Review Questions
How does biochemistry serve as a bridge between biology and chemistry in understanding life processes?
Biochemistry integrates concepts from both biology and chemistry to explain how molecules interact and contribute to life processes. It examines the chemical reactions that occur within cells and how these reactions are regulated. By studying biomolecules like proteins and nucleic acids, biochemistry reveals the molecular foundations of biological functions such as metabolism, signaling, and genetic information transfer.
Discuss the role of enzymes in biochemical reactions and their significance in metabolic pathways.
Enzymes are crucial for facilitating biochemical reactions by acting as catalysts that lower the activation energy needed for reactions to occur. They are specific to particular substrates and play a pivotal role in metabolic pathways by regulating reaction rates. This regulation is vital because it ensures that metabolic processes occur efficiently and respond appropriately to the needs of the cell, influencing overall homeostasis.
