How do different enzymes differ?

Enzymes differ from most other catalysts by being much more specific. Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.

How do enzymes work on a molecular level?

Enzymes work by binding to reactant molecules and holding them in such a way that the chemical bond-breaking and bond-forming processes take place more readily. Reaction coordinate diagram showing the course of a reaction with and without a catalyst.

What is the molecular structure of enzymes?

Enzymes are made up of amino acids which are linked together via amide (peptide) bonds in a linear chain. This is the primary structure. The resulting amino acid chain is called a polypeptide or protein. The specific order of amino acid in the protein is encoded by the DNA sequence of the corresponding gene.

What are the two main things enzymes do to other molecules?

Enzymes are the catalysts involved in biological chemical reactions. They are the “gnomes” inside each one of us that take molecules like nucleotides and align them together to create DNA, or amino acids to make proteins, to name two of thousands of such functions.

What is enzymes and its characteristics?

Characteristics of Enzymes: Enzymes are proteins and the properties and characteristics they exhibit reflect properties of protein. They are organic catalysts that speed up biological reactions especially in digestion and metabolism of food substances.

What characteristic features define enzymes?

Characteristics of an Enzyme :

• Speed up chemical reactions.
• They are required in minute amounts.
• They are highly specific in their action.
• They are affected by temperature.
• They are affected by pH.
• Some catalyze reversible reactions.
• Some require coenzymes.
• They are inhibited by inhibitors.

What are the characteristics of enzymes?

What are the two parts of an enzyme?

Enzymes contain a globular protein part called apoenzyme and a non-protein part named cofactor or prosthetic group or metal-ion-activator.

How do enzymes lower activation energy A level biology?

Enzymes generally lower activation energy by reducing the energy needed for reactants to come together and react. For example: Enzymes bring reactants together so they don’t have to expend energy moving about until they collide at random.
