Enzymes Flashcards
What do enzymes control?
Enzymes control the rate of chemical reactions.
What is activation energy?
Activation energy is the energy needed to break or form bonds.
What is the optimum pH range for enzymes?
The optimum pH range for enzymes is 1.5 to 8.5.
What is the active site of an enzyme?
The active site is the region where substrate molecules bind.
What is the enzyme-substrate complex?
The enzyme-substrate complex is formed when an enzyme binds to its substrate.
What is the turnover number?
The turnover number is the number of substrate molecules converted to product per enzyme molecule per second.
What happens during exocytosis?
During exocytosis, enzymes are secreted out of the cell.
What does catalase do?
Catalase breaks down hydrogen peroxide into oxygen and water.
What is the optimum pH for catalase?
The optimum pH for catalase is 7.
What is the role of enzymes in metabolic reactions?
Enzymes facilitate metabolic reactions by lowering the activation energy.
What is the significance of the enzyme’s structure?
The enzyme’s structure is crucial for its function and substrate specificity.
What happens to enzymes as temperature increases?
Enzymes may denature, affecting their active site and substrate binding.
What is the effect of substrate concentration on enzyme activity?
As substrate concentration increases, the rate of reaction increases until it reaches a maximum.
What role do cofactors play in enzyme activity?
Cofactors are non-protein groups that bind to enzymes and are necessary for their activity.
What is the significance of the active site in an enzyme?
The active site is specific for the substrate and facilitates the reaction.
