homeostasis unit 2 test

Front

What is homeostasis?

Back

Homeostasis is the maintenance of a relatively stable internal environment and often incorporates a form of feedback regulation.

Front

What are enzymes an example of?

Back

Enzymes are an example of proteins.

Front

What is the role of a substrate in enzyme activity?

Back

The substrate is the substance on which an enzyme acts.

Front

What is an active site?

Back

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

Front

What are products in the context of enzyme reactions?

Back

Products are the substances that are produced as a result of an enzyme-catalyzed reaction.

Front

What class of macromolecules do enzymes belong to?

Back

Enzymes belong to the class of macromolecules known as proteins.

Front

What is feedback regulation in homeostasis?

Back

Feedback regulation is a process in which the output of a system regulates its own production, helping to maintain stability.

Front

Why is homeostasis important for living organisms?

Back

Homeostasis is important because it allows organisms to maintain optimal conditions for cellular processes despite external changes.

Front

What factors can disrupt homeostasis?

Back

Factors such as temperature changes, pH levels, and concentration of ions can disrupt homeostasis.

Front

How do enzymes speed up chemical reactions?

Back

Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to occur.
