Biology Keystone Review-Part 1

Front

What is denaturation in enzymes?

Back

Denaturation is the process where an enzyme loses its functional shape due to high temperatures or extreme pH levels, leading to a decline in enzyme activity.

Front

What is the monomer of carbohydrates?

Back

The monomer of carbohydrates is a monosaccharide, which is a simple sugar like glucose or fructose.

Front

What do both prokaryotes and eukaryotes have in common?

Back

Both prokaryotes and eukaryotes contain genetic material (DNA).

Front

What biomolecule includes sugars and starches?

Back

Carbohydrates include sugars and starches.

Front

What must occur for an enzyme to catalyze a chemical reaction?

Back

A substrate must bind to the active site of the enzyme.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts that speed up chemical reactions by lowering the activation energy required.

Front

What are the two main types of cells?

Back

The two main types of cells are prokaryotic cells (without a nucleus) and eukaryotic cells (with a nucleus).

Front

What is a substrate in the context of enzyme activity?

Back

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

Front

What is the function of carbohydrates in living organisms?

Back

Carbohydrates provide energy, serve as structural components, and are involved in cell recognition.

Front

What is the difference between simple and complex carbohydrates?

Back

Simple carbohydrates consist of one or two sugar units (monosaccharides and disaccharides), while complex carbohydrates consist of long chains of sugar units (polysaccharides).
