EOC Review #1: Organic Molecules

Front

What happens to enzyme activity when the temperature exceeds its optimal range?

Back

Enzyme activity decreases and can become zero because the enzyme may be denatured.

Front

What is the primary function of glycogen in animals?

Back

Glycogen serves as a carbohydrate storage molecule in animals.

Front

How does the shape of an enzyme influence its function?

Back

The shape of an enzyme determines the specific reaction it will catalyze.

Front

What distinguishes monosaccharides from polysaccharides?

Back

Monosaccharides are single sugar units, while polysaccharides are made up of two or more monosaccharides bonded together.

Front

What is the optimal temperature for enzyme activity in catalase?

Back

The optimal temperature for catalase activity is 25 °C.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where an enzyme loses its functional shape due to factors like high temperature or pH changes.

Front

What role do enzymes play in biochemical reactions?

Back

Enzymes act as catalysts that speed up biochemical reactions without being consumed in the process.

Front

What is the difference between starch and glycogen?

Back

Starch is the carbohydrate storage in plants, while glycogen is the carbohydrate storage in animals.

Front

Explain the term 'active site' in enzymes.

Back

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

Front

What are the building blocks of carbohydrates?

Back

The building blocks of carbohydrates are monosaccharides.
