Enzyme Activity and Interactions

A series of vocabulary flashcards covering key terms related to enzyme interactions and mechanisms discussed in the lecture.

Active Site

The region of an enzyme where substrates bind and undergo a chemical reaction.

Lock and Key Model

A model that suggests that the enzyme and substrate fit together perfectly without any changes in shape.

Induced Fit Model

A model that suggests that the enzyme changes shape to better fit the substrate after binding.

Hydrophobic Interaction

A type of non-covalent interaction between non-polar molecules, helping to stabilize the structure.

Salt Bridge

An electrostatic interaction between positively and negatively charged side chains in proteins.

Pyruvate Kinase

An enzyme that catalyzes the transfer of a phosphate from phosphoenol pyruvate to ADP to form ATP.

Phosphate Group

A chemical group consisting of a phosphorus atom bonded to four oxygen atoms; carries negative charges.

Transferase

An enzyme category that transfers a functional group from one molecule to another.

Adenosine Triphosphate (ATP)

A molecule that carries energy within cells; consists of adenosine and three phosphate groups.

Cofactor

Non-protein chemical compounds or metal ions that are required for the biological activity of an enzyme.
