Primary function of enzymes

Back

Catalysts that lower activation energy

Front

Factors affecting enzyme activity

Back

pH and temperature of the environment

Front

Optimal temperature for amylase

Back

37°C

Front

Amylase denaturation effect

Back

Loses specific shape; cannot catalyze effectively

Front

Enzyme part for substrate binding

Back

Active site

Front

Catalase - Highest reaction rate

Back

Highly efficient in breaking down hydrogen peroxide

Front

Optimal pH and temperature for enzymes

Back

Maintain 3D shape, maximize catalytic activity

Front

Effect of pH on Amylase reaction rate

Back

Decreases away from optimal pH of 7; potential denaturation.

Front

Atoms in carbohydrates

Back

Carbon, Oxygen, Hydrogen

Answer explanation

All carbohydrates are composed of carbon, hydrogen, and oxygen atoms. The correct answer is 'Carbon, Oxygen, Hydrogen' as these elements are essential for forming the structure of carbohydrates like sugars and starches.

Front

Sugar units in monosaccharides

Back

One

Answer explanation

Monosaccharides are the simplest form of carbohydrates, consisting of a single sugar unit. Therefore, the correct answer is one.
