Study Notes
Biomimicry in Design
- Biomimicry draws inspiration from natural forms and principles in fields such as architecture, engineering, and material science.
- Combining aesthetics with functionality leads to innovative designs that enhance performance.
Nature as a Problem Solver
- Nature's solutions to challenges provide insights for technological and engineering endeavors.
- By imitating biological strategies, new approaches to complex problems can emerge.
Promoting Sustainable Development
- Utilizing biomimicry fosters sustainable practices across various industries.
- Encourages eco-friendly innovations that minimize impact on the environment.
Innovations from Biological Systems
- Biological systems offer diverse structures, functions, and processes that inspire technology advancement.
- Exploration of these biological concepts can lead to the creation of novel products and technologies.
Interdependence of Biology and Technology
- Biological research often informs technological innovation, creating a reciprocal relationship.
- Advancements in technology also aid in understanding and studying biological phenomena.
Enzyme Regulation and Activity
- Enzyme regulation controls enzymatic activity, activating or deactivating enzymes based on the organism's needs.
- Regulatory enzymes are classified into two groups: allosteric enzymes and covalently modulated enzymes.
- Enzyme inhibitors decrease enzyme activity and are divided into two types: reversible and irreversible inhibitors.
Enzyme Kinetics
- Enzyme kinetics studies the rates of reactions catalyzed by enzymes and the binding affinities of substrates and inhibitors.
- Enzymes accelerate reactions by lowering the activation energy required for reactants to form products.
- The Michaelis-Menten formula describes the relationship between reaction rate and substrate concentration, highlighting the maximal catalytic rates.
Applications of Enzymes
- Enzymes are utilized in various industries, including food, feed, textiles, papermaking, leather, detergents, and pharmaceuticals.
- Malting converts grain into malt through three steps: steeping, germinating, and kilning.
Traditional vs. Modern Malting
- Traditional malting involves sprouting barley grains to produce enzymes like α-amylase and β-amylase for fermentation drinks such as Tella.
Common Misconceptions about Enzymes
- The lock-and-key model suggests rigidity; enzymes are actually flexible and can change shape to fit substrates.
- Enzymes can interact with multiple substrates, contrary to the idea of being specific to one.
- The induced fit model implies static binding; enzymes and substrates undergo conformational changes during binding to optimize interaction.
- Optimal enzyme activity is associated with 37°C, but enzymes can function effectively at various temperatures, including extremes.
- Enzymes are not always active at maximum capacity; their activity is regulated according to cellular conditions.
- Enzymes influence the reaction kinetics rather than altering the thermodynamics or equilibrium of reactions.
- The Michaelis-Menten model accounts for reversible binding, contrary to the assumption of irreversible binding.
