Question

question 28
enzymes are able to do the following
a. work as biological catalysts
b. absorb excess heat so reactions occur at low temperatures
c. heat up molecules so they can react
d. provide co₂ for chemical reactions
e. become part of the product

Explanation:

Enzymes are proteins that function as biological catalysts. They speed up chemical reactions in living organisms by lowering the activation energy required for the reaction to occur. Option b is incorrect because enzymes do not absorb excess heat; they work best within a specific temperature range. Option c is wrong as enzymes do not heat up molecules; they facilitate reactions through their active - site binding. Option d is incorrect since enzymes do not provide \(CO_2\) for reactions. Option e is wrong because enzymes are not consumed or become part of the product in the reaction (they are regenerated).

Answer:

A. work as biological catalysts
