What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions in the body without being consumed in the process.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, producing glucose and oxygen as byproducts.

Front

What are macromolecules?

Back

Macromolecules are large, complex molecules that are essential for life, including carbohydrates, proteins, lipids, and nucleic acids.

Front

What is the main function of carbohydrates in living organisms?

Back

Carbohydrates serve as the primary source of energy for living organisms.

Front

What is a substrate in the context of enzyme activity?

Back

A substrate is the specific reactant that an enzyme acts upon during a chemical reaction.

Front

What does it mean for an enzyme to be specific?

Back

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

Front

What are the products of photosynthesis?

Back

The products of photosynthesis are glucose and oxygen.

Front

What type of macromolecule are enzymes classified as?

Back

Enzymes are classified as proteins.

Front

What is the lock and key model in enzyme activity?

Back

The lock and key model describes how a specific substrate (the key) fits into the active site of an enzyme (the lock) to form a product.

Front

What is the difference between a catalyst and an enzyme?

Back

A catalyst is a substance that increases the rate of a chemical reaction, while an enzyme is a specific type of catalyst that is biological in nature.
