Enzymes are important because they?

A. contain water***
B. speed up chemical reactions
C.contain genetic material
D.help the cell maintain it shape

it is B, it is not A because

Enzymes are proteins that control the speed of chemical reactions in your body. Without enzymes, these reactions would take place too slowly to keep you alive. Enzymes also help cells to communicate with each other, keeping cell growth, life and death under control.

It is B. They speed up chemical reactions.

The unit test review on the message board says "Enzymes are proteins that speed up chemical reactions in the body. Enzymes can also help some materials cross the cell membrane."

I thought it was a . contain water but I don't really know ....

The correct answer is B. Enzymes speed up chemical reactions.

Enzymes are proteins that act as catalysts in biological reactions. They function by lowering the activation energy required for a reaction to occur, thus increasing the rate of the reaction. This means that enzymes speed up chemical reactions that would typically occur too slowly or require too much energy to proceed.

To determine the correct answer, you can use your knowledge about enzymes or do some research. Enzymes are well-known for their role in speeding up chemical reactions in living organisms. You can learn about this concept by referring to biology textbooks, online resources, or scientific articles. Understanding the function of enzymes in biological systems will help you recognize that they increase the rate of chemical reactions.
