A peplomer is a glycoprotein spike on a viral capsid or viral envelope. These protrusions will only bind to certain receptors on the host cell; they are essential for both host specificity and viral infectivity.
Answer:
e. regenerates a three-carbon molecule and alcoholic fermentation does not.
Explanation:
Lactic acid fermentation includes the reduction of pyruvate into lactate. Lactate is a three-carbon molecule. Reduction of pyruvate into lactate also regenerate NAD+ required to continue the process of glycolysis.
Alcoholic fermentation includes decarboxylation of pyruvate into acetaldehyde followed by its reduction of alcohol. The alcohol formed as end product is a two-carbon molecule (ethanol). Here, NADH serves as electron donor and is oxidized into NAD+. Therefore, both the process regenerate NAD+ but ethanol fermentation does not regenerate the three-carbon molecule since one carbon is lost as CO2.
I wouldnt say a vaccine destroys a virus. it is supposed to give a small dosage of the virus so the immnune system fights it off and recongnises it in the future
