy and channels it to the reaction center.
