Front

What is the monomer of a carbohydrate?

Back

Monosaccharide

Front

What is a characteristic of saturated fatty acids?

Back

They have a higher ratio of hydrogen to carbon than do unsaturated fatty acids.

Front

Why do enzymes not function well at low temperatures?

Back

Enzymes lack kinetic energy to move quickly.

Front

What is the optimum pH of the enzyme if its activity is greatest around pH 6.6?

Back

6.6

Front

What is cellulose?

Back

A carbohydrate that is a polymer of glucose, used for structural support in plants.

Front

What is starch?

Back

A carbohydrate that is a polymer of glucose, used for energy storage in plants.

Front

What distinguishes saturated fatty acids from unsaturated fatty acids?

Back

Saturated fatty acids have no double bonds between carbon atoms.

Front

What is the role of enzymes in biochemical reactions?

Back

Enzymes act as catalysts to speed up chemical reactions.

Front

What happens to enzymes at high temperatures?

Back

Enzymes can denature, losing their functional shape.

Front

What is the difference between a monosaccharide and a polysaccharide?

Back

A monosaccharide is a single sugar unit, while a polysaccharide is a chain of multiple sugar units.
