what are 2 essential roles that enzymes play in cells?

Two essential roles that enzymes play in cells are:
1. Catalysts of biochemical reactions: Enzymes act as catalysts, accelerating the rate of biochemical reactions that occur within cells. They lower the activation energy required for a reaction to proceed, enabling cellular processes to occur at a much faster rate than without enzymes. This helps to maintain the overall efficiency of cellular metabolism.
2. Regulation of metabolic pathways: Enzymes also play a crucial role in regulating metabolic pathways within cells. They control the flow of biochemical reactions by activating or inhibiting specific steps in a pathway. This regulation allows cells to respond to changes in environmental conditions and metabolic demands, ensuring the proper balance of metabolic reactions.
To find this information, you can refer to biology textbooks, scientific articles, or reputable online sources that cover the topic of enzymes and their roles in cellular processes. Some recommended sources include molecular biology textbooks, biology websites, and academic journal articles related to enzymology and cellular metabolism.
