Enzymes

Front

What is the enzyme-substrate complex?

Back

The enzyme-substrate complex is a temporary molecule formed when an enzyme comes into contact with its substrate. It is crucial for catalyzing biochemical reactions.

Front

What is a substrate in the context of enzymes?

Back

A substrate is any substance that is acted upon by an enzyme during a biochemical reaction.

Front

What factors can change the shape of an enzyme?

Back

Excessive heat and changes in pH can denature enzymes, altering their shape and function.

Front

Why are enzymes necessary for cellular reactions?

Back

Enzymes are necessary because they speed up reactions that would otherwise occur too slowly to meet the needs of the cell.

Front

What are enzymes primarily made of?

Back

Enzymes are primarily made of proteins.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where the substrate binds and the reaction occurs.

Front

How do enzymes lower the activation energy of a reaction?

Back

Enzymes lower the activation energy by stabilizing the transition state and providing an alternative reaction pathway.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to choose exact substrates from a group of similar chemical molecules.

Front

What role do coenzymes play in enzyme activity?

Back

Coenzymes are organic molecules that assist enzymes in catalyzing reactions, often by acting as carriers for chemical groups.

Front

What is denaturation in relation to enzymes?

Back

Denaturation is the process in which an enzyme loses its functional shape due to external stressors like heat or pH changes.
