1. What is homeostasis and why is it crucial for cellular function?

 - Homeostasis refers to the ability of an organism to maintain a stable

internal environment despite external changes. It is vital for cellular

function as it ensures optimal conditions for metabolic pathways and

enzyme reactions, allowing cells to carry out their various functions

effectively.

2. Describe the role of metabolic pathways in cellular homeostasis.

 - Metabolic pathways are a series of interconnected chemical reactions

that occur within cells. They play a crucial role in maintaining cellular

homeostasis by allowing for the efficient production of energy and

necessary molecules, as well as the removal of waste products.

3. How do enzymes contribute to maintaining cellular homeostasis?

 - Enzymes are proteins that act as catalysts, speeding up chemical

reactions within cells. They play a vital role in maintaining cellular

homeostasis by facilitating metabolic pathways, ensuring that reactions

occur at an appropriate rate to meet the cell's needs.

4. Explain the concept of feedback regulation in metabolic pathways and

its significance for homeostasis.

 - Feedback regulation refers to the control of metabolic pathways by

products or intermediates within the pathway. It helps maintain cellular

homeostasis by regulating the rate of reactions and preventing the
