- Protein folding and function.
- Lipid bilayer formation.
- The active site, but irreversibly.
- A site distinct from the active site, causing a conformational change that reduces catalytic efficiency.
- The substrate before it binds to the enzyme.
- Both the active site and the allosteric site simultaneously.
- Binds to a site other than the active site, changing the enzyme's shape.
- Binds reversibly to the active site, competing with the substrate.
- Forms a permanent covalent bond with the active site.
- Increases the enzyme's affinity for its substrate.
- Can catalyze a wide variety of reactions.
- Have active sites that bind to a very limited range of substrates.
- Are unaffected by changes in pH.
- Are equally active at all temperatures.
- It causes the enzyme to denature.
- It increases the chances of enzyme-substrate collisions until all active sites are saturated.
- It directly increases the enzyme's optimal temperature.
- It decreases the activation energy of the reaction.
- High temperatures always denature the active site.
- Low temperatures always activate the enzyme.
- Temperature affects the kinetic energy of molecules, influencing the rate of enzyme-substrate collisions and, at high temperatures, the protein's tertiary structure.
- Enzymes are only active at extreme temperatures.
- Increased enzyme activity.
- Denaturation of the enzyme due to changes in ionization of amino acid side chains.
- Formation of stronger peptide bonds.
- Increased substrate specificity.
- The enzyme's active site is rigid and unchanging.
- The enzyme's active site undergoes a conformational change upon substrate binding, optimizing the fit.
- The substrate changes its shape to fit the active site.
- Enzymes are not specific to their substrates.
- The enzyme's active site is highly flexible and changes shape to fit the substrate.
- The enzyme's active site has a rigid, pre-formed shape that perfectly matches a specific substrate.
- Substrates can bind to any part of the enzyme.
- Enzymes can catalyze a wide range of reactions.
- Are consumed during the reactions they catalyze.
- Increase the activation energy of a reaction.
- Speed up the rate of biochemical reactions without being used up.
- Shift the equilibrium of a reaction.
- Excessive water intake.
- Impaired synthesis of plasma proteins (e.g., albumin) leading to decreased osmotic pressure in blood.
- Increased reabsorption of water by kidneys.
- Damage to muscle tissue causing fluid accumulation.
