What is a dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment, which changes in response to the independent variable.

What role do enzymes play in chemical reactions?

Back

Enzymes are proteins that speed up chemical reactions in the body by lowering the activation energy required.

Front

What is the active site of an enzyme?

Back

The active site is the specific region of an enzyme where substrate molecules bind and undergo a chemical reaction.

Front

What is the primary purpose of monosaccharides in the body?

Back

The primary purpose of monosaccharides is to provide immediate energy for cellular functions.

Front

What is an independent variable in an experiment?

Back

The independent variable is the factor that is manipulated or changed in an experiment to observe its effect on the dependent variable.

Front

Define biochemistry.

Back

Biochemistry is the branch of science that explores the chemical processes within and related to living organisms.

Front

What are substrates in the context of enzymes?

Back

Substrates are the reactants that bind to the active site of an enzyme and are transformed into products.

Front

What is the function of proteins in the body?

Back

Proteins serve various functions including building and repairing tissues, acting as enzymes, and supporting immune function.

Front

What is the difference between a hypothesis and a theory?

Back

A hypothesis is a testable prediction, while a theory is a well-substantiated explanation of an aspect of the natural world.

Front

What is the significance of pH in enzyme activity?

Back

The pH level can affect enzyme shape and function; each enzyme has an optimal pH range for activity.
