Multiple Choice
What is the general function of enzymes within a cell?
A
They permanently increase the free energy change () of reactions to make them proceed faster.
B
They form the lipid bilayer that separates the cell from its environment.
C
They act as catalysts that speed up biochemical reactions by lowering activation energy without being consumed.
D
They provide long-term storage of genetic information used to make proteins.
Verified step by step guidance1
Understand that enzymes are biological molecules, typically proteins, that facilitate chemical reactions within cells.
Recognize that enzymes do not change the overall free energy change (\$\(\Delta\) G\$) of a reaction; instead, they lower the activation energy required to start the reaction.
Recall that by lowering activation energy, enzymes increase the rate at which reactions reach equilibrium, effectively speeding up biochemical processes.
Note that enzymes are not consumed or permanently altered during the reaction, allowing them to be reused multiple times.
Distinguish enzyme function from other cellular components: enzymes are catalysts, not structural elements like lipid bilayers or storage molecules like DNA.
