Which of the following descriptors is false regarding enzymes:
a) they affect only the rate of a chemical reaction
b) they lower the activation energy required for a reaction
c) they are proteins
d) they are consumed during the reaction
e) they function as biological catalysts

(d)they are consumed during the reaction

d) they are consumed during the reaction

Explanation:

Enzymes are the biocatalysts that serve to accelerate the rate of the chemical reactions by lowering down the required activation energy.

Enzymes are not used during the reactions. There are no physical or chemical changes in the enzymes during the chemical reactions. After completion of one chemical reaction, enzymes release the products and become available to catalyze the next round of the reaction.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.
