Which of the following would occur if cells did not have enzymes? a. Reactions in cells would occur too slowly to sustain life. **** b. Reactions in cells would occur too quickly to sustain life. c. Reactants would not be able to combine cells. d. Reactants would combine with products in cells.
the right answer is A. reactions in cells would occur too slowly to sustain life
The correct answer is: a. Reactions in cells would occur too slowly to sustain life.
Enzymes are proteins that act as catalysts in biological reactions. They increase the rate of chemical reactions by lowering the activation energy required for the reaction to occur. Without enzymes, the reactions in cells would proceed at extremely slow rates, making it difficult for essential processes to take place in a timely manner, ultimately hindering the ability of cells to sustain life.
To find the answer to this question, we can break down the options provided and analyze each one.
a. Reactions in cells would occur too slowly to sustain life.
b. Reactions in cells would occur too quickly to sustain life.
c. Reactants would not be able to combine cells.
d. Reactants would combine with products in cells.
Enzymes are biological catalysts, meaning they increase the rate of chemical reactions in cells without being consumed. They play a crucial role in speeding up various cellular processes, such as metabolism and DNA replication.
Option a states that if cells did not have enzymes, reactions would occur too slowly to sustain life. This is the correct answer because without enzymes, the rate of chemical reactions in cells would significantly decrease. Many vital cellular processes rely on enzymes to proceed at a suitable rate for life to be sustained. Consequently, without enzymes, these necessary processes would be too slow, leading to an inability to sustain life.
To summarize, if cells did not have enzymes, the correct answer is option a - Reactions in cells would occur too slowly to sustain life.
