Biomolecules, Enzymes, Cell Basics Flashcard

Front

What is a ribosome?

Back

A small structure involved in protein synthesis.

Front

What can cause an enzyme to become denatured?

Back

High temperature or extreme pH.

Front

What is the role of an enzyme in a chemical reaction?

Back

The enzyme is necessary to lower activation energy.

Front

Which cell structure controls what enters and leaves the cell?

Back

Cell membrane.

Front

What happens to an enzyme when the temperature increases significantly?

Back

The enzyme may denature and lose its function.

Front

What are biomolecules?

Back

Large molecules essential for life, including proteins, nucleic acids, carbohydrates, and lipids.

Front

What is the function of enzymes?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What is denaturation in the context of enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, such as heat or pH changes.

Front

What is the primary structure of proteins?

Back

The sequence of amino acids in a polypeptide chain.

Front

What is the function of the cell membrane?

Back

To protect the cell and regulate the movement of substances in and out.
