Cellular Processes

What are catalysts?

• Substances that increase the rate of a chemical reaction without being consumed.

• Substances that slow down a chemical reaction.

• Substances that are consumed in a chemical reaction.

• Substances that change the color of a chemical reaction.

What is the significance of enzymes in biological systems?

• They facilitate and regulate biochemical reactions essential for life.

• They are the primary source of energy for cells.
